Scintillating crystal detector may offer some potential advantages in the low-energy, low-background experiments. A 500 kg CsI(Tl) detector to be placed near the core of Kuo-sheng Nuclear Power ...Station in Taiwan is being constructed for the studies of electron–neutrino scatterings and other keV–MeV range neutrino interactions. The motivations of this detector approach, the physics to be addressed, the basic experimental design, and the characteristic performance of prototype modules are described. The expected background channels and their experimental handles are discussed.
The geometrical parameters which affect the suppression factor for a HpGe-NaI(Tl) Compton suppression spectrometer are studied by Monte Carlo simulation. The simulation parameters are designed for ...comparison of the experimental results of the specified Compton suppression spectrometer with a HpGe detector as the central detector. The simulated results are in coincidence with the experimental results. The optimal position of the HpGe detector within the shielding of the NaI(Tl) detector in two kinds of asymmetry Compton suppression spectrometer, which we named L(T)-shape and L(C)-shape is studied. The optimized suppression position is consistent with the previous simulated results, that the front face of the central detector is about at

length of the shielding along the hole dimension. Further simulation indicates that the suppression factor is quickly saturated by increasing the shielding thickness along the dimension perpendicular to the hole for the central detector.
