ArDM(Argon Dark Matter)是一个侦测暗物质的实验，利用液态氩侦测大质量弱交互作用粒子（Weakly Interacting Massive Particles，简称：WIMP）的实验，WIMP是暗物质的可能组成之一，在2006年在CERN实行，公用掉了一顿的液态氩，原理是当它与氩原子，氩原子会离子化，而产生可以被仪器增测到的电子。有时WIMP会撞上氩原子核，而把它的能量传给原子核，一般应该是介于1keV到100keV之间。虽然不知道弱交互作用质量粒子与氩原子撞击的机率是多少，但根据超对称理论应该每天会有100到0.01个撞击事件发生。这个实验最困难的地方就是，液态氩里可能有氩-39，他是一种半衰期269年的同位素，可能会经由β衰变释放出能量565 keV的电子，因此仪器必须设计分变的出才行。

The ArDM (Argon Dark Matter) Experiment is a particle physics experiment based on a liquid argon detector, aiming at measuring signals from WIMPs (Weakly Interacting Massive Particles), which probably constitute the Dark Matter in the universe. Elastic scattering of WIMPs from argon nuclei is measurable by observing free electrons from ionization and photons from scintillation, which are produced by the recoiling nucleus interacting with neighbouring atoms. The ionization and scintillation signals can be measured with dedicated readout techniques, which constitute a fundamental part of the detector.
