This paper focuses on constraining the erosion rate in the area of the Allchar Sb-As-Tl-Au deposit (Macedonia). It contains the largest known reserves of lorandite (TlAsS 2), which is essential for the LORanditeEXperiment (LOREX), aimed at determining the long-term solar neutrino flux. Because the erosion history of the Allchar area is crucial for the… (More)
Digital ratemeter that operates according to a self-adjusting algorithm, which at low rates automatically switches from a preset count to the preset time method, is proposed. It combines the good properties of both methods concerning the accuracy of the measured average counting rate and the response time to sudden changes of rate.
