Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

[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.
