Description
We have developed a periodic Cherenkov radiator to obtain narrow band Cherenkov radiation. Since the radiation spectrum of Cherenkov diffraction radiation from the radiator contains strong higher order harmonics, the bunch form factor of the electron beam is expected to be deduced precisely, so that the very short bunch less than 10 fs (such as the laser wakefield accelerated beam) is able to be measured. We have done some test experiments with 100 fs bunches at t-ACTS of Tohoku University. Some theoretical consideration and experiments data together with discussions will be presented.
