LHAASO将在海拔4410米处1平方公里的区域内铺设5242个电磁粒子探测器（ED）。艾德将用于探测能量范围为10 - 100 TeV的初级宇宙射线和γ射线产生的大范围空气簇射中次级电磁粒子的到达时间和粒子数密度。本文主要介绍艾德的定型设计，包括结构设计、长期稳定性和一致性设计，以及批量生产的检测结果。
LHAASO will lay 5242 electromagnetic particle detectors (EDs) in an area of 1 square kilometer above sea level at 4410m. ED will be used to detect the arrival time and particle number density of secondary electromagnetic particles in the extensive air showers which are generated by the primary cosmic rays and gamma rays with an energy range from 10TeV to 100PeV. This paper mainly introduces the finalized design of ED, including the design of structures, long-term stability and consistency, as well as the test results of EDs built in batches.
