    Abstract
  • IntroductionHPGe detector is used widely, its property is affected by neutron. Annealing to the germanium crystal is a good approach to recover the detector.
    PurposeTo raise the temperature of germanium crystal to recover the resolution for the HPGe detector.
    MethodA special copper ingot is designed and manufactured to increase the heating efficiency. Two temperature controlled power supplies are used to heat the germanium crystal and keep the temperature for cooling rod.
    ConclusionThe experiment results indicate that raising temperature to 70 ∘C for five days, the restoration efficiency is better than 90%.
