Large Area APD-readout of LYSO crystals — •Helena Nowak — GSI Darmstadt

For the first time the novel LYSO crystals with sizes of 10x10x10 mm^3 and 20x20x200 mm^3 have been read out with a Large Area APD (LAAPD).

LAAPDs with dimensions of 10x10 mm^2 represent the envisaged photo device of the electromagnetic calorimeter of the PANDA detector.

LYSO offers high density, high light output and excellent energy resolution (measured with PMTs) compared to materials with similar density (BGO). The properties and the results of the readout with LAAPDs will be presented.
