Existing thermionic RF-gun (tungsten-BaO) at the MAX-lab linac injector has been adapted for photocathode operation (with 10 ps laser pulses at 263 nm). Important parameters of this gun for free electron laser experiments, like emittance and charge, were measured giving 5.5 mmmrad and 200 pC. Here we report more detailed on that setup, including laser and electron optics. |

A facility for seeding and harmonic generation utilizing an optical klystron is under commissioning at MAX-lab. The facility utilizes the 400 MeV linac accelerator, improved operation of an RF-gun, an undulator system of two undulators and a magnetic chicane, combined laser system for gun and seeding. The goal is to seed the electron beam at 266 nm and generate the harmonics 2-5 (133-54 nm). Currently the system is under commissioning. We report on the operation of the sub-systems and the latest results on the commissioning towards achieving harmonic generation. |

To get information about arrival of the electron bunch relative to the laser pulse; electro-optic detection scheme in crossed polarizer configuration was set up and tested. Electron bunch induced birefringence in ZnTe crystal leaves a polarization footprint in a chirped infrared pulse. IR pulse is sampled before third harmonic generation from the amplifier, stretched and synchronized to the ultraviolet beam that is used for seeding. We report details of this setup and preliminary jitter measurements. |
