On the choice of optimal parameters for a fast atom injector

The present investigation deals with optimization of imitation model of hydrogen (deuterium) fast atoms injector ensuring energy input into the thermonuclear reactor plasma. The injection scheme with recharge of fast positive ions is considered. As optimicability criterion the function determining energy costs for power unit introduced into the reactor is used. The injection system comprises a number of elements: ion source with a gas discharge chamber neutralizer separator ion receptor atom caloriqeter-receptor atomguide and cryogenic vacuum chamber. The analysis of structural scheme of the injector imitation model has shown that output parameters of one group of modules are input parameters for calculation of the other. The initial investigations are carried out at three variable values: relation of initial geometric beam dimensions, neutralizer length and total area of cryopanels
