# Project 8 detector upgrades for a tritium beta decay spectrum using cyclotron radiation

## TL;DR

Project 8 is upgrading its detector to measure the tritium beta decay spectrum via cyclotron radiation, aiming to directly determine neutrino mass with recent progress on a new gas cell and experimental plans.

## Contribution

This work presents new detector upgrades and a gas cell development crucial for measuring the tritium beta decay spectrum in Project 8.

## Key findings

- Successful development of a new gas cell for tritium use
- Progress in commissioning the detector system
- Outline of future experimental goals

## Abstract

Following the successful observation of single conversion electrons from $^{83m}$Kr using Cyclotron Radiation Emission Spectroscopy (CRES), Project 8 is now advancing its focus toward a tritium beta decay spectrum. A tritium spectrum will be an important next step toward a direct measurement of the neutrino mass for Project 8. Here we discuss recent progress on the development and commissioning of a new gas cell for use with tritium, and outline the primary goals of the experiment for the near future.
