| First Observation of Cyclotron Radiation from MeV-Scale $e^{\pm}$ following Nuclear $\beta$ Decay, W. Byron, H. Harrington, R. J. Taylor, W. DeGraw, N. Buzinsky, B. Dodson, M. Fertl, A. García, G. Garvey, B. Graner, M. Guigue, L. Hayen, X. Huyan, K. S. Khaw, K. Knutsen, D. McClain*, D. Melconian*, P. Müller, E. Novitski, N. S. Oblath, R. G. H. Robertson, G. Rybka, G. Savard, E. Smith, D. D. Stancil, M. Sternberg, D. W. Storm, H. E. Swanson, J. R. Tedeschi, B. A. VanDevender, F. E. Wietfeldt, A. R. Young, characteristic of nuclear β decays. The cyclotron frequency of the radiating β particles in a magnetic field is used to determine the β energy precisely. Our work establishes the foundation to apply the cyclotron radiation emission spectroscopy (CRES) tec Zhu, X.} abstract = {We present an apparatus for detection of cyclotron radiation yielding a frequency-based β± kinetic energy determination in the 5 keV to 2.1 MeV range, β+’s from 19Ne decays to demonstrate the broadband response of our detection system and opening its reach to searches for new physics beyond the TeV scale via precision β-decay measurements. assess potential systematic uncertainties for β spectroscopy over the full (MeV) energy range. To our knowledge, this is the first direct observation of cyclotron radiation from individual highly relativistic β’s in a waveguide. This work establishes the application of CRES to a variety of nuclei, Phys. Rev. Lett. 131, 082502 (2023)
