Description
Sichuan Longevous Beamtech is currently developing a new tri-particle cyclotron LB-30TP. The LB-30TP cyclotron is designed to be able to accelerate protons(H-) between 13 and 35MeV, deuterons(D-) between 6.5 and 17.5MeV, and alpha particles(He2+) up to 30MeV.
The proton and deuteron beams are generated by a multi-cusp ion source, while the alpha particle beams are generated by an ECR ion source. These two ion sources are located on two sides above (or below) the cyclotron, and the ion beams extracted from them are both transported through a primary focusing solenoid and combined by a dipole before entering the injection beam line. The injection beam line consists of a quadrupole triplet, a steering magnet, a solenoid and a quadrupole doublet, and the matching between the beam emittance and the acceptance at the entrance of the spiral inflector is achieved by optimizing the parameters of these magnetic components. The spiral inflector and the central region electrodes are optimized to achieve high injection efficiency and good orbit centering.
