    Abstract

    At the superconducting LINAC of FLASH, we have installed an electro-optic experiment for single shot, nondestructive measurements of the longitudinal distribution charge of individual electron bunches. The profile of the electron bunch field is electro-optically encoded onto a stretched Ti:Sa laser pulse. In the decoding step, the profile is retrieved either from a spectral measurement of the encoded pulse or from a cross-correlation of the encoded pulse with a 30 fs FWHM laser pulse, obtained from the same laser pulse. At FLASH, sub-100 fs electron bunches has been measured during FEL operation with an rms value of 60 fs (144 FWHM). The electro-optic measurements have been validated with transverse deflecting structure measurements.
