SuperCDMS SNOLAB暗物质搜索实验旨在对低至0 (1ev)的能量沉积敏感。这对触发系统的分辨率、信号效率和噪声抑制提出了要求。为了实现这一点,SuperCDMS 1级触发系统在定制PCB上的FPGA中实现。时域最优滤波算法实现为有限脉冲响应滤波器,在典型噪声条件下,基线分辨率为噪声标准差σ n的0.38倍,信号幅值为1.1 σ n时触发效率为99.9%。灵活的触发器逻辑嵌入在模块化架构中,可以在各种目的和运行条件下以无死时间的方式可靠地触发和否决。本文将详细介绍触发器的体系结构和性能。
The SuperCDMS SNOLAB dark matter search experiment aims to be sensitive to energy depositions down to Script O (1 eV). This imposes requirements on the resolution, signal efficiency, and noise rejection of the trigger system. To accomplish this, the SuperCDMS level-1 trigger system is implemented in an FPGA on a custom PCB. A time-domain optimal filter algorithm realized as a finite impulse response filter provides a baseline resolution of 0.38 times the standard deviation of the noise, σ n, and a 99.9% trigger efficiency for signal amplitudes of 1.1 σ n in typical noise conditions. Embedded in a modular architecture, flexible trigger logic enables reliable triggering and vetoing in a dead-time-free manner for a variety of purposes and run conditions. The trigger architecture and performance are detailed in this article.
