WG2: Introduction and news

• Sajan Easo (Science and Technology Facilities Council STFC (GB))

Fast infra-red photon detectors for particle identification

• Simone Bini

These were developed for astro-particle experiments. The details of these developments and the possibility to use them for HEP experiments will be discussed. One interesting aspect is the potential to have reduced chromatic error in the Cherenkov angle measurement, compared to that from detectors optimized for the UV part of the spectrum.

Radiator gases in future Cherenkov detectors: Development, circulation and monitoring

• Gregory Hallewell (Centre National de la Recherche Scientifique (FR))

Aspects related to the thermodynamic circulation of the gases will be presented. R&D needed for the development of radiator gases will be discussed.
