基于MRPC技术的托盘飞行时间探测器参加了2003年STAR的p+p和d+Au碰撞物理运行。结合STAR实验的时间投影室（TPC）和伪顶点位置探测器（pVPD）的信息，进行校正以校准新原型TOF。 TOFr 的固有时间分辨率达到 85ps，并将 π/K 和 K/p 分离度分别扩展至 1.6GeV/c 和 3.0GeV/c。
A tray of Time of Flight detector based on MRPC technology took part in the physics run of STAR both in p+p and d+Au collisions in 2003. Together with the information from the Time Projection Chamber(TPC) and the pseudo-Vertex Position Detector (pVPD) of the STAR experiment,corrections are done to calibrate the new prototype TOF. The intrinsic time resolution of TOFr reaches 85ps and it extends the π/K and K/p separation up to 1.6GeV/c and 3.0GeV/c respectively.
