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] Speaker: Alec Lindman (University of Mainz) Title: Atomic tritium for next-generation neutrino mass measurement with Project 8

February 15 @ 12:00 pm - 1:00 pm


Date:  Thursday, February 15, 2024

Time: 12:00 PM – 1:00 PM

Location: Sessler Conference Room–50A-5132 [Hybrid and In-Person]

Speaker: Alec Lindman (University of Mainz)

Title: Atomic tritium for next-generation neutrino mass measurement with Project 8

Abstract: Neutrinos provide a window to physics beyond the Standard Model through their nonzero mass, but new technology is required to push below current limits. Project 8 is a next-generation direct neutrino mass experiment with a sensitivity of 40 meV/c^2. We have established a new frequency-based technique, cyclotron radiation emission spectroscopy (CRES), to make precise, differential measurements of the endpoint region of the tritium beta-decay spectrum. Atomic tritium will improve Project 8’s sensitivity by 10 to 30 times over a similar molecular experiment. This talk will focus on the development of the new technologies to enable the atomic tritium experiment. I will outline Project 8’s atomic architecture, which includes large magnetic traps (~ 50 m^3) that store atoms at ~ 1 mK to benefit from CRES’s volume scaling, a chain of atom cooling and transport elements to maintain the intended density in the trap, and a tritium-compatible atom source that can provide the necessary flux of 10^19 atoms/s.

February 15
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)
