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 | Walter Pettus (Indiana University)

April 16 @ 12:00 pm - 1:00 pm

Speaker: Walter Pettus (Indiana University Bloomington)

Title: Project 8: Towards the Atomic Tritium Future of Direct Neutrino Mass Measurement


Neutrino flavor oscillations provided the first break in the Standard Model by proving that neutrinos have nonzero mass, but leave us with an unanswered question: How much mass?  Project 8 is a next-generation experiment based on the novel Cyclotron Radiation Emission Spectroscopy (CRES) technique to perform a radio frequency-based measurement of the tritium beta spectrum.  The goal of the phased program is to reach a mass sensitivity below 40 meV, completely covering the allowed region of the inverted mass ordering. In this talk, I will present results from the waveguide apparatus measurements of 83mKr and molecular tritium, demonstrating the capabilities of the CRES technique.  Progress is underway on the next phase of the experiment focusing on a pair of critical technology demonstrations – scaling the CRES technique to a large free-space volume, and production and trapping of a high-intensity atomic tritium source.

April 16
12:00 pm - 1:00 pm

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.

INPA Common Room (50-5026)
3:30 pm

Access to the Lab

For a shuttle pass please email Paris Gordon. Please note: the pass is only valid for the day of the seminar.
