“…Water is efficiently removed by a filter containing molecular sieves. Using this method, the total impurity concentration was reduced in 5 hours from 250 ppb to 40 ppb in the total 100 liters LXe volume of the MEG prototype (174).…”

This article reviews the progress made over the last 20 years in the development and applications of liquid xenon detectors in particle physics, astrophysics and medical imaging experiments. We begin with a summary of the fundamental properties of liquid xenon as radiation detection medium, in light of the most current theoretical and experimental information. After a brief introduction of the different type of liquid xenon detectors, we continue with a review of past, current and future experiments using liquid xenon to search for rare processes and to image radiation in space and in medicine. We will introduce each application with a brief survey of the underlying scientific motivation and experimental requirements, before reviewing the basic characteristics and expected performance of each experiment. Within this decade it appears likely that large volume liquid xenon detectors operated in different modes will contribute to answering some of the most fundamental questions in particle physics, astrophysics and cosmology, fulfilling the most demanding detection challenges. From experiments like MEG, currently the largest liquid xenon scintillation detector in operation, dedicated to the rare "µ → eγ" decay, to the future XMASS which also exploits only liquid xenon scintillation to address an ambitious program of rare event searches, to the class of time projection chambers like XENON and EXO which exploit both scintillation and ionization of liquid xenon for dark matter and neutrinoless double beta decay, respectively, we anticipate unrivaled performance and important contributions to physics in the next few years.PACS numbers: 95.35.+d, 29.40.Mc,95.55.Vj

“…To identify and separate pileup γ rays efficiently, fast waveform digitizers are used for all the photomultiplier tube outputs (33). Possible impurities (mostly water) that absorb scintillation light are eliminated by circulating liquid xenon through a purification system (34,35). Stability monitoring and precise calibration of the liquid xenon detector are key to the success of the experiment.…”

“…can absorb UV light and act as inefficient wave-length shifter or as quenchers degrading light col-lection [64]. When scintillation light is absorbed by some impurities the consequent overlap of the absorption and emission light could be the cause of a position dependence of the detector response already observed in the past [65,66]. This phenomenon also affects, to varying degrees, the performances of dual phase detectors discussed in this paper (see Sect.…”
