Racetrack microtron (RTM) is a compact accelerator to obtain electron beams with an energy above 100 MeV. Conventional RTM's have been designed to accelerate a train of electron bunch from a thermionic electron gun, where the bunch charge is typically 10 pC. In the industrial application of laser Compton scattered gamma-ray sources, RTM with 200-300 MeV electron energy will be a suitable device to produce 2-3 MeV gamma-ray beams. Single electron bunch from a photocathode RF gun is accelerated and a high-charge small-emittance beam is preferable in such RTM. In this paper, we adopt a simulation code, GPT, for design and optimization of RTM in view of high-charge and small-emittance beam generation.

We have developed a laser Compton scattered gamma-ray source based on a 150-MeV racetrack microtron at Japan Atomic Energy Agency. The microtron equipped with a photocathode RF gun accelerates a single bunch of electrons to collide with a laser pulse from a Nd:YAG laser. Such gamma-ray source realizes industrial application of nuclear material detection in a ship cargo, which is one of the urgent requests of international nuclear security. Recent status of gamma-ray generation experiments and design study of a practical machine is presented.
