Description
The Solenoidal Large Intensity Device (SoLID) at Jefferson Lab (JLab) uses Multi-gap Resistive Plate Chambers (MRPC) to identify kaons. SoLID requires 20ps for the total time resolution. In this paper, a sealed MRPC (sMRPC) prototype with 4 stack and 7 uniform gas gaps is designed to reach a good time resolution. At the same time sMRPC can lower the airflow through the chamber to reduce the greenhouse pollution. Both TDC and waveform sampling are used for the readout of the signal. In cosmic tests we compared the time resolution of these electronic readout method and researched how readout method affects the time resolution.
