Query: PICOSEC: Charged particle timing at sub-25 picosecond precision with a
  Micromegas based detector   The prospect of pileup induced backgrounds at the High Luminosity LHC
(HL-LHC) has stimulated intense interest in developing technologies for charged
particle detection with accurate timing at high rates. The required accuracy
follows directly from the nominal interaction distribution within a bunch
crossing ($\sigma_z\sim5$ cm, $\sigma_t\sim170$ ps). A time resolution of the
order of 20-30 ps would lead to significant reduction of these backgrounds.
With this goal, we present a new detection concept called PICOSEC, which is
based on a "two-stage" Micromegas detector coupled to a Cherenkov radiator and
equipped with a photocathode. First results obtained with this new detector
yield a time resolution of 24 ps for 150 GeV muons, and 76 ps for single
photoelectrons.
