3. Nuclear recoil detection with color centers in bulk lithium fluoride

Talk

We present initial results on nuclear recoil detection based on the fluorescence of color centers created by nuclear recoils in lithium fluoride. We use gamma rays, fast and thermal neutrons, and study the difference in responses they induce, showing that this type of detector is rather insensitive to gamma rays. We use light-sheet fluorescence microscopy to image nuclear recoil tracks from...

33. Testing the Gallium neutrino anomaly… with CEνNS?

Talk

The capability to perform precision measurements of nuclear form factors or coupling constants with CEνNS relies on a precise knowledge of the incoming neutrino flux and spectrum. Isotopes decaying via electron capture (EC) represent a close-to-ideal neutrino source, thanks to the monoenergetic spectrum and the possibility of precisely measuring the source activity. However, the low energy of...

Talk

The Migdal In Galactic Dark mAtter expLoration (MIGDAL) detector is a state-of-the-art low energy optical time projection chamber capable of resolving low dE/dx electrons alongside very high dE/dx nuclear recoils. The goal of this experiment is to make the first observation of the Migdal effect, a rare nuclear scattering process invoked to extend the sensitivity of dark matter experiments to...

58. CYGNUS and laying the groundwork for the directional detection of CEνNS

Michael Litke (University of Hawaii at Manoa)

Talk

The directions of low energy nuclear recoils open windows into previously unprobed areas of physics. Specifically, directional detection of coherent elastic neutrino nucleus scattering (CEνNS) would probe for new, beyond-the-standard-model (BSM) gauge bosons involved in that interaction as well as provide a tool for distinguishing between dark matter and neutrino scattering. Currently the only...

18. Calibrations and background simulations for the NEWS-G3 experiment

George Savvidis (Queen's University)

Talk

The NEWS-G3 experiment aims at the detection of reactor neutrinos using a 60cm-diameter Spherical Proportional Counter (SPC) at high pressure. The low energy threshold down to single-electron detection and the electron-counting capabilities, allow for the detection of low energy nuclear recoils, with an estimated event rate of 5 events/bar/day/GW in argon at 20m from the reactor core....
