Bn. Kalinin et al., THE INVESTIGATION OF A MODEL OF AN EM CALORIMETER ON NABI(WO4)(2) CRYSTALS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 361(1-2), 1995, pp. 157-160
We have constructed a mock-up model consisting of nine elements to eva
luate the space and energy resolution of the NaBi(WO4)(2) crystal elec
tromagnetic calorimeter. The characteristics of the mock-up model have
been studied with a 700 MeV electron beam. It is shown that with cell
dimensions of about 2.4 cm one can achieve an accuracy of < 4 mm in m
easuring the coordinates. The investigations have shown that the calor
imeter has fast operation, satisfactory energy resolution and good spa
ce resolution characteristics.
