The Argon Dark Matter Experiment (ArDM)

TL;DR

The ArDM experiment is a large liquid argon detector designed to identify dark matter particles through their interactions with argon nuclei, using light and charge signals to distinguish potential events.

Contribution

This paper introduces the design and main components of the ArDM detector, a novel large-scale liquid argon TPC for dark matter detection.

Abstract

The ArDM experiment, a 1 ton liquid argon TPC/Calorimeter, is designed for the detection of dark matter particles which can scatter off the spinless argon nuclei. These events producing a recoiling nucleus will be discerned by their light to charge ratio, as well as the time structure of the scintillation light. The experiment is presently under construction and will be commissioned on surface at CERN. Here we describe the detector concept and give a short review on the main detector components.
