Abstract :
We demonstrate for the first time the capability of commercially available Ge-APDs to achieve single photon sensitivity and sub-nanosecond time resolution at 77K. The selection procedure of the samples both with a curve tracer and in pulsed operation is described in detail. Further improvements of the timing performance can be obtained by a suitable design of the devices.
