HL-2A is China’s first Tokamak device with divertor configuration(magnetic confinement controlled nu-clear fusion device).To find out the details of on-going fusion reaction at different times is of important significance in achieving controlled nuclear fusion.We developed a new type multi-channel time-division integrator for HL-2A.It has functions of automatic cutting off negative pulse of the input signals

optional integrating time division spacing 0.2～1 ms

TTL starting trigger signal

automatic regularly work 20 s

and integrating 10 channel at the same time.
