| Abstract | The angular distribution of coherent Smith-Purcell radiation, produced from the interaction of a 4.75 MeV electron beam with a metallic grating, has been used to infer the longitudinal profile of the electron bunches of the Frascati Microtron. The emitted radiation is in the far infrared and the various wavelengths were collected by varying the angle of observation over the range of 40 o to 140 o . The radiated power levels were of the order of 100 mW and agree well with the description of the process in terms of surface currents induced on the grating profile. It is concluded that the bunch has an approximately triangular profile, with 80% of the particles contained within 16ps. The technique offers interesting possibilities as a non-intercepting diagnostic tool for the determination of bunch shapes, with minimal disruption to the beam. |
