Ionization and scintillation response of high-pressure xenon gas to alpha particles

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 -

“…The feasibility of the LAr-TPC technology has been largely demonstrated in the last decades through the operation of ICARUS prototypes/detectors of increasing mass (3 tons, 14 tons, 300 tons) [3]. Presently there is also an active program in the US to develop LAr-TPCs with the final goal of constructing a massive detector (20 ktons of mass) for a long-baseline (1300 km) neutrino oscillation experiment.…”

Abstract. Liquid Argon Time Projection Chamber technology provides unique features in event imaging and calorimetric resolution. These characteristics, combined with a good rejection power and a (virtually) unlimited active mass, make this detector one of the best candidate for the next generation of long-baseline neutrino oscillation experiments aimed at precision measurements of the MNPS matrix elements. Up to now the largest LAr-TPC operated is the first semi-module of the ICARUS T600 detector (300 tons of LAr). The scalability of this technology to massive detectors (≥ 5 ktons) is still to be proven. The ArgoNeuT detector, a small LAr-TPC (0.24 ton of active mass) exposed to the NuMI beam at FNAL currently producing the first low-energy neutrino events in a LAr-TPC, is the first step of a staged US program to realize and operate a massive LAr-TPC detector. The proposed MicroBooNE experiment, a LAr-TPC of 100 tons of active mass, to be exposed to the Booster Neutrino Beam and the NuMI beam at FNAL, is the next crucial step of this program. Design details and experimental goals of both experiments are reported in this paper.

“…The largest of these devices had a mass of 3 tons of LAr [12,13] and has been continuously operated for more than four years, collecting a large sample of cosmicray and gamma-source events. Furthermore, a smaller device with 50 l of LAr [14] was exposed to the CERN neutrino beam, demonstrating the high recognition capability of the technique for neutrino interaction events.…”

We review detector technologies which are currently considered for ultimate nucleon decay searches, new generation astrophysical neutrinos studies, and for future long-baseline neutrino experiments at new high-intensity neutrino beam facilities. We focus our discussion on Phase-II experiments with a timescale of 10 ≃ 20 years. We point out that there are very few detector technologies which are general purpose and versatile enough in order to potentially address non-accelerator based physics and a large variety of future neutrino beam types ranging from superbeams, betabeams and neutrino factories from subGeV to 10's GeV energies.
