18. Dual-Polarity Ion Drift Chamber: Experimental results with Xe-SF6 mixtures

Afonso Marques (LIP)

A new experimental system was recently developed by our group to measure the mobility of both positive and negative ions: the Dual-Polarity Ion Drift Chamber (DP-IDC) [1]. This new system is intended to foster the understanding of transport properties of ions in gases, as these are especially relevant for the performance of gaseous detectors, namely in large volume ones, in particular for the...

14. GPU-based optical simulation of the DARWIN detector

Igor Ostrovskiy (University of Alabama)

Understanding propagation and detection of scintillation light is critical for maximizing the discovery potential of next-generation liquid xenon detectors that use dual-phase time projection chamber technology. This talk describes a detailed optical simulation of the DARWIN detector implemented using Chroma, a GPU-based photon tracking framework. Advantages of the framework are discussed,...

37. Rugged and radiopure amplification structures for large-area xenon chambers read out through electroluminescence

Sara Leardini

Large scintillation gaps are desirable for electroluminescence chambers with ultimate energy resolution and single-electron counting characteristics, whereas large-area amplification structures are needed for next-generation ton-scale experiments. We present systematic studies of a custom designed structure (Field-Assisted Transparent Gas Electroluminescence Multiplier, or FAT-GEM), consisting...

25. SiPM readout of Xenoscope, a full-scale DARWIN vertical demonstrator

Ricardo Peres (University of Zurich)

The DARWIN project aims to build and operate a next-generation observatory for dark matter and neutrino physics, featuring a time projection chamber (TPC) with a proposed active target of 40 t of liquid xenon (LXe) [1,2]. As an R&D facility to test fundamental components of the future detector, Xenoscope, a full-scale vertical demonstrator with 350 kg of LXe and up to 2.6 m electron drift...

23. The development of hermetic quartz chamber for future low background liquid xenon detectors

Dr Masatoshi Kobayashi (Institute for Space-Earth Environmental Research, Nagoya University)

Liquid xenon detectors have been one of the leading technologies in low radioactive background experiments. For these low background detectors, Rn and its daughters are current major background to be improved.
Toward the future experiment, the idea of hermetic Time Projection Chamber (TPC) is to build fully-isolated inner detector volume with VUV-transparent quartz and shield Rn atoms...

32. Xenoscope — a full-scale vertical demonstrator for the DARWIN observatory

Laura Baudis (University of Zurich)

The DARWIN observatory is a proposed next-generation experiment to search for particle dark matter and other rare interactions. It will operate a 50 t liquid xenon detector, with 40 t in the time projection chamber (TPC). To inform the final detector design and technical choices, a series of technological questions must first be addressed. I will describe a full-scale demonstrator in the...
