Abstract
The aim of this study is to characterize new prototype avalanche photodiode (APD) arrays for positron emission tomography (PET). Two different APD array prototypes developed by Radiation Monitoring Device (RMD) are investigated. Quantum efficiency of the APD is measured as a function of wavelength in the VIS-UV region. Capacitance is determined as a function of bias voltage. Dark current and gain are measured at fixed temperatures as a function of bias voltage. Finally, bulk and surface contributions to the dark current are estimated.
