Description
A vacuum insulated MeV accelerator, where the whole negative ion source and accelerator are immersed in vacuum, has been developed at JAERI for fusion application. The voltage holding of the accelerator was stable at 1 MV, which meets the requirement for International Thermonuclear Experimental Reactor (ITER). This was achieved by suppressing the electric field at triple junction of large FRP insulator columns of 1.8 m in diameter. This improvement enabled us to perform the high energy operation of the MeV accelerator. The H- ion current density at present was increased to be 146 A/m2 (accelerated H- current: 206 mA) at 836 keV. (author)
