摘要:

我们目前的结果准扩散研究大,3英寸直径,1英寸厚[100]高纯度锗晶体,在真空中的稀释冰箱冷却到50 mK,并暴露于59.5 keV的γ射线从Am-241校准源。我们比较了在两种不同的探测器类型,不同的声子传感器面积覆盖范围,从Monte Carlo的结果得到的数据。蒙特卡罗包括声子准扩散和由载流子产生的声子的产生,因为它们通过电离读出通道在检测器上漂移。

英文摘要:

We present results on quasidiffusion studies in large, 3 inch diameter, 1 inch thick [100] high purity germanium crystals, cooled to 50 mK in the vacuum of a dilution refrigerator, and exposed with 59.5 keV gamma-rays from an Am-241 calibration source. We compare data obtained in two different detector types, with different phonon sensor area coverage, with results from a Monte Carlo. The Monte Carlo includes phonon quasidiffusion and the generation of phonons created by charge carriers as they are drifted across the detector by ionization readout channels.
