SIMULATION OF TWO BEAMS EXTRACTION FROM SUPERCONDUCTING CYCLOTRON C400

Superconducting cyclotron C400 [1] dedicated for acceleration of the 12 C +6 and 2 H + ions up to energy 400 MeV/nucleon is being under development at IBA (Belgium). Extraction of the carbon ions by means of electrostatic deflector (E=140 kV/cm) and protons by the help of 2 H + ions stripping were studied. These beams precise alignment at ~3 m from the cyclotron just before an energy degrader was studied as well. Number of elements in the separate extraction lines, their geometrical location, length, and value of the dipole and quadrupole component of the magnetic field inside them were determined by the help of ions tracking. Possibility of two beams extraction using partly the same extraction line was also undertaken. Extraction of ions by separate lines and their subsequent alignment to one direction using the bending magnets was found as more suitable variant. STUDY OF THE BEAM EXTRACTION POSSIBILITY IN PRINCIPAL
