| Summary: | The purpose of this study is to develop a new muon beam monitor for MUon Science Innovative Channel (MUSIC) project at Osaka University. It was a prototype with the dimension of 20x20x1cm3 plastic scintillating counter with wavelength shifting fibers (WLS-Fi) readout to alternate the particle beam to the multi pixel photon counter (MPPC). We are using Strontium-90 as a test source along this research. The data was taken in 10000 events by varying parameters such as number of MPPCs used and the source positions. Raw data will be processed and plotted in a histogram. 12 MPPCs were used to determine light yield by MPPC. A maximum of 10 photons was detected by MPPC nearest to source. It is half of the estimated number of photon which is calculated using formula. Then, we add two photomultiplier tube (PMT) to trigger at opposite direction, we estimated the best position resolution is about 3mm for black sheet condition. As a conclusion, black sheet condition gives best resolution compare to other. |
