Description

The detector consists of a large spherical gas volume with a central electrode forming a radial electric field. A small spherical sensor located at the center is acting as a proportional amplification structure. This new concept has been proven to operate in a simple and robust way and allows reading large volumes with a single read-out channel. I will present results on WIMP search taken in the LSM underground laboratory in Neon gas and sub-keV energy threshold using a 60cm high pressure detector. The versatility of the target (Ne, He, H) opens the way to search for ultra light dark matter WIMPs down to 100 MeV. Such a device would open the way to detect the neutrino-nucleus interaction or supernova detection. I will mention prospects for ultra-low background high pressure detector and the optimization of such detector for a competitive double beta decay experiment using Xe-136 high-pressure target.
