Cyclotron Radiation Emission Spectroscopy (CRES) is a high-precision and low-background approach to beta spectroscopy, in which the energy of an e^± in an external magnetic field is measured via the frequency of its emitted cyclotron radiation. The He6-CRES experiment is aimed at applying CRES to the beta decay spectra of ¹⁹Ne and ⁶He, with the goal of discovering a potential non-zero value for the Fierz interference term, which would be indicative of new physics. In this talk, I will present the current status of the He6-CRES apparatus, comparing data to simulations as a benchmark of our experimental knowledge. The outlook for the future sensitivity of the experiment will also be discussed.
