Abstract

A 10 MeV travelling wave linac will be used as injector for the 10-75 MeV racetrack microtron Eindhoven. The six dimensional emittance of the linac will be matched to the acceptance of the microtron. In longitudinal phase space the negative dispersive action of the first bend in the racetrack microtron is counteracted by the dispersive action of the doubly achromatic bending section in the transport line. The data for the longitudinal emittance are obtained from numerical simulations. The energy spread of the initial beam is larger than the energy acceptance of the racetrack microtron. It will be reduced with a slit system in a dispersive section of the transport line
