This paper is a description of the computer simulation and the first experimental results on an AIC-144 isochronous cyclotron new extraction system. The cyclotron will be able to generate beams of protons, deuterons and alfa particles. One of the principal goals of the upgraded facility is to extract beams of protons and deuterons (proton energy 60 MeV, deuteron energy 30 MeV) for proton radiotherapy and for fast neutron beams. The precession method for particle extraction was chosen as the best one. It is the first time that the proton beam of energy 35 MeV has been extracted from the AIC-144 cyclotron with an efficiency of above 50%. More careful adjustment of the extraction system parameters (better control of the 1st harmonic of the magnetic field and the position of the deflectors) will permit an increase in the extraction efficiency to the design value of 70%.
