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 – Hao Chen (Texas A&M University)

July 17 @ 12:00 pm - 1:00 pm

Speaker: Hao Chen (Texas A&M University)

Title: Two New Cryogenic Detector R&D

Abstract: It is well-accepted that the majority of the matter in the universe is dark and non-baryonic. The nature of dark matter, however, remains mysterious. Various proposed candidates span a wide range in the mass and cross section parameter space. Many experimental efforts have been made aiming to detect dark matter particles directly, part of the region in the parameter space has been excluded from their data. Probing the lower mass region requires a low threshold detection technique. I will talk about two new cryogenic detectors that are currently under development. The magnetic bubble chamber utilizes a single-molecule magnet as the target, amplifying the signal from a scattering event by magnetic avalanches. The phonon-mediated high-voltage detector combines features of CDMS iZip and HV detector, provides a possible way to achieve a low threshold without losing the electron recoil/nuclear recoil discrimination.

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.
