论文摘要
使用商业模块CAEN V2495设计的一般功能的触发系统用于费米能量的重离子核反应实验。该系统已在Cshine上应用和验证（重离子实验的紧凑型光谱仪）。基于命令寄存器访问和远程计算机控制操作的字段可编程逻辑门数组（FPGA）技术，可以根据实验物理目标灵活配置触发功能。使用Cshine上的触发系统，我们在Lanzhou（Ribll1）的放射性离子束线1上进行了25 MEV/U $ ^{86} {\ rm kr}+ ^{\ rm kr}+ ^{124} {\ rm sn} $。在线结果表明触发系统正常工作。该系统可以扩展到其他实验。
A trigger system of general function is designed using the commercial module CAEN V2495 for heavy ion nuclear reaction experiment at Fermi energies. The system has been applied and verified on CSHINE (Compact Spectrometer for Heavy IoN Experiment). Based on the field programmable logic gate array (FPGA) technology of command register access and remote computer control operation, trigger functions can be flexibly configured according to the experimental physical goals. Using the trigger system on CSHINE, we carried out the beam experiment of 25 MeV/u $ ^{86}{\rm Kr}+ ^{124}{\rm Sn}$ on the Radioactive Ion Beam Line 1 in Lanzhou (RIBLL1), China. The online results demonstrate that the trigger system works normally and correctly. The system can be extended to other experiments.
