Abstract

The CRESST experiment is designed to search for weakly interacting massive particle dark matter with cryogenic detectors. CRESST II will use up to 33 CaWO(4) crystals with a total mass of approximately 10 kg. These many detectors require a readout system based on 66-channel superconducting quantum interference devices (SQUIDs). In this article we report on the development of a modular superconducting connector for the 66-channel SQUID readout circuit. We show that the technique developed reliably produces superconducting contacts.

摘要

CRESST实验旨在利用低温探测器寻找弱相互作用大质量粒子暗物质。CRESST II将使用多达33块CaWO(4)晶体，总质量约为10千克。这么多探测器需要一个基于66通道超导量子干涉装置（SQUID）的读出系统。在本文中，我们报告了一种用于66通道SQUID读出电路的模块化超导连接器的开发情况。我们表明，所开发的技术能够可靠地产生超导接触。
