Geochemical and physical research within the LOREX-project II

The project LOREX is the acronym of LORandite EXperiment, which addresses the long-time detection of solar neutrinos with the 205 Tl-bearing mineral lorandite (TlAsS2) at the mine of Allchar, Macedonia, via the neutrino- capture reaction 205 Tl + e 205 Pb + e-. LOREX is the only long-time geochemical solar neutrino experiment still actively pursued. If accomplished, it will contribute to the understanding of the standard solar model by measuring the solar pp-neutrino flux above an unprecedented low threshold for the neutrino energy of Ee = 52 keV. Moreover, LOREX would be a unique experiment while providing the mean luminosity of the sun over the last 4 million years. The results of LOREX provide supplementary information to other solar neutrino experiments such as GALLEX or SAGE.

The results of LOREX provide supplementary information to other solar neutrino experiments such as GALLEX or SAGE. During LOREX II, it was possible to extract under very difficult circumstances 1000 g of purest lorandite from the mine of Crven Dol in Allchar, which can be used for forthcoming investigations.
