FLASH2 will offer up to six additional photon beamlines in the new experimental hall 'Kai Siegbahn'. Photon beam parameters can be chosen almost independently for FLASH1 and FLASH2 by the users. FLASH2 has variable gap undulators and thus, the wavelength of FLASH2 can be chosen independent from FLASH1. In addition, fast tuning of the wavelength as well as wavelength scans are possible at FLASH2. Each undulator line has its own injector laser and thus bunch separation, number of bunches, and the bunch charge can be set independently for FLASH1 and FLASH2. Both undulator lines receive the full 10 Hz bunch train repetition rate, but each 800 microsecond long burst is split between FLASH1 and FLASH2. The fraction of bunches delivered to each beamline can be chosen freely. A new, much more flexible RF-system allows different compressions for FLASH1 and FLASH2, and therefore a different photon pulse length can be chosen by either user.
The following new beamlines at FLASH2 are available for users since spring 2016 in the FLASH experimental hall 'Kai Siegbahn':
FL24 has an open port for user supplied end stations. FL24 covers the entire wavelength range of FLASH2 (see FLASH parameters) and is equipped with a KB bending mirror system for focussing.
FL26 features the permanent end station REMI - a reaction microscope from R. Moshammer's group at MPIK Heidelberg.
