Abstract: In fusion experiments, integrator is a fundamental method to recover differential signals, and the 
development of low drift integrator system is an important step in tokamak experiment. A low drift integrator 
system for magnetic measurement on HL-2M tokamak is introduced. By means of analog and digital 
compensation, the drift is reduced and the measurement accuracy between signals is improved. The performance 
test shows that the output drift of the integrator is less than 2mV/15s, and the accuracy of the integral time 
constant is better than 0.3%. The integrator is applied to HL-2M tokamak experiments and meets the requirements 
of magnetic measurement system. 

Key words: HL-2M tokamak, Integrator, Magnetic measurement
