摘要:

DarkSide-50实验是在Gran Sasso的Nazionali实验室进行的,它使用一个双相时间投影室,以50公斤低放射性氩作为目标,寻找暗物质。来自氩中相互作用的光信号由38个光电倍增管(PMT)的系统检测,其中19个在氩低温恒温器内的TPC体积上方,19个在氩低温恒温器内的TPC体积下方。我们描述了处理来自光电倍增器的信号的电子设备,识别感兴趣的事件的触发系统,以及记录数据以供进一步分析的数据采集系统。电子设备包括PMT上的电阻分压器、直接安装在液氩中PMT分压器上的定制前置放大器以及定制放大器/鉴别器(室温下)。光电倍增管信号经放大后在CAEN波形数字化器中数字化,用CAEN逻辑模块构成触发器,TPC的数据采集系统基于Fermilab的artmilling软件。该系统自2014年初开始运行。

英文摘要:

The DarkSide-50 experiment at the Laboratori Nazionali del Gran Sasso is a search for dark matter using a dual phase time projection chamber with 50 kg of low radioactivity argon as target. Light signals from interactions in the argon are detected by a system of 38 photo-multiplier tubes (PMTs), 19 above and 19 below the TPC volume inside the argon cryostat. We describe the electronics which processes the signals from the photo-multipliers, the trigger system which identifies events of interest, and the data-acquisition system which records the data for further analysis. The electronics include resistive voltage dividers on the PMTs, custom pre-amplifiers mounted directly on the PMT voltage dividers in the liquid argon, and custom amplifier/discriminators (at room temperature). After amplification, the PMT signals are digitized in CAEN waveform digitizers, and CAEN logic modules are used to construct the trigger, the data acquisition system for the TPC is based on the Fermilab "artdaq" software. The system has been in operation since early 2014.
