Abstract:
The technology of diamagnetic loop (DML) diagnosing intense pulse beam radius is a kind of on-line diagnostics. The technologies can diagnose beam emittance and obliquity on-line cooperating with other technologies such as three gradients method. In this paper, we introduce the theory of diamagnetic loop, design and calibrate diamagnetic loop device. And we diagnose the double pulse electron beams radius generated by the 2MeV injector. By the DML, the double beams radii are 6.84mm and 5.63mm, which are accordant with the results of a frame camera.
