Abstract :
A compact and fast electromagnetic calorimeter prototype was designed, built, and tested in preparation for a next-generation, high-rate muon ( g − 2 ) experiment. It uses a simple assembly procedure: alternating layers of 0.5-mm-thick tungsten plates and 0.5-mm-diameter plastic scintillating fiber ribbons. This geometry leads to a detector having a calculated radiation length of 0.69 cm, a Molière radius of 1.73 cm, and a measured intrinsic sampling resolution term of ( 11.8 ± 1.1 ) % / E ( GeV ) , in the range 1.5–3.5 GeV. The construction procedure, test beam results, and GEANT-4 comparative simulations are described.
