“…A second field, generated between the gate and the positively-biased anode, extracts them into the gas phase and provides the electrons sufficient energy to excite and ionize the gas atoms. This generates a secondary scintillation signal (S2) which is proportional to the number of extracted electrons [27]. The position of the initial interaction, as well as the scatter multiplicity, can be reconstructed in 3-dimensions from the position and number of S2 signals observed by the top photosensors and the S1-S2 time difference.…”

The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2 t liquid xenon inventory, 2.0 t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This article describes the XENON1T instrument and its subsystems as well as strategies to achieve an unprecedented low background level. First results on the detector response and the performance of the subsystems are also presented.

“…Typically, two arrays of photosensors, on top and bottom of the detector, are employed to detect the prompt light signal. Ionised electrons are drifted upwards to the liquid-gas surface and amplified via proportional scintillation in the gas phase [340] which is also measured by the photosensor arrays. Therefore, double phase detectors are operated as a Time Projection Chamber (TPC, see figure 13 right).…”

Abstract.In the past decades, several detector technologies have been developed with the quest to directly detect dark matter interactions and to test one of the most important unsolved questions in modern physics. The sensitivity of these experiments has improved with a tremendous speed due to a constant development of the detectors and analysis methods, proving uniquely suited devices to solve the dark matter puzzle, as all other discovery strategies can only indirectly infer its existence. Despite the overwhelming evidence for dark matter from cosmological indications at small and large scales, a clear evidence for a particle explaining these observations remains absent. This review summarises the status of direct dark matter searches, focussing on the detector technologies used to directly detect a dark matter particle producing recoil energies in the keV energy scale. The phenomenological signal expectations, main background sources, statistical treatment of data and calibration strategies are discussed.arXiv:1509.08767v2 [physics.ins-det]

“…Later, proportional scintillation was observed in the non-uniform field in the vicinity of very thin wires [368,358,369,370]. For example, with a wire of 4 µm diameter a light yield of ∼10-100 photons per primary electron was obtained [369].…”

We review the current status of liquid noble gas radiation detectors with energy threshold in the keV range, which are of interest for direct dark matter searches, measurement of coherent neutrino scattering and other low energy particle physics experiments. Emphasis is given to the operation principles and the most important instrumentation aspects of these detectors, principally of those operated in the double-phase mode. Recent technological advances and relevant developments in photon detection and charge readout are discussed in the context of their applicability to those experiments.
