Description
At present, some of the most sensitive dark matter and neutrino-less double beta decay search experiments use liquid xenon as the target/detection medium. At the expense of larger volumes and reduced self shielding, operation in the more dilute gas phase at room temperature and high pressure offers some trade-off advantages. Room temperature gases that enhance the performance (e.g. diffusion) can be easily added to the xenon. Other advantages include the proven better energy resolution and the demonstrated ability to do track imaging in the MeV region.
At LBNL over the past six years we have pursued a range of measurements and simulations within the framework of a high-pressure xenon instrumentation R&D program. In this talk I will present some of the highlight results from this program.
