摘要:

本文建立了一个用于无中微子双β衰变实验的大晶体探测器中热流的简单热模型。探测器由CaMoO $_{4}$晶体和金属磁量热计(MMC)组成。吸收体和传感器之间的热连接由蒸发在晶体表面上的金膜和连接到该膜和MMC传感器的金键合线组成。该模型描述了金膜上热流的非热过程和热过程。基于金膜面积和厚度的优化计算的连续实验显示出测量信号的大小和上升时间的显着改善。

英文摘要:

We established a simple thermal model of the heat flow in a large crystal detector designed for a neutrinoless double beta decay experiment. The detector is composed of a CaMoO$_{4}$ crystal and a metallic magnetic calorimeter (MMC). The thermal connection between the absorber and the sensor consists of a gold film evaporated on the crystal surface and gold bonding wires attached to this film and the MMC sensor. The model describes athermal and thermal processes of heat flow to the gold film. A successive experiment based on optimization calculations of the area and thickness of the gold film showed a significant improvement in the size and rise-time of the measured signals.
