Description
In the last year, SuperCDMS has demonstrated multiple detectors with <3 eV resolution with masses from 0.25 to 10g, and we are operating multiple prototype detectors which we expect to achieve sub-eV resolutions. This is the result of an R&D program to fabricate low-Tc TES readout and improve energy collection efficiency of our devices. In addition, a subset of these detectors has demonstrated <0.01 electron resolution using the NTL voltage gain method at a bias voltage of 250V. I will present these recent results, and discuss the path forward for our R&D program to achieve sub-eV thresholds (resolutions around 100-200 meV) in the near future, as well as the science prospects of running these devices in our low-background underground test facilities, NEXUS and CUTE. I will also talk about the work we're putting in to port our sensor technology from Si to lighter targets, including diamond, SiC, and sapphire (Al2O3), useful for enhanced sensitivity to low-mass particles, and greater radiation hardness.
