Diagnostic Tools for the Undulator System of the Seeded HGHG-FEL at MAX-lab
(2008) 30th International Free Electron Laser Conference, 2008 p.243-246- Abstract
- Within a collaboration between MAX-lab and BESSY
a one stage seeded HGHG-FEL has been set up at Maxlab.
BESSY has built the undulator system consisting of a
modulator, a radiator and an electromagnetic chicane.
BESSY has also installed three types of diagnostic tools:
optical fibres for a fast Cherenkov beam loss detection,
optical fibres for absolute dose measurements via their
radiation-induced attenuation and THz detectors for the
characterization of electron bunch properties. During first
injections with a laser driven rf-gun the Cherenkov fibres
have delivered detailed spatial information on the beam
losses inside the beamline. Over the... (More) - Within a collaboration between MAX-lab and BESSY

system, based on powermeter measurements, has detected
a total dose of 180Gy. The high sensitivity and low drift
of this system has been demonstrated. A THz detector
behind the last dipole magnet close to the beam dump
provides information on the bunch compression and the
laser induced energy modulation. We report on the
measurements performed with these diagnostics tools. (Less)
