The level-1 trigger for the SuperCDMS experiment at SNOLAB

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.

Light dark matter constraints from SuperCDMS HVeV detectors operated underground with an anticoincidence event selection

https://doi.org/10.1103/PhysRevD.111.012006

Albakry, M F; Alkhatib, I; Alonso-González, D; Amaral, D_W P; Anczarski, J; Aralis, T; Aramaki, T; Arnquist, I J; Ataee_Langroudy, I; Azadbakht, E; et al (January 2025, Physical Review D)

This article presents constraints on dark-matter-electron interactions obtained from the first underground data-taking campaign with multiple SuperCDMS HVeV detectors operated in the same housing. An exposure of $7.63 g − days$ is used to set upper limits on the dark-matter-electron scattering cross section for dark matter masses between 0.5 and $1000 MeV / c^{2}$ , as well as upper limits on dark photon kinetic mixing and axionlike particle axioelectric coupling for masses between 1.2 and $23.3 eV / c^{2}$ . Compared to an earlier HVeV search, sensitivity was improved as a result of an increased overburden of 225 meters of water equivalent, an anticoincidence event selection, and better pile-up rejection. In the case of dark-matter-electron scattering via a heavy mediator, an improvement by up to a factor of 25 in cross section sensitivity was achieved. Published by the American Physical Society2025
