| Research Abstract |
In elementary particle physics experiments, scintillating-tile and fiber calorimeters are used to measure the energies of daughter particles produced in collisions of high-energy particles. This device generates a light pulse whose size is proportional to the energy of the incident particle. In this research, we could successfully improve the energy resolution of the calorimeter by using the avalanche photodiodes (APDs) as photosensors for the calorimeter, instead of photomultiplier tubes generally used for calorimeters.
