Design and performance of Hall probe measurement system in CSNS

Abstract

Background The construction of China Spallation Neutron Source (CSNS) was started in 2011 and will be completed in 2018. The phase I CSNS facility consists of an 80MeV HLinac, a 1.6GeV Proton Rapid Cycling Synchrotron (RCS), two beam transport lines and a target station. Magnets in the RCS and transport lines should be measured before being installed in the tunnel. Method In this paper, a new hall probe measurement system is described. The design and performance of the hall probe measurement system is presented. Conclusions The measurement results meet the design requirements. Some key issues were solved in the process.
