“…Such a validated performance allows the community to rely on simulations for the calculation of the response function of the present 𝛽 detectors. This was not possible in the 1980s, when limitations in the simulations caused Tengblad et al to use a parametric response function experimentally determined with mono-energetic electrons for the deconvolution of experimental data [64].…”

The shape of the electron spectrum emitted in β decay carries a wealth of information about nuclear structure and fundamental physics. In spite of that, few dedicated measurements have been made of β-spectrum shapes. In this work we present a newly developed detector for β electrons based on a telescope concept. A thick plastic scintillator is employed in coincidence with a thin silicon detector. The first measurements employing this detector have been carried out with mono-energetic electrons from the high-energy resolution electron-beam spectrometer at Bordeaux. Here we report on the good reproduction of the experimental spectra of mono-energetic electrons using Monte Carlo simulations. This is a crucial step for future experiments, where a detailed Monte Carlo characterization of the detector is needed to determine the shape of the β-electron spectra by deconvolution of the measured spectra with the response function of the detector. A chamber to contain two telescope assemblies has been designed for future β-decay experiments at the Ion Guide Isotope Separator On-Line facility in Jyväskylä, aimed at improving our understanding of reactor antineutrino spectra.

“…The detection of β particles has been explored for many years using a variety of detector systems having a wide range of efficiency and resolution, viz., magnetic spectrometer [1], plastic scintillators [2], silicon [3] and germanium solid state detectors [4,5]. The magnetic spectrometer provides very high energy resolution but is limited in its efficiency and it is not considered suitable for the measurement involving short lived β decaying state.…”

The end point energies of nuclear β decays have been measured with a segmented planar Ge LEPS detector using both singles and coincidence techniques. The β − γ coincidence has been performed with a segmented planar Ge LEPS and a single 10% HPGe detector. The γ ray and β particle responses of the Segmented planer Ge LEPS detector were studied using monte carlo simulation code GEANT3. The experimentally obtained β spectrum was in reasonably good agreement with the simulation results. The experimental end point energies are determined with substantial accuracy for some of the known β decays in 106 Rh, 210 Bi and 90 Y. The end point energies corresponding to three weak branches in 106 Rh → 106 Pd decay has been measured for the first time.
