Advanced applications of laser heaters — •Linus Bölte¹, Philipp Amstutz², Christopher Gerth², Shaukat Khan¹, and Carsten Mai¹ — ¹Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany — ²Deutsches Elektronen Synchrotron DESY, Hamburg Germany

Many FEL facilities use laser heaters to increase the electron energy spread and hence suppress microbunching instabilities. As part of the FLASH2020+ upgrade at DESY, a laser heater has been installed upstream of the first bunch compressor chicane. The goal of the FLASH Laser-Assisted Reshaping of Electron bunches (FLARE) project is to implement energy modulation schemes expanding the laser heater's basic purpose. This includes intentionally overheating regions of the electron bunch, as well as an up to now untested bunch compression method that will allow the generation of tunable few-femtosecond and possibly sub-femtosecond electron distributions. First studies on advanced applications of the laser heater will be presented.
