About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

VIRTUAL INPA SEMINAR | Kelly Stifter (Stanford)

January 8 @ 12:00 pm - 1:00 pm

Speaker: Kelly Stifter (Stanford University)

Title: The LZ Dark Matter Experiment: From Detector Development to First Physics

Abstract:

LZ is a next generation dark matter search designed to significantly extend our sensitivity to WIMP dark matter candidates. At the core of the LZ experiment is a dual-phase xenon time projection chamber (TPC) with a 7 ton active mass. The detector has been assembled at the Sanford Underground Research Facility (SURF) in Lead, South Dakota and is now in the commissioning phase. After 1000 days of live time, LZ will achieve a sensitivity of about 1.4 x 10-48 cm2 at 40 GeV/c2 WIMP mass, improving on previous results by over an order of magnitude. In this talk, I will give an overview of the development, construction, and current commissioning status of the experiment, focusing in particular on the liquid xenon detector at the core of LZ. I will highlight the design and implementation of key features that drive the sensitivity of the experiment, including scintillation and ionization detection thresholds and control of backgrounds.

INPA guests from campus can now come up to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 am to 12:00 noon, and from 1 pm to 5 pm. Note that the seminars are now held in 50A-5132 to accommodate a larger number of attendees.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.
