Description
The Superconducting Array for Low Energy Radiation (SALER) experiment aims to search for BSM electroweak physics by precisely measuring the eV-scale recoiling nucleus following beta decay of short-lived neutron deficient nuclei. To do so, SALER couples a superconducting precision sensor array to the ReA3 beamline at the Facility for Rare Isotope Beams. During beam delivery, isotopes of interest are embedded in the sensors where the decay recoil energy can be measured with better than 10 eV FWHM resolution. This measurement technique has been demonstrated with success in the BeEST experiment with $^7$Be, and SALER extends the technique to isotopes with half lives potentially as short as 100 ms. This talk presents recent progress towards the commissioning of the experiment, demonstration of better than 2.5 eV FWHM electron recoil resolution, and prospects for measurements enabled by this experimental program.
