We present an apparatus for detection of cyclotron radiation that allows afrequency-based beta energy determination in the 5 keV to 5 MeV range,characteristic of nuclear beta decays. The cyclotron frequency of the radiatingbeta particles in a magnetic field is used to determine the beta energyprecisely. Our work establishes the foundation to apply the cyclotron radiationemission spectroscopy (CRES) technique, developed by the Project 8collaboration, far beyond the 18-keV tritium endpoint region. We report initialmeasurements of beta^-s from 6He and beta^+s from 19Ne decays to demonstratethe broadband response of our detection system and assess potential systematicuncertainties for beta spectroscopy over the full (MeV) energy range. This workis an important benchmark for the practical application of the CRES techniqueto a variety of nuclei, in particular, opening its reach to searches forevidence of new physics beyond the TeV scale via precision beta-decaymeasurements.

First observation of cyclotron radiation from MeV-scale ${\rm e}^{pm}$ following nuclear beta decay
