An improved 3He nuclear reactor with provision for direct electric conversion of a relativistic proton stream into useable electric power at a voltage level compatible with the national power grid (one million V DC). Various embodiments include multiple collector cages for extracting relativistic protons of various energy levels, diverter wires for deflecting high-energy proton streams to either side of lower energy cages to avoid unwanted impact. Other embodiments include arrangements for dividing multi-megavolt voltages down to a useable one megavolt level compatible with the national power grid. Further embodiments comprise guiding the proton stream by the cusps of magnetron cavities to permit conversion of the relativistic proton energies into microwave power. A proposal is also made for harvesting 3He from the Moon to supply earth-bound and space-bound reactors. A solution to the problem of charging a potential well-forming anode in an electrostatic fusion reactor without electrical arcing is further disclosed.

The invention relates to a method for improving the electrical properties of an AlGaN / GaN HEMT (High-Electron-Mobility Transistor) device. The method comprises the step of carrying out proton irradiation on the AlGaN / GaN HEMT device under the condition of a preset irradiation temperature, proton fluence and proton energy. By use of the embodiment of the invention, the protons of certain fluence and energy can be adopted to carry out irradiation on the AlGaN / GaN HEMT device, incoming protons can make up inherent defects in the device so as to reduce defect density, the capture of defects on a current carrier is lowered, electric density is increased, grid leakage current is reduced, the maximum saturation current and transconductance of the device can be improved, and therefore, the electric performance of the device is improved.

The invention discloses a method for inversing a radiation source, which is to measure a PDD curve by a water tank or other radiation dosimetry measuring equipment. Information of the high accuracy radiation source can be acquired by the method, including photon energy spectrum, or proton energy spectrum, or electron energy spectrum and photon pollution and other radiation information. The methodhas the advantages that: the information of the photon energy spectrum, the electron energy spectrum, the proton energy spectrum, photon pollution and other radiation source information of the radiation source can be simultaneously reestablished; the defect that the prior energy spectrum calculation method can not accurately acquire multiple radiation source information can be overcome; while theaccurate energy spectrum of the radiation source is accurately acquired, the information of the photon pollution and other information can be acquired; correct information of the radiation source canbe provided for dose calculation; information of scattered or continuous energy spectrum and the photon pollution can be acquired; and the accurate radiation source can be realized by a plurality of algorithms so as to solve the problem that the prior single algorithm can not ensure that the inverse of the energy spectrum has a solution.
