Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

VIRTUAL INPA SEMINAR | Scott Kravitz (LBNL)

October 9, 2020 @ 12:00 pm - 1:00 pm

Speaker: Scott Kravitz (LBNL) 
 
Title: CrystaLiZe – Solid Xenon Detector R&D
 
Abstract: 
Radon and its daughter decays limit the sensitivity of direct WIMP dark matter searches, despite extensive screening programs, careful material selection and specialized Rn-reduction systems. For xenon time projection chambers, a means to surpass this constraint may lie in crystallizing the xenon. In a solid matrix, each of the decay steps surrounding the problematic radon daughter beta decay isotopes could be vetoed at the fixed position of the decay sequence. The constraint of time structure in the sequence could allow veto efficiency to approach 100%, with minimal effect on acceptance. In this case, the limiting background for WIMP searches would be neutrinos from the sun and from cosmic ray muons. It is additionally hypothesized that crystalline xenon may offer improved particle discrimination compared with liquid. In this talk, I will argue that an instrumental radon tag in a crystalline xenon TPC may be the quickest path to reaching the neutrino floor and present preliminary results from a test stand which suggest that solid Xe is a viable particle detection medium.
