High-precision measurements of angular correlations in neutron beta decay address a number of questions which are at the forefront of particle physics. For a new generation of beta decay experiments, like the PERC (Proton Electron Decay Channel) [1, 2] experiment currently under construction in Munich, frequency-based beta spectroscopy methods using the cyclotron radiation emitted by electrons in a homogeneous magnetic field have been emerging as new approaches for high-precision beta spectroscopy. The CREScent experiment is a proof-of- principle experiment aiming to combine the CRES (Cyclotron Radiation Emission Spectroscopy)-technique [3] with the signal amplification qualities of a RF cavity, naturally compensating for the extremely weak signal power of the expected cyclotron radiation pulses.
