Methods for Сalibrating Half-Sectors of the MPD/NICA Electromagnetic Calorimeter Using Cosmic Ray Muons
摘要
Abstract
The 60-ton cylindrical electromagnetic calorimeter of the MPD facility of the NICA project with a diameter of 3.45 m and a length of 6 m under construction is assembled from 50 half-sectors, each containing 768 “Shashlik” towers of different sizes and different spatial orientations. The paper proposes methods for calibrating half-sector towers using cosmic muons passing both along and across the axes of the towers. The results of testing these methods on the first manufactured half-sector are presented.
