	Designing and manufacturing of the 18 MeV cyclotron has been started for producing H⁻ for applications in Posi-tron Emission Tomography (PET) radioisotopes at Amirkabir University Of Technology. Up to this point, there were 2 steps in magnet design: Initial design and optimization processes. The AVF structure with hill and valley was selected for getting strong axial focusing in magnet design and achieving up to 18MeV energy for the particle. After finishing the initial design, optimization process in magnet design was started for achieving the best coincidence in magnetic field. Checking the beam dynamic of the particle is one of the most important and necessary steps after magnet simulation. The phenomenon which confirms simulated magnet validity is obtaining reasonable particle trajectory. This paper focused on the optimization process in magnet design and simulation of the beam dynamic. Some results which ensure a particle can be accelerated up to 18 MeV energy, are presented. All magnetic field calculation in whole magnet was calculated by OPERA-3D(TOSCA) code. Also beam dynamic analysis by applying magnetic field data from the magnet simulation was done in CYCLONE code.

TUP25	The Methods of Compensation of the Beam Vertical Divergence at the Exit of Spiral Inflector in Cyclotrons	cyclotron, ion, quadrupole, operation	221
	I.A. Ivanenko JINR, Dubna, Moscow Region, Russia
	While the axial injection into the cyclotron, the beam is turned from axial direction into median plane by means of inflector. Commonly used type of inflector is an electrostatic spiral inflector. The spiral inflector is easy to handle and has a good beam transmission factor. On the other hand, the negative feature of spiral inflector is the beam vertical divergence at the exit of inflector. It leads to increasing of beam vertical dimension and aperture losses at the first orbits. The methods of compensation of the beam vertical divergence at the inflector exit are considered at present report. This methods are used at FLNR JINR cyclotrons and give a good results in transmission factor, beam quality and operation modes.

	Funding: TRIUMF also receives federal funding via a contribution agreement through the National Research Council of Canada. We present a method to improve computation efficiency of space charge simulations in cyclotrons. This method is particularly efficient for simulating long bunches where length is large compared to both transverse size and turn separation. We show results of application to space charge effects in the TRIUMF 500 MeV cyclotron.
