Advanced applicatons of the FLASH laser heater for short-pulse generation — •Carsten Mai1, Philipp Amstutz1, Shaukat Khan1, and Christopher Gerth2 — 1Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany — 2Deutsches Elektronen Synchrotron DESY, Hamburg, Germany
Laser heaters at FEL facilites are used to increase the electron energy spread and suppress the microbunching instability. A laser-heater has been installed as part of the FLASH2020+ upgrade program upstream of the first bunch compressor chicane at FLASH. As an extension of the standard laser heater operation, the FLASH Laser-Assisted Reshaping of Electron bunches (FLARE) project aims at the generation of short pulses by using the laser heater in an advanced configuration. Two different methods for the variation of the pulse duration using the laser heater and first measurements are presented.
