The level-1 trigger for the SuperCDMS experiment at SNOLAB

https://doi.org/10.1088/1748-0221/17/07/P07010

Wilson, J.S.; Meyer zu Theenhausen, H.; von Krosigk, B.; Azadbakht, E.; Bunker, R.; Hall, J.; Hansen, S.; Hines, B.; Loer, B.; Olsen, J.T.; et al (July 2022, Journal of Instrumentation)

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.

Performance of a large area photon detector for rare event search applications

https://doi.org/10.1063/5.0032372

Fink, C_W; Watkins, S_L; Aramaki, T.; Brink, P_L; Camilleri, J.; Defay, X.; Ganjam, S.; Kolomensky, Yu_G; Mahapatra, R.; Mirabolfathi, N.; et al (January 2021, Applied Physics Letters)

We present the design and characterization of a large-area Cryogenic PhotoDetector designed for active particle identification in rare event searches, such as neutrinoless double beta decay and dark matter experiments. The detector consists of a 45.6 cm2 surface area by a 1-mm-thick 10.6 g Si wafer. It is instrumented with a distributed network of Quasiparticle-trap-assisted Electrothermal feedback Transition-edge sensors with superconducting critical temperature Tc=41.5 mK to measure athermal phonons released from interactions with photons. The detector is characterized and calibrated with a collimated 55Fe x-ray source incident on the center of the detector. The noise equivalent power is measured to be 1×10−17 W/Hz in a bandwidth of 2.7 kHz. The baseline energy resolution is measured to be σE=3.86±0.04 (stat.)−0.00+0.19 (syst.) eV. The detector also has an expected timing resolution of σt=2.3 μs for 5 σE events.

In this letter, we present the performance of a 100 μm × 400 μm × 40 nm W Transition-Edge Sensor with a critical temperature of 40 mK. This device has a noise equivalent power of 1.5×10-18 W/Hz, in a bandwidth of 2.6 kHz, indicating a resolution for Dirac delta energy depositions of 40 ± 5 meV (rms). The performance demonstrated by this device is a critical step toward developing a O(100) meV threshold athermal phonon detector for low-mass dark matter searches.
