Beam Dynamics Studies of ECR Injections for the Coupled Cyclotron Facility at NSCL
The Coupled Cyclotron Facility(CCF)has been operating at the NSCL since 2001, providing up to 160MeV/u heavy ion beams for nuclear physics experiments.Recent steps,particularly the improvement of the ECR-to-K500 injection line,were taken to improve the CCF performance.For that purpose an off-line ECR source.ARTEMIS-B,was built and used to investigate the impact on beam brightness under various source operating conditions,different initial focusing systems and current analysis dipole.Beam dynamics simulations including space-charge and 3D electrostatic field effects were performed and beam diagnostics including emittance scanner were used,leading to a better understanding of the CCF beam injection process New initial electrostatic focusing elements such as a large-bore quadrupole triplet and a quadrupole doubledoublet with compensating octupole were tested,and a new beam tuning procedure was established to improve the beam brightness for the CCF. Following these efforts,a significant increase of primary beam power out of the CCF has been achieved.
