CHEREN2, the Cherenkov counting efficiency by an anisotropy detection model

Abstract The commercially available liquid-scintillation spectrometers are also feasible for the detection of the Cherenkov light emitted by β-rays in transparent liquids, when the maximum-point energy of the Fermi distribution is greater than the Cherenkov threshold energy. We present a second version of the program CHEREN, which applies Poisson statistics to compute the two photomultipliers counting efficiency. We redefine previous version free parameters, including two new different coefficients in... Title of program: CHEREN2 Catalogue Id: ADIE_v2_0 [ADWJ] Nature of problem Although a liquid-scintillation spectrometer can be applied to count Cherenkov light photons free of noise interference, the non-isotropic character of the Cherenkov light emission reduces the counting efficiency of the two-phototube system working in coincidence, and makes the Cherenkov light measurements comparatively much less efficient than with scintillators. However, the application of standardization techniques based on Cherenkov counting is recommended when the radioactive sample cannot ...
