Abstract:
The SuperCDMS SNOLAB dark matter search experiment aims to
be sensitive to energy depositions down to 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.
