Sflash - First results of direct seeding at flash
(2011) 25th International Linear Accelerator Conference, LINAC 2010 p.419-421- Abstract
The free-electron laser facility FLASH at DESY (Hamburg) was upgraded during a five month shutdown in winter 2009 [1]. Part of this upgrade was the installation of a direct seeding experiment in the XUV spectral range. Besides all components for transport and diagnostics of the photon beam into and out of the accelerator environment, a new 10m long variable-gap undulator was installed upstream of the existing FLASH undulator system. The seed pulses are generated within a noble-gas jet by focusing 40 fs long Ti:Sa laser pulses into it, resulting in a comb of higher harmonics. In the first phase of the experiment, the 21st harmonic at about 38 nm will be used to seed the FEL process. The commissioning of the experiment has started in... (More)
The free-electron laser facility FLASH at DESY (Hamburg) was upgraded during a five month shutdown in winter 2009 [1].

The seed pulses are generated within a noble-gas jet by focusing 40 fs long Ti:Sa laser pulses into it, resulting in a comb of higher harmonics. In the first phase of the experiment, the 21st harmonic at about 38 nm will be used to seed the FEL process. The commissioning of the experiment has started in April. All hardware components are in operation and first seeding is expected for end of September 2010. The experimental setup and the commissioning procedures as well as first result are presented.
