SIMPLE Dark Matter Experiment

Welcome to the SIMPLE homepage


The SIMPLE (Superheated Instrument for Massive ParticLe Experiments) dark matter search project is located in a 61 m3 cavern at the 500 level of the Laboratoire Souterrain à Bas Bruit (LSBB) near Apt in southern France.
The project detector, until recently,  is based on superheated droplet detectors (SDDs), a suspension of 1%–2% superheated liquid C2ClF5 droplets (~ 30 mm radius) in a viscoelastic 900 ml gel matrix which undergo transitions to the gas phase upon energy deposition by incident radiation.
