The tokamak-devices will be combined with the toroidal synchrotron,then it will become an ideal ion electric thruster in the spacefighter,in spite of the more higher energy losses than the long-range cylinder-shaped spacetransporter which use a linear accelerator as its thruster when accelerating the ion-flows,but it is best suitable for the middle/short-range saucer-shaped spacecraft.In the first place,the particles of the ionizable substances will be ioned and accelerated preliminarily by a lots of simple hall effect thrusters at the center of the circular ring,and then this ion will be guided by the linear accelerator into the toroidal container of the the toroidal synchrotron combined with the tokamak-devices,inside it,the ion-flows will be cotained,and compressed,and reaccelerated.There is a strong induced-electric-current in the plasma-circumfluence,so it will keep on pinching,and it will be maintained in the toroidal container which is circling round in a high speed for a long time, before it will be guided and spouted out by the magnetic-field of the thrust-vector nozzle.If the plasma-circumfluence maintained in the toroidal container will not be spouted out,it will be decelerate ,and absorbed, and recycled,that to reduce the wastes of the propelling medium an the energy.When this plasma-circumfluence has being accelerated to close to the speed of light,it will provide an ion beam as a kind of directed energy weapon，it is a kind of middle/short-range weapon of defence(It will be optimal if it use all the ion of antimatter as the ion beam weapon.).We will construct a kind of compressing plasma ball which like some ball lightning in the earth's atmosphere,that it will be shotted out to attack the military target and will be automatically explosive as a bomb or shell,because it contains a strong induced-electric-current,it is a kind of long-range weapon(It will be optimal if it use all the ion of antimatter as the ball lightning.).In addition,this plasma-circumfluence will create the X-ray laser coming from the synchrotron radiation or the cyclotron radiation when it is being accelerate.And if we spout the ion of antimatter in it,it will create the more powerful and penetrable γ–ray laser coming from the antimatter/matter reaction,which will be a more stronger long-range weapon.

It is almost a general principle to fit two major engines in the fighter plane.There are plenty of causes which include the equilibrium of torque,the guarantee of security and vulnerability resistant,the request of thrust and andacceleration.Then the saucer-shaped spacecraft will also be fitted two major ion electric thruster which will be positioned horizontally,and seen as a whole,they look like two piece of discs.This two piece of discs(ion electric thruster) will overlap with each other and lay around the rotating shaft in the center.There are air entries both on the top and the bottom of the airframe which will appear as a ring-shape.There are a plenty of the thrust-vector nozzles wounding round the circumferential edge of the ion electric thruster,which will not affect each other.The thrust-axis of the engine will cut through the center of mass in the airframe.The direction of the accelerated plasma circumfluence in the engine will be opposite,then the two reverse torques will also be opposite that will achieve an equilibrium,so the form of fitting between the engine and the airframe is optimal.The three varieties of ion accelerator in the engine have a good regularity and rationality in fitting and structure,the construction members have been completely electrified,so that it has a high reliability and firmness, and easy to overhaul.When the two engines of the saucer-shaped spacecraft are working,it will appear two kinds of wakes,one will like the swallow-tail when it want to achieve a high acceleration after sprouting out the large mass and great speed of ion-flows,and the other will like the rod/band when it want to achieve a constant low speed after sprouting out the small mass and low speed of ion-flows.

The most important thing of the spacefighter flying in the space is the energy source. There will be no doubt that the only selection of the spacefighter will come from the antimatter/matter reaction. In this place,we will idealize the substance of antimatter. Suppose the civilization of human being have entered the space age, the technologies about the nuclear fusion and the robot and the artificial intelligence have been highly matured, the energies of the sunlight and the nuclear fusion will be widely created and used(Even the hydrogen isotope and helium isotope will be exploited.), the robot and the artificial intelligence technology will be used in exploiting the space, then the future productive forces of human being will be as several hundreds million times as that of nowadays, then it will not be an imagine to product a certain amount of the substance of antimatter. If we will make further efforts to turn the anti-hydrogen to metallized superconductor under the low temperature and high pressure conditions(The metallized hydrogen is a superconductor.), then we will have the metallized anti-hydrogen be contained and preserved in a vacuum magnetic trap. When the thrust media of the saucer-shaped spacecraft have been used up, we will achieve the light pressure in a special explosion chamber coming from the γ-rays of the antimatter/matter reaction(This special explosion chamber will resist the penetration of the γ-rays.), and it become a photon propulsion. We might as well mix the γ-rays with the space particles or the space trash to spout out from the great nozzle on the bottom of airframe, and this will achieve a higher thrust and efficiency; If the adsorbed cosmic-dusts or gas-molecule or ion-flows are relatively few, it will sprayed directly the "meson-flow" out of the bottom spout to obtain thrusts that under the constraint of magnetic field. Among them there is a kind of ring-tubular storage-box of superconducting magnetic levitation, which will specially preserve a large mass of superconducting material, and it will sustain a great acceleration in every direction and not to touch the superconducting antimatter with the wall of this storage-box.

The saucer-shaped spacecraft will have to resist the concentrated bursts of all sorts of high power rays/ions when flying in the space,especially resist the attack of the directed energy weapon such as the laser of γ-rays and the ion beam weapon.And it will have to fly in the atmosphere of the sun which always create a plenty of strong solar storms that generally consist of the high temperature plasma-flows and the strong magnetic-fields intertwining each other which will burst finally,so it will need to make a cooling and insulate the heats on the surface of the airframe.In the end of the inference,we present a structure of taking the plasma-circumfluence(a ring of light) containing the strong induced-electric-current out to the surface of the airfame,and this plasma-circumfluence(a ring of light) will be expanded from the center to the periphery which is a multi-ring structure.First of all,we will fit an openable plasma-circumfluence generator in the top and bottom of the saucer-shaped spacecraft,which is same as the tokamak-device, and will creat the same kind of plasma-circumfluence.But this kind of plasma-circumfluence has not too high temperature,and is not required to produce a nuclear fusion reaction,and it will also have a certain speed and a strong induced-electric-current/magnetic ,that will keep pinching it.The most difference between them is that the plasma-circumfluence will be release out of the generator.This openable plasma-circumfluence generator will be close at the beginning,then we will spout a certain speed of plasma-flows in the toroidal container of this generator,the electric-field and the magnetic-field of this generator will pinch the plasma-flows into a compressed plasma-circumfluence(a ring of light),and then the outer margin of the wall of this generator will open which is under a reducing magnetic-field,and be freely released outward the plasma-circumfluence under the actions of the centrifugal force and a reducing magnetic-field one after another.But this plasma-circumfluence(a ring of light) will also be steadily constrained by a symmetrical fixed-magnetic-field of the airframe's surface,till it be broken by self at the outer margin of airframe.

Fig.2.6|
This plasma-circumfluence(a ring of light) will be released and squeezed outward,and will be separated from the skin of the airframe under the constrain of the symmetrical magnetic-field of the airframe's surface.And we will even spout the liquid nitrogen/helium to cool the boundary layer between the plasma-circumfluence and the skin of the airframe.This plasma-circumfluence will have not only a certain flow-speed but also the strongest induced-electric-current/magnitic，so it has a more stronger explosible energy than the ball lightning,then make it become a magnetofluid armor,which will be a new kind of armor.When this plasma-circumfluence(a ring of light) is colliding with the small meteorolite or shrapnel,it will produce an exploding and shearing action.And this action of the plasma-circumfluence(a ring of light) is same as the explosive reactive armor (ERA) of the tank，which is more like a new kind of electromagnetic armor.But it will be used to resist all kinds of the high-speed ion beam and the magnetic blast(the magnetic reconnection) of the solar storm,and it will insulate the airframe from the high heats and strong radiations.This plasma-circumfluence(a ring of light) will also be steadily constrained by a symmetrical fixed-magnetic-field of the airframe's surface,till it be broken by self at the outer margin of airframe.The broken plasma-circumfluence will be constrained more steadily by a symmetrical fixed-magnetic-field of the airframe's surface,and then flows towards the centre of a circle,which will become a planar vortex whose substances will be reused again.In fact,the saucer-shaped spacecraft will have to resist too many kinds of attack which including the meteorolite/space trash, armor piercing shell/high explosive antitank projectile,neutron bomb/space mine,ion beam weapon,particle beam weapon,gamma-ray laser weapon,and the most powerful saucer-shaped antimatter missile/unmanned aerial vehicle.So the saucer-shaped spacecraft will have to fit more kinds of and stronger armors.We will also use the fixed-magnetic rod beams made up of the electrified superconducting-solenoids which are fitted under the surface of the airframe as another kind of batterie and the armor.Beacause the electrified superconducting-wires will produce an exploding and shearing action with the electric heating and the magnetic-field fluctuations when it colliding with the small intruder,so the fixed-magnetic rod beams fitted under the surface of the airframe is also another kind of electromagnetic armor.Of course the saucer-shaped spacecraft also has the usual kind of composite armor,the other kind of armor and active defence technology.

If the spacefighter use the antimatter nuclear energy as the major energy, we will need to convert the nuclear energy into the electricity,and we have to maintain the high-capacity and high-density batteries. In addition,when we are flying and fighting in deep space with nothing(but not in the near of the major planets),the thrust medium of the thruster will be very limited. Althought we will not confirm how many varieties of the batteries will possess the saucer-shaped spacecraft, but one kind of battery will be fitted in it. Namely it is the plenty of the electrified superconducting solenoids fitted in the airframe, which may be acted as a kind of superconducting magnetic energy-storage-system/battery. Such as the fixed-magnetic rod beams fitted under the surface of the airframe is not only a kind of electromagnetic armor, but also a kind of superconducting magnetic energy-storage-system/battery. For the sake of making the fixed-magnetic-field become more symmetrical and the superconducting solenoids become more long, this fixed-magnetic rod beams will be fitted in a form of archimedes spiral, instead of a form of straight line. When the thrust-media's quantities of the saucer-shaped spacecraft are small, this form of archimedes-spiral's electrified superconducting solenoids will be stretched out the airframe which will become a form of funnel. Beacause this solenoids have a stream of strong electric in it, so it become a magnetic funnel. When this magnetic funnel will be twirled with a hign speed, it will adsorb the ion-flows near the sun, or the gas-molecules on the atmosphere's top of the major planets, or the ionized cosmic-dusts in space (that we will use the high energy laser or spout out the high speed's electron beam to get the ionization.), and use them as the thrust medium of the thruster, or as the "positive-matter" side of "positive and antimatter annihilation-reactions"(if the adsorbed cosmic-dusts or gas-molecule or ion-flows are relatively few, it will sprayed directly the "meson-flow" out of the bottom spout to obtain thrusts that under the constraint of magnetic field.). The great bottom spout of the saucer-shaped spacecraft will mix the radiant energy of the antimatter/matter reaction with the thrust medium and spout out after heating and pressing to get the thrust, or will mix the radiant energy of the antimatter/matter reaction with the absorbed the gas when flying in the atmosphere and spout out after heating and pressing to get the downward thrust. This aspect of the thrust technology will be very important for the survival of the spacecraft. For the efficiency, safety,energy saving and maneuverability purposes, the highest speed of the saucer-shaped spacecraft flying in the solar system will be no morn than ten percent of the speed of light(even its cruising speed will be about one percent of the speed of light). And it will achieve the eceleration or stopping of flight useing the atmosphere and the ionosphere of the sun or the gaseous planets. And there will be a lot of space filling-stations/harbors in the ecliptic plane of the solar system, that it will achieve the deceleration or stopping of flight using a kind of nanometre-particles/aerogel structural magnetic-fluid's decelerating-orbit in safety.

The present equipments converting nuclear power into electric power are always too huge and too heavy, so it will not be suitable for fitting in the future miniature spacecraft, and will only be suitable for fitting in the future large-size spacecraft carrier, or will also be suitable for fitting in the future interstellar passenger/cargo spacecraft which emphasizing the energy efficiency and economical efficiency. Then the energy of the antimatter/matter reaction in the saucer-shaped spacecraft intend to be converted into electric power efficiently and expediently, that it will not do without the photoelectric effect electricity generation， thermoelectric effect electricity generation,hall effect electricity generation(magnetohydrodynamic electricity generation), and ram air turbine electricity generation； Among them, we want to solve the two problems of the three major problems about the antimatter-energy; Namely to realize the problem of storaging safely the large-mass and high-density antimatter, and the problem of emiting directionally and absorbing/converting safely the high-energy gamma-rays under manual-control; But here we will not involved the problem of the large-scale-manufacturing-technology of the antimatter. The first problem has been described earlier, we will confined the Superconducting-antimatter-metal-hydrogen(which will store large currents at the same time.) in the ultralow-temperature vacuum-loop-tubular by strong superconductor-magnetic-fields of the Loop-tubular storage-box of superconducting magnetic-levitation about antimatter; And the second problem will be solved in this power generator, namely the near-light-speed's meson-flows generated by the "positive and antimatter annihilation-reactions", which will been constrained and accelerated in a strong magnetic-fields similar to the Synchrotron-Radiation-Device, and them will generate and eventually convert all of themselfs into the gamma-rays, and these gamma-rays with the principle of "synchrotron radiation" has strong directivity or collimation, which will all impact on the "high-density radiation-resistant absorbing-material-layer of various power-generation-devices around them and the turbine-blades in turbogenerators", and that it will convert the gamma-rays-radiation from three-dimensional direction to two-dimensional direction through constraint and acceleration of the magnetic-fields, so to get more efficient generation and prevent all-directional radiation-damage of high-intensity gamma-rays. Perhaps the future efficiency of the compact-size energy conversion system will still reach more than fifty percent, but there will be a long time process to be explored.
