Electro-Optical bunch length monitor for FLUTE: layout and simulations — •Andrii Borysenko1, Edmund Hertle1, Nicole Hiller1, Vitali Judin1, Sebastian Marsching1, Anke-Susanne Müller1, Michael Johannes Nasse1, Markus Schwarz1, and Bernd Steffen2 — 1KIT, Karlsruhe, Germany — 2DESY, Hamburg, Germany
A new compact linear accelerator FLUTE is currently under construction at Karlsruhe Institute of Technology (KIT) in collaboration with DESY and PSI. It aims at obtaining femtosecond electron bunches (~1fs - 300 fs) with a wide charge range (1 pC - 3 nC) and requires a precise bunch length diagnostic system. Here we present the layout of a bunch length monitor based on the electro-optic technique of spectral decoding using an Yb-doped fiber laser system (central wavelength 1030 nm) and a GaP crystal. Simulations of the electro-optic signal for different operation modes of FLUTE were performed and main challenges are discussed in this talk. This work is funded by the European Union under contract PITN-GA-2011-289191
