	We report on the tuning of end magnets of a compact 12 MeV racetrack microtron (RTM) which is under construction at the Technical University of Catalonia. They are magnetic systems composed of four dipoles with the Rare-Earth Permanent Magnet (REPM) material used as a source of the magnetic field. The poles of the magnets are equipped with tuning plungers which allow to adjust the magnetic field level. In the article we describe the tuning procedure and different techniques that were used in order to fulfill strict requirements of the field characteristics of the end magnets. It is shown that the obtained magnetic systems provide correct beam trajectories in the 12 MeV RTM.

	A compact 12 MeV race-track microtron which is under construction at the Technical University of Catalonia includes a quadrupole magnet for horizontal beam focusing and four dipoles for beam extraction. As the source of the magnetic field in these magnets a Rare-Earth Permanent Magnet (REPM) material is used. In the article the main design characteristics of the quadrupole lens and extraction dipoles are described and a procedure of tuning of their magnetic fields is discussed. We report on the manufacturing of these magnetic systems and results of the tuning of their magnetic fields.

WEPRO004	Status of Laser Compton Scattered Gamma-ray Source at JAEA 150-MeV Microtron	laser, radiation, detector, electron	1943
	R. Hajima JAEA/ERL, Ibaraki, Japan I. Daito, H. Negm, H. Ohgaki Kyoto University, Kyoto, Japan M. Ferdows, T. Hayakawa, M. Kando, T. Shizuma JAEA, Ibaraki-ken, Japan
	Funding: This work is supported by Funds for Integrated Promotion of Social System Reform and Research and Development. 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.

THPPA03	The MAX-lab Story; From Microtron to MAX IV	synchrotron, electron, storage-ring, synchrotron-radiation	2852
	M. Eriksson MAX-lab, Lund, Sweden
	The MAX story started with the design and construction of a small Race-Track Microtron 1973-1979. This microtron was later followed by the synchrotron radiation storage rings MAX I, MAX II, MAX III and the MAX IV facility, the latter consisting of two storage rings operated at 1.5 and 3 Gev respectively and also including a full energy injector linac. It was quite clear from the very beginning that conventional accelerator technology not was matching the boundary conditions in terms of the staff size and limited economical resources at MAX. We had to find new technical solutions based on mass-produced industrial components and an extensive usage of CNC machining to match the turbulent development of synchrotron radiation sources. This article describes some of the most important features of the accelerators developed at MAX-lab and covers also the design philosophy behind the early ideas for designing a close to Diffraction Limited Storage Ring. Finally, the author and MAX staff wants to thank the prize committee for the prestigious Wideröe prize and thank all our international colleagues world-wide.

	A simple control system has been developed for the commissioning of a compact 12 MeV race-track microtron which is under construction at the Technical University of Catalonia. It is of modular structure and is based on LabView programs at a conventional PC and ATmega microcontrollers. Apart from modules to monitor different RTM systems it also includes an Automatic Frequency Control of the magnetron frequency and interlocks. The architecture and main features of the modules are described and results of their operation are reported. Further developments of the control system and interfaces are on the way.
