“…The value W s = 72 ± 6 eV is extracted in [25], for gas pressures in the 1-3 bar range and for drift fields in the 0.15-0.6 kV/cm•bar range, with no significant variations with pressure and with field. Finally, the authors of [26] measure W s = 26 +7 −6 eV at 40 bar pressure and no electric field. The difference between these results is presently not fully understood, as it can be attributed only partially to the different gas density and drift field conditions.…”

High-pressure xenon gas is an attractive detection medium for a variety of applications in fundamental and applied physics. In this paper we study the ionization and scintillation detection properties of xenon gas at 10 bar pressure. For this purpose, we use a source of alpha particles in the NEXT-DEMO time projection chamber, the large scale prototype of the NEXT-100 neutrinoless double beta decay experiment, in three different drift electric field configurations. We measure the ionization electron drift velocity and longitudinal diffusion, and compare our results to expectations based on available electron scattering cross sections on pure xenon. In addition, two types of measurements addressing the connection between the ionization and scintillation yields are performed. On the one hand we observe, for the first time in xenon gas, large event-by-event correlated fluctuations between the ionization and scintillation signals, similar to that already observed in liquid xenon. On the other hand, we study the field dependence of the average scintillation and ionization yields. Both types of measurements may shed light on the mechanism of electron-ion recombination in xenon gas for highly-ionizing particles. Finally, by comparing the response of alpha particles and electrons in NEXT-DEMO, we find no evidence for quenching of the primary scintillation light produced by alpha particles in the xenon gas.-2 -

“…A special version of the 4-Helium detectors has been specifically developed including a Li converter to detect also slow neutrons that are discriminated from the fast component by a novel technique illustrated in Fig.3. Xenon is an attractive material for gamma ray detection, mainly because of its high atomic number (Z = 54) and large cross-section for photo-electric absorption (photo-electric crosssection dominates up to around 300 keV) [6]. Looking to the scintillation light, the xenon detector is not susceptible to vibrational disturbance and micro-phonic effects typically associated to previously developed detectors using Ionization Chamber technology.…”

The project MODES_SNM, Modular DEtection System for Special Nuclear Material, is presented in this paper. Its main objective is the development of a mobile and modular detection system specially designed for SNM, i.e. highly enriched Uranium and weapon grade Plutonium, but with the capability of detecting and identifying radioactive sources. The MODES_SNM prototype is defined as a Portable Radiation Scanner following the IAEA classification that can be used in primary or secondary lines of control depending on the operational need as fixed or mobile system. High pressure noble gas scintillation detectors for neutrons and gamma rays are employed in the detection system.

“…Enhancement is expected in terms of detection efficiency as well as portability and mobility, with a system capable to detect and identify the sources of interest. The consortium is developing a detector suite based on the ARKTIS technology, with solutions for thermal neutron detection based on a 4 He filled high pressure tube Li coated and a detector with spectrometric capability replacing 4 He with Xenon [11]. The ARKTIS technology relies on three features of He: Fig.…”
