K. Deiters et al., Investigation of the avalanche photodiodes for the CMS electromagnetic calorimeter operated at high gain, NUCL INST A, 461(1-3), 2001, pp. 574-576
Avalanche Photodiodes (APD) with improved characteristics were developed by
Hamamatsu Photonics for the Electromagnetic Calorimeter of the CMS experim
ent. This report presents measurements of the latest generation of APDs, wh
ich are capable to operate at high gains (similar to 2000). (C) 2001 Publis
