Research Abstract |
Multi Pixel Photon Counters (MPPC) are added to a long-size sandwich-type gamma detector, which is read out with wavelength shifting fiber (WLSF), to get high time resolution. From the beam experiment, good time resolution pre-amplifiers are needed to read MPPCs for the present time. We measured position dependencies of the light yield of WLSF. From the results, we established reconstruct particle position from light yields of WLSFs. Attenuation lengths of 3 kinds of WLSFs were measured. We selected best fibers for the detector, and basic parameters were got to make a new detector.
