Description

Multigap Resistive Plate Chambers (MRPCs) are gaseous detectors being used worldwide in high energy physics experiments for charged particle detection. MRPCs are the advanced form of RPCs. RPCs are known to have good time resolution (~1 ns). In order to get even better time resolution, MRPCs were developed. The MRPCs used in experiments are made up of glass electrodes. We have taken an attempt to develop MRPCs using bakelite electrodes. Bakelite sheets of 500 μm thickness, procured from local market, were used to develop the 6-gap MRPC. The dimensions of the developed MRPC is 15 cm x 15 cm having each gas gap of 250 μm. The developed MRPC was tested for its various parameters like I-V test, efficiency, current stability, noise rate, time resolution with cosmic rays. The method of fabrication and test results of the MRPC will be presented.
