HL-2A中多路分时积分器的研制

Multi-channel time-division integrator in HL-2A

中国环流器二号A装置(HL-2A)是我国第一个具有偏滤器位形的托卡马克装置,利用其极向偏滤器在高参数等离子体条件下开展与偏滤器位形运行有关的研究。直观的观测核放射过程中核脉冲信号随放射时间的强弱变化规律对于掌握受控核聚变有着重大的意义。我们为HL-2A装置研制的多路分时积分器具有自动削掉输入信号的负向反脉冲,积分时间0.2～1ms五档可调,统一起始TTL触发脉冲,20s自动定时工作,同时有十路信号积分的特点。

HL-2A is China＇s first Tokamak device with divertor configuration （magnetic confinement controlled nuclear 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.
