Abstract:The free-electron laser of the TEU-FEL project of the University of Twente will be driven by a photoinjector followed by a racetrack microtron. The injector, which is now under construction, will provide a very high-brightness electron beam with an energy of about 6 MeV. In phase I of the project, experiments are being planned in which this low energy beam from the injector will pass through an undulator and will generate radiation at a wavelength of about 200 ¿m via the process of self-amplified spontaneous emission (SASE). Numerical simulations of the performance of this source indicate that power levels of about 15 MW (averaged over a micropulse) can be obtained with a 1-m undulator. We present additional results derived from simulation studies of the performance of this device.
