摘要
An automatic gain-matching method has been developed for the energy calibrations of the 32 segments of a large-volume germanium detector. The method calibrates the small-volume segments relative to the central contact, which collects the charge from the total germanium crystal volume and can be efficiently calibrated with known sources. The method presented here can employ photons of arbitrary energy. With the use of in-beam gamma-rays for segment calibrations it presents an efficient way to perform continuous energy calibrations in experiments. (C) 2002 Elsevier Science B.V. All rights reserved.
