High-purity germanium (HPGe) is a vibration-sensitive, high-resolution detector. It has been found that microphonic noise induced by vibration and electromagnetic interference from EMC causes energy resolution degradation in HPGe detectors. In this paper, to enhance the of pulse tube-cooled high purity detector, passive isolation system for portable tube cooler (PTC) was employed investigated. ...

This article reports the measurement of ionization quenching factor in germanium for nuclear recoil energies between 0.4 and 6.3 keV$_{nr}$. Precise knowledge this energy range is relevant coherent elastic neutrino-nucleus scattering low mass dark matter searches with germanium-based detectors. Nuclear recoils were produced a thin high-purity target very threshold via irradiation monoenergetic ...

Events from alpha interactions on the surfaces of germanium detectors are a major contribution to background in germanium-based searches for neutrinoless double-beta decay. Surface events subject charge trapping, affecting their pulse shape and reconstructed energy. A study passivated end-plate segmented true-coaxial n-type high-purity detector is presented. Charge trapping analysed detail an e...

objective(s): gallium‐68 (ga‐68) is an ideal research and hospital‐based pet radioisotope. currently, the main form of ga‐68 radiopharmaceutical that is being synthesised in‐house is ga‐68 conjugated with dota based derivatives. the development of automated synthesis systems has increased the reliability, reproducibility and safety of radiopharmaceutical productions. here we report on our three...

The first result of the neutrino magnetic moment measurement at the Kalininskaya Nuclear Power Plant (KNPP) with the GEMMA spectrometer is presented. An antineutrino-electron scattering is investigated. A high-purity germanium detector of 1.5 kg placed 13.9 m away from the 3 GW reactor core is used in the spectrometer. The antineutrino flux is 2.73×1013 ν̄e/cm/s. The differential method is used ...

Portable, high-resolution gamma spectroscopy has long been a vital technique in routine safeguards accountancy. The high resolution enables the spectrum analysis to accurately determine the isotopic content of the sample. All currently deployed systems for this application are based on liquid-nitrogen cooled, high-purity germanium (HPGe) detectors, with the spectrum analysis performed on portab...
