Query: Resolution of Longitudinal Profile Measures using Coherent Smith-Purcell
  Radiation with the Number of Gratings and the Number of Pulses Used   The E-203 collaboration is testing a device on FACET at SLAC to measure the
longitudinal profile of electron bunches using Smith-Purcell radiation. At
FACET the electron bunches have an energy of 20~GeV and a duration of a few
hundred femtoseconds. Smith-Purcell radiation is emitted when a charged
particle passes close to the surface of a metallic grating. We have studied the
stability of the measurement from pulse to pulse and the resolution of the
measure depending on the number of gratings used.
