Description
Picosec is a novel micropattern gaseous detector (MPGD) proposed by the RD51
collaboration to overcome the limitations of classical MPGDs in terms of timing
performance. The concept is based on detecting Cherenkov light emitted by an
impinging particle in a proper radiator. A photocathode converts such light into
electrons, and a double amplification stage MicroMegas detector detects them. The
Picosec RD51 collaboration has already demonstrated the standalone functionality
of this technology, reaching an excellent time resolution of 24 ps.
This technology opens the timing sector on tens of picoseconds to gaseous
detectors, making them competitive with other fast-timing technologies but with the
traits of MPGD. We aim to build and develop a robust and reliable standard for this
detector technology capable of operating in next-generation facilities. This goal can
be reached by searching for radiation-hard photocathodes, new eco-friendly gas
mixtures and robust Cherenkov radiators.
In particular, the Picosec technology is currently proposed for the Muon Collider
detector as a muon timing station where it can contribute to the enhancement of the
quality of the muon tracks.
