Bunch length measurement in linac can be carried out using a Radio Frequency Deflector (RFD).

Abstract
Bunch length measurement in linac can be carried out using a Radio Frequency Deflector (RFD). A RFD provides a transverse kick to the beam introducing a correlation between the longitudinal coordinate of the bunch and the transverse coordinates, vertical or horizontal. So, through transverse beam size measurement on a screen, placed after the RFD, the bunch length can be obtained. In this paper, the metrological characterization of the bunch length measurement technique is proposed. The uncertainty and the systematic errors are estimated by means of a sensitivity analysis performed on the measurement parameters. The proposed approach has been validated through simulation by means of ELEctron Generation ANd Tracking (ELEGANT) code on the parameters interesting for the electron linac of the Compton source at the Extreme Light Infrastructure - Nuclear Physics (ELI-NP). © 2016, IMEKO-International Measurement Federation Secretariat.
