Modeling a new superconducting beta spectrometer for a CVC test in ^14O beta decay
Abstract
Precision beta-decay experiments can constrain possible extensions to the Standard Model of the weak interaction. Measurements of the shape of the beta spectrum in ^14O are particularly sensitive tests of the conserved vector current (CVC) hypothesis. We are planning to measure the shape factor of the 0^+ arrow 1^+ transition in ^14O with a newly-constructed iron-free superconducting beta spectrometer. In order to reduce and correct for energy-dependent instrumental distortions of the spectrum, we are carrying out simulations using EGSnrc (a Monte Carlo code system for electron-photon transport). In particular, we are investigating energy-dependent spectral distortions caused by scattering within the spectrometer and by backscattering out of the detector. We will present an overview of the planned experiment and results of the simulations.
