Development of Large-Area Charged Particle Detector with Inorganic Scintillator Plates and Wavelength Shifting Fibers
Published online: 10 January 2018
A Large-area charged particle detector for highenergy physics experiments has been developed. This detector includes inorganic scintillator plates with thicknesses of 0.5 mm and wavelength-shifting fibers (WLSFs) of 0.2 mm in diameters. The size of effective area is 1 m by 1 m. The WLSFs are connected to both plate surfaces optically, and on the top and the bottom, fibers are attached along to x and y-axis direction, respectively. The best WLSF to obtain large number of photoelectrons is determined, which enables us to detect charged particles with thinner scintillation crystals. This means an improvement of position resolution of this detector. The number of photoelectrons obtained from a new type scintillation crystal, which is more reasonable than the conventional ones are also measured. We also estimated its position resolution. This detector enables us to detect charged particles with higher position resolution and lower cost than conventional scintillation detectors and gas chambers.
