  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 20GeV 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. The set-up installed in FACET consists in four targets (three gratings and a blank) on a carrousel on one side and eleven pyroelectric detectors on the opposite side, the beam passing between. At the moment, the measurement is averaged over a hundred pulses or more. We have studied the stability of the measurement from pulse to pulse and the resolution of the measure depending on the number of grating used.
