Abstract

The BeEST experiment is a precision laboratory search for physics beyond the standard model that measures the electron capture decay of \(^7\)Be implanted into superconducting tunnel junction (STJ) detectors. For Phase-III of the experiment, we constructed a continuously sampling data acquisition system to extract pulse shape and timing information from 16 STJ pixels offline. Four additional pixels are read out with a fast list-mode digitizer, and one with a nuclear MCA already used in the earlier limit-setting phases of the experiment. We present the performance of the data acquisition system and discuss the relative advantages of the different digitizers.

BeEST实验三期数据采集系统

BeEST实验是一项精确的实验室研究，目的是超越标准模型，测量植入超导隧道结（STJ）探测器的\(^7\) Be的电子捕获衰变。在第三阶段的实验中，我们构建了一个连续采样数据采集系统，从16个STJ像素中离线提取脉冲形状和时序信息。四个额外的像素用快速列表模式数字化仪读出，一个核MCA已经在实验的早期极限设置阶段使用。介绍了数据采集系统的性能，并讨论了不同数字化设备的相对优势。
