Diamagnetic Loop Diagnostic Intense Pulsed Electron Beam Radius

Beam diagnostic devices including beam position, beam magnitude and beam radius diagnostic devices is widely used in Linear Induction Accelerator(LIA).Diamagnetic loop is new beam diagnostic technology, it measures electromagnetic parameter-magetic moment that is brought while beam is transforming, by measuring magnetic moment we can calculate beam radius. Diamagnetic loop is non-intrusive diagnostic system, it can diagnose beam radius on line and it can diagnose beam emittance and obliquity cooperating with other technology such as three gradient method and beam bugs. Diamagnetic loop has many merits like simple machinery, anti electromagnetic jam and convenient use,etc. So we want to apply Diamagnetic loop in LIA, it will be significative.In this paper, we have studied the feasibility for Diamagnetic loop to be used in LIA. On the base of the academic study, we have designed and set up the experimental facilities that can be used to generate the high current pulse simulating beam of LIA. The diamagnetic loop experiments and calibrations have done on the experimental facilities. The results of the experiment show that the diamagnetic loop can revert beam waveform, the signal on the diamagnetic loop is very high, we can use it conveniently.It is the first time to study the feasibility for diamagnetic loop to use in LIA in China.
