COMMISSIONING OF THE TEST FEL AT MAX-LAB

In English An installation for testing techniques related to seeding
and harmonic generation has been completed at MAXlab.
The aim is to study the processes around seeded
harmonic generation at 130/88/54 nm, the 2/3/5 harmonic
of a Ti:Sapphire laser. During the spring 2008 the
commissioning work has begun and this paper will report
on the progress.
The test FEL is built around the existing linac injector at
MAX-lab. This source can provide 4-500 MeV electrons
from an RF-gun. A combined laser system both driving
the photo cathode in the gun and, synchronised via an
optical fibre, the seed laser pulse has been put into
operation. An optical klystron, consisting of two 30
period undulators and a 4-magnet chicane, is in operation.
Beam loss monitors along the optical klystron are in use
and a THz system for additional synchronisation studies
installed.
Results from electron beam optics and operation
generating spontaneous radiation is already available and
synchronisation results immediate. The work is in
progress and new results are added continuously to the
portfolio.
