Scintillation characteristics of a NaI(Tl) crystal at low-temperature with silicon photomultiplier
نویسندگان
چکیده
Scintillation characteristics of a thallium doped sodium iodide (NaI(Tl)) crystal with dimension 0.6 x 2 cm3 are studied by attaching silicon photomultiplier (SiPM) direct to the over temperature range from 93 300 K. The scintillation light output and decay time measured irradiating 59.54 keV gamma-rays 241Am source. We observed approximately 20% increase in yield at 230K compared that room temperature. At this condition, NaI(Tl) coupled SiPM can be good candidate for future dark matter search detector.

Detection of Liquid Xenon Scintillation Light with a Silicon Photomultiplier
We have studied the feasibility of a silicon photomultiplier (SiPM) to detect liquid xenon (LXe) scintillation light. The SiPM was operated inside a small volume of pure LXe, at -95C, irradiated with an internal Am α source. The gain of the SiPM at this temperature was estimated to be 1.8 × 10 with bias voltage at 52 V. Based on the geometry of the setup, the quantum efficiency of the SiPM was ...
متن کاملThe Digital Silicon Photomultiplier
The Silicon Photomultipliers (SiPMs) are the new step in the development of the mod‐ ern detection structures in the area of low photon flux detection with a unique capa‐ bility of detection up to the single photons. The Silicon Photomultiplier intrinsically represents a digital signal source on the elementary cell level. The materials and tech‐ nology of SiPMs are consistent with the modern el...

The gamma-ray excited, temperature dependent scintillation characteristics of CsI(Tl) are reported over the temperature range of -100 to +50°C. The modified Bollinger-Thomas and shaped square wave methods were used to measure the rise and decay times . Emission spectra were measured using a monochromator and corrected for monochromator and photocathode spectral efficiencies . The shaped square ...
متن کاملFormation of single-crystal silicon nanoparticles at very low gas temperature in a rf silane-based discharge
Introduction The synthesis of single-crystal silicon nanocrystals we present is performed in the gas phase of a radio frequency (rf) discharge. The plasma is produced in a discharge box, enclosed in a vacuum vessel, containing an Ar/SiH4 mixture (92:8). The typical pressure is 0.12 mbar while typical rf injected power is 10 W. Gas temperature can be decreased to -40 oC. Dust particle formation ...
متن کاملSymmetry-broken crystal structure of elemental boron at low temperature
The crystal structure of boron is unique among chemical elements, highly complex, and imperfectly known. Experimentalists report that the -rhombohedral black form is stable over all temperatures from absolute zero to melting. However, early calculations found its energy to be greater than the energy of the -rhombohedral red form, implying that the phase cannot be stable at low temperatures. Fur...
