Query: PICOSEC: Charged particle Timing to 24 picosecond Precision with
  MicroPattern Gas Detectors   The prospect of pileup induced backgrounds at the High Luminosity LHC
(HL-LHC) has stimulated intense interest in technology for charged particle
timing at high rates. In contrast to the role of timing for particle
identification, which has driven incremental improvements in timing, the LHC
timing challenge dictates a specific level of timing performance- roughly 20-30
picoseconds. Since the elapsed time for an LHC bunch crossing (with standard
design book parameters) has an rms spread of 170 picoseconds, the $\sim50-100$
picosecond resolution now commonly achieved in TOF systems would be
insufficient to resolve multiple "in-time" pileup. Here we present a MicroMegas
based structure which achieves the required time precision (ie 24 picoseconds
for 150 GeV $\mu$'s) and could potentially offer an inexpensive solution
covering large areas with $\sim 1$ cm$^2$ pixel size. We present here a
proof-of-principle which motivates further work in our group toward realizing a
practical design capable of long-term survival in a high rate experiment.
