A 100 MeV H-compact cyclotron is under construction at China Institute of Atomic Energy (CYCIAE-100).The proton beams of 75 MeV-100 MeV at an intensity of 200 μA will be extracted in dual opposite directions by charge exchange stripping devices.The crossing point at the switching magnet center is fixed inside the magnet yoke and the stripping points for various extraction energies are calculated by the code CYCTRS.With the code GOBLIN.we can calculate the transfer matrix including the dispersion effects from the stripping point to the switch magnet.The beam distribution just after stripping foil can be obtained from the multi-particle tracking code COMA and the extracted beam parameters after the switch magnet such as emittance,envelope,dispersion,energy spread,bunch length,etc.are given by the extraction orbit simulations.
