Abstract:A racetrack microtron as a source for a free electron laser is being constructed. It will accelerate electrons up to 25 MeV to provide 10 ¿m radiation in a hybrid undulator with a periodicity distance of 25 mm. The aim is to accelerate 100 A bunches of 30 ps pulse length at 81.25 MHz. This frequency is chosen to minimize cavity loading, by avoiding simultaneous presence of more than one bunch in the microtron cavity. The self-focusing longitudinal action of the microtron assures a small energy and phase spread of the outcoming beam. Transverse focusing will be provided by applying edge focusing at valley boundaries in the sector magnets. An analytical theory and computer simulations have been set up and are being further developed for studying the effects of space charge during acceleration. Details of calculations and construction will be given.
