Design and experiment of insulation support of 2MeV injector

Aiming at the technical request of high power injector, we designed two Nylon radial graded insulation supports on the heads of cathode and anode of the existing 2MeV injector. The experiment results showed that, on the basis of credible insulation, the supports improved the quality of coaxality between the cathode and the anode, ameliorated the identity of the three axes of beams, magnetic field and mechanism, and settled the groundwork for advancing each technical performances of the 2MeV injector.
