Abstract Novel NaIL detector (5 × 6 inch) was investigated for its neutron detection in wide energy range. It has been found that the together with known ability to detect γ-radiation it also allows distinguish signals three quasi-independent ways. is sensitive fluxes on a level down 10 -3 cm -2 s -1 . In this work intrinsic α-background and sensitivity were obtained. Experimental data compared...

The scintillation efficiency of electron recoils in liquid xenon (LXe) is not well measured at low energies. The Compton coincidence technique (CCT) is set up using a NaI(Tl) detector and HPGe detector to measure the energy dependence of the light yield in the NaI(Tl) detector from which we can extract the scintillation effieciency. This technique allows for the detection of low energy electron...

Measurements of the shapes of scintillation pulses produced by nuclear recoils, alpha particles and photons in NaI(Tl) crystals at visible energies of 10-100 keV have been performed in order to investigate possible sources of background in NaI(Tl) dark matter experiments and, in particular, the possible origin of the anomalous fast time constant events observed in the UK Dark Matter Collaborati...

The term ‘thermal flux’ implies a Maxwellian distribution of velocity and energy corresponding to the most probable velocity of 2200 m s−1 at 293.4 K. In order to measure the thermal neutron flux density, the foil activation method was used. Thermal neutron flux determination in paraffin phantom by counting the emitted rays of indium foils with two different detectors (Geiger– Muller counter an...

Scintillators play an important role in radiation detection and imaging. Thallium-doped cesium iodide (CsI:Tl) sodium (NaI:Tl) are two of the major scintillators that have been used for many applications decades. In this paper, we will present improved scintillation performance Bridgman method-grown CsI(Tl) NaI(Tl) crystals developed by Xtallized Intelligence, Inc. (XI, Inc.), compare with comm...
