Abstract

In this paper, development of large area planar APDs and monolithic APD arrays for scintillation detection is discussed. Single APDs with area as large as 10 cm2 have been fabricated and tested with CsI(Tl) scintillator (3.8 cm diameter, 2.5 cm high). The resolution of the 662 keV photopeak has been measured to be 9% (FWHM). Multi-element APD arrays have also been fabricated in various formats such as 4/spl times/4 to 14/spl times/14 elements (2 mm pixels) and their gain, noise and dark current performance has been characterized. Scintillation and timing studies have also been performed by coupling these arrays to LSO and CsI(Tl) scintillators. Packaging, and electronic readout issues related to these APD devices are discussed.
