In recent years, high sensitivity, low-threshold detectors employing transition edge sensor (TES) read out technology have garnered significant interest in the field of rare-event searches. Numerous experiments have incorporated these detectors for direct dark matter detection and coherent elastic neutrino-nucleus scattering (CEνNS) studies. As these experiments scale up and operate larger arrays, a key challenge is to enhance the reproducibility among detectors while promoting modularity in terms of both the choice of absorber and sensor. COSINUS (Cryogenic Observatory for SIgnals seen in Next-generation Underground Searches) has experimentally demonstrated that a novel cryogenic detector scheme, known as remoTES, can address these challenges. This contribution outlines findings from a systematic study of Si prototypes, highlighting ongoing optimization efforts to achieve better detector performance.

Abstract

In recent years, high sensitivity, low-threshold detectors employing transition edge sensor (TES) read out technology have garnered significant interest in the field of rare-event searches. Numerous experiments have incorporated these detectors for direct dark matter detection and coherent elastic neutrino-nucleus scattering (CEνNS) studies. As these experiments scale up and operate larger arrays, a key challenge is to enhance the reproducibility among detectors while promoting modularity in terms of both the choice of absorber and sensor. COSINUS (Cryogenic Observatory for SIgnals seen in Next-generation Underground Searches) has experimentally demonstrated that a novel cryogenic detector scheme, known as remoTES, can address these challenges. This contribution outlines findings from a systematic study of Si prototypes, highlighting ongoing optimization efforts to achieve better detector performance.
