Indium Solar Neutrino Experiments

The possibility of detecting low-energy solar neutrinos through inverse β-decay in 115In was first discussed by R. S. Raghavan [1] in 1976. An indium experiment has unique features in that it is possible to measure the energy spectrum of solar neutrinos above 125 keV in real time. Although a variety of ideas concerning indium detectors have been discussed from time to time, and sophisticated ideas have been presented on various occasions, no practical designs for indium detectors have yet been demonstrated. We focus on discussions of problems that stand in the way of realizing a viable experiment in section 3. A survey of past and present development projects of the detector is given in section 4. A practical detector design and detailed background considerations for a dedicated detector for 7Be-pep neutrino detection are given in section 5.

    InCl3–4H2O(Indium tri-chloride tetra hydrate) is also resolved in water [see [16]]. The maximum indium loading of 35% was actually obtained. This indium contained water is very transparent and the density is 1.85g/cm3. The index of reflection is about 1.7. By adding CeCl3 to the indium loaded water as a wavelength shifter, 360 nm light emission through an 260 nm excitation by a xenon lump was obtained. The indium loaded heavy water can be used as a Cherenkov detector with Ce activator. But this cannot be used as a scintillator since the liquid does not have an energy transfer property.Google Scholar
