| Abstract: | Both DC current transformer(DCCT) and integrating current transformer(ICT) can be used in DC beam current measurement.The ICT has strong capability of resisting electromagnetic interference,but its measurement accuracy cannot satisfy the DC beam current measurement requirement when using traditional high speed A/D.With high resolution A/D and equivalent sampling system,DC beam current measuring system based on ICT can reach high accuracy compared with DCCT system.In this paper,the ICT-based DC beam current ... |
