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.

Special INPA SEMINAR – Karthik Ramanathan (University of Chicago)

February 4 @ 11:00 am - 12:00 pm

Speaker: Karthik Ramanathan (University of Chicago)
Title: Dark Matter Taking Selfies: The DAMIC Experiment 
Abstract: The DAMIC (Dark Matter in CCDs) experiment uses silicon charge-coupled devices (CCDs), traditionally employed for imaging purposes, to detect potential ionization signals from dark matter interactions. These approx. mm thick devices feature an impressively low leakage current (< 10-21 A/cm2) and a very low energy threshold (40 eVee), making them ideal low-mass dark matter detectors. In addition, their unique spatial resolution provides for effective identification and mitigation of environmental backgrounds. In this talk, I will highlight recent dark matter-electron scattering limits from the experiment at SNOLAB, discuss the kg-size next generation DAMIC-M detector funded for operation, and show results from “Skipper”instrumented CCDs – a novel readout technique that allows for counting of individual charges, with a demonstrated resolution of 0.07 e-, which ushers in a new era of sensitivity to low-energy interactions.

Sessler Conference Room CA + Google Map

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.
