Two electrostatic deflectors are used for beam extraction of the 230 MeV superconducting cyclotron CYCIAE-230, which is under development at CIAE. Resonance crossing and processional motion are introduced by a first harmonic bump of main field during the beam dynamics design to increase the turn separation and accordingly the extraction efficiency. Four trim-rods of variable depth are employed to generate the desirable field bump for their stability, the amplitude and azimuth of first harmonic bump can be adjusted with different size and depth of trim-rods. However, effect on isochronous field in acceleration region is followed by trim-rods in practice, therefore the base depth of trim-rods need to be designed and re-shimming procedure of main magnet model need to be implemented interactively. The effect of trim-rods and isochronous field production by a new model will be presented in this paper.

OPAL (Object Oriented Parallel Accelerator Library) is a open source tool for charged-particle optics calculations in accelerator structures and beam lines including 3D space charge, short range wake-fields, 1D coherent synchrotron radiation and particle matter interaction. OPAL admits simulations of any scale, from the laptop to the largest HPC clusters. OPAL has a fast FFT based direct solver and an iterative solver with AMR, able to handle efficiently exact boundary conditions on complex geometries. We will discuss new capabilities such as Graphical Processing Units (GPUs) support, turning your workstation into a super computer, time dependent fields necessary for modelling FFAGs, synchrotrons and synchro-cyclotrons and the creation of matched distributions with linear space charge.
