104. Beyond the BeEST: SALER

Andrew Marino (Colorado School of Mines)

2025-05-15, 1:30 p.m.

Oral invited talk

The SALER experiment aims to expand the precision nuclear recoil measurements in STJs pioneered by the BeEST to much shorter-lived isotopes on-line at FRIB. In this talk we present on the initial commissioning of SALER with a 262 nm UV laser as well as development towards coupling STJs in an ADR cryostat to the FRIB beamline.

135. ASGARD: Precision spectroscopy of short-lived isotopes

Leendert Hayen (LPC Caen)

2025-05-15, 1:50 p.m.

Oral invited talk

We will introduce the proposed ASGARD experiment, which utilises a combination of novel technological steps to perform high precision spectroscopy on short-lived isotopes. The latter is used for TeV-scale searches for new physics and can open up new directions in nuclear physics studies.

111. Beyond the BeEST: Optomechanical Sensing

David Moore (Yale)

2025-05-15, 2:10 p.m.

Oral invited talk

I will describe ideas to use optically trapped nanoparticles to search for sterile neutrinos or other new physics by directly measuring the momentum of nuclear recoils from the decay of radioisotopes within the particles. These techniques can provide complementarity to the energy resolving measurements performed by the BeEST, and can allow a number of isotopes to be studied.

127. Feasibility studies for low-mass dark matter searches

Pietro Giampa (TRIUMF)

2025-05-15, 2:30 p.m.

Oral contributed talk

In this talk, we will review why low-mass (KeV-MeV) dark matter is an interesting field of study and how cryogenic superconducting techniques could assist in the search for this elusive component of the universe.
