	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.

	Cyclotron cavity modeled via electromagnetic circuits in the desired frequency. The design performed according to resonator basis and also cyclotron acceleration requirements with ADS software and compared to simulations made by the CST microwave studio. The scattering parameters obtained for main resonators of the cyclotron and Dee parts as a diaphragm for each of cavity sections and also for the whole structure. All the characteristics modeled and calculated by the electromagnetic rules and theory of resonators from circuit model. Then it analysed with numerical methods for bench-marking. Finally, it shows that the circuit model able to modeled accurately the cyclotron cavity and especially it can estimate precisely the structure parameters without any time consuming numerical method simulations.

	In magnets for cyclotron, one of the prominent problems is difference between simulation and feasible operations. By considering more factors in simulation these differ-ence can be reduced. Thermal effect and heat transfer is one phenomenon which can change favourite features of the magnets. IRANCYC-10 is a compact AVF cyclotron which is in manufacturing phase at AmirKabir University of Technology. In IRANCYC-10 heat transfer studies have been done for RF cavity, RF transmission line and PIG ion source. In this paper, accurate simulation of heat transfer and magnetic field have been done. Also thermal effects on isochronous magnetic field for IRAN-CYC-10 is investigated. For heat transfer and CFD simu-lations, Ansys CFX and for magnetic simulation Opera 3D Tosca have been used. The initiate magnet ampere-turn in simulation is 45201 and water mass flow rate for magnet system is considered 53 lit/min.
