Fast spectrometer on the base of industrial Ge(Li) detector

An industrial sample of the DGDK type Ge(Li)-detector with one open end, with capacitive detector-preamplifier communication has been used as #betta#-spectrometer capable of operation under the conditions of large background loadings and having a rather high energy resolution. A plastic scintillation counter has been included in the scheme of fast coincidences. The obtained dependences of time and energy resolutions on loadings point out slight worsening of #betta#-spectrometer characteristics up to 105 pul./s loadings that provides its use in the experiments in accelerators at this level of loadings
