  • Department of Engineering Physics,Tsinghua University,Beijing 100084,China2 Institute of Fluid Physics,CAEP,Mianyang 621900,China

  • The three gradient method is a conventional means for beam emittance measurement. In intense electron beam accelerators,since the space charge effect is remarkable, the conventional three gradient method in not available.A MTGM(abbreviation for the Modified Three Gradient Method)is an improvement of the conventional three gradient method, the space charge effect is included in this method. In this paper, the basic theory of MTGM is stated, the principle of applying the MTGM method to beam diagnostics is described. Experiments are carried out on two electron beams of 3.5MeV, 2.6kA, 100ns and 18MeV,2.6kA 100ns separately, which scheme is presented. Results of these experiments are presented together with the error analysis. The results show that the MTGM method is an effective way of emittance measurement for intense pulse electron beam.

      Abstract:The three gradient method is a conventional means for beam emittance measurement. In intense electron beam accelerators,since the space charge effect is remarkable, the conventional three gradient method in not available.A MTGM(abbreviation for the Modified Three Gradient Method)is an improvement of the conventional three gradient method, the space charge effect is included in this method. In this paper, the basic theory of MTGM is stated, the principle of applying the MTGM method to beam diagnostics is described. Experiments are carried out on two electron beams of 3.5MeV, 2.6kA, 100ns and 18MeV,2.6kA 100ns separately, which scheme is presented. Results of these experiments are presented together with the error analysis. The results show that the MTGM method is an effective way of emittance measurement for intense pulse electron beam.
