Description
The Mu2e experiment is constructing a calorimeter consisting of 1,348
un-doped CsI crystals in two disks. Each crystal has a dimension
of 34x34x200 mm$^3$, and is readout by a large area SiPM array. A
series of technical specifications on mechanical and optical
parameters was defined according to the calorimeter physics
requirements. Pre-production CsI crystals were procured from three
firms: Amcrys, St. Gobain and SICCAS. We report the quality
assurance on crystal's scintillation properties and their
radiation hardness against ionization dose and neutrons. The
results confirm that the quality of mass produced un-doped CsI
crystals in the market satisfies the Mu2e requirements.
