	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.

	A high power cyclotron is a good candidate as a driver of the accelerator driven system for the transmutation of long lived nuclear wastes. In this work, a simulation code has been developed for describing the beam dynamics in the high power cyclotron. By including higher order terms in transverse transfer matrix and space charge effects, we expect to describe the beam motion more accurately. The present code can describe equivalent orbit at each energy, calculate the tunes, and also perform multi-particle tracking. We report the initial results of the code for the simulation of a 13 MeV cyclotron. Lastly, an upgrade plan is discussed to add more features and to increase calculating efficiency.
