A heat pipe is provided in thermal contact with the target and has a housing portion with an exterior surface supporting the plurality of electronic components of the high voltage power supply. Heat pipe includes wick and heat transfer fluid disposed within the housing portion. The wick for recirculates the heat transfer fluid within the housing portion in order to transfer heat away from the target preferably to the bulkhead for dissipation the system housing. Both the wick and heat transfer fluid are preferably realized from materials that have low electrical conductivity. The heat pipe can also be part of other-type particle accelerators, such as x-ray sources and gamma-ray sources.11-07-2013

20110044418LONG LIFE HIGH EFFICIENCY NEUTRON GENERATOR - The design of a compact, high-efficiency, high-flux capable compact-accelerator fusion neutron generator (FNG) is discussed. FNG's can be used in a variety of industrial analysis applications to replace the use of radioisotopes which pose higher risks to both the end user and national security. High efficiency, long lifetime, and high power-handling capability are achieved though innovative target materials and ion source technology. The device can be scaled up for neutron radiography applications, or down for borehole analysis or other compact applications. Advanced technologies such as custom neutron output energy spectrum, pulsing, and associated particle imaging can be incorporated.02-24-2011

20110216866Method and apparatus for the production of nuclear fusion - By firing ionized reactant particles into a solid block of reactant, fusion reactions occur. As these particles are fired longitudinally into a thin sheet of reactant, fusion products are ejected laterally into a series of charged collectors. Unfused reactant ions that prematurely exit the solid reactant are recirculated by electric fields within the invention, boosting efficiency. Through the use of several collectors, charged particles of many energies are efficiently collected and converted to electric potential. The use of a solid sheet of reactant greatly increases the probability of fusion events taking place. The shape of the sheet acts to isolate the incoming reactant ions from the outgoing fusion products. Fusion products are not generally converted to heat by virtue of the small amount of material present in a typical product trajectory. Singly and together, these improvements act to greatly increase the efficiency of the reactor over prior art.09-08-2011
20160078973ALFVEN-WAVE GYRATING NON-LINEAR INERTIAL-CONFINEMENT REACTOR - A fusion reactor includes an improved ability to modulate a plasma for specific purposes. The reactor operates on the ability to change at least four separate variables in each of a plurality of lenses that are independent of the other lenses. This allows for the generation of Alfvén waves and modulation of the internal plasma dynamics, actively leading to higher states of efficiency. By combining modulation of a plasma in the form of an ion beam with a solid state metal target, an efficient fast neutron source can be produced. This can lead to industrial applications such as energy generation, nuclear clean-up, the production of rare earth metals out of semi-rare ones, and helium production.03-17-2016
