基于多间隙电阻板室（MRPC）技术，研制了一种用于HIRFL-CSR外靶实验（埃特）的T0/Trigger探测器。它测量重离子碰撞中产生的粒子在目标区域的多重性和时间信息，提供必要的事件碰撞时间（T0）和碰撞中心性与高精度。蒙特-卡罗模拟表明，在中心碰撞时，可以获得几十皮秒的时间分辨率。在CSR-ETE上对该原型探测器进行了实验测试。初步的结果显示，以证明T0/触发器检测器的性能。
A new T0/Trigger detector based on multi-gap resistive plate chamber (MRPC) technology has been constructed and tested for the external target experiment (ETE) at HIRFL-CSR. It measures the multiplicity and timing information of particles produced in heavy-ion collisions at the target region, providing necessary event collision time (T0) and collision centrality with high precision. Monte-Carlo simulation shows a time resolution of several tens of picosecond can be achieved at central collisions. The experimental tests have been performed for this prototype detector at the CSR-ETE. The preliminary results are shown to demonstrate the performance of the T0/Trigger detector.
