Possible Scheme of the Analyzing Part of a Cyclotron Injection Beamline with Higher Energy

Ion source extraction potentials are often in the range of 10 - 30 kV where space-charge forces are detrimental to beam quality. Use of higher extraction voltage results in reduced space-charge effects but may be too high for subsequent injection. A scheme of beam extraction at 50 kV followed by dec...

Description
Summary:Ion source extraction potentials are often in the range of 10 - 30 kV where space-charge forces are detrimental to beam quality. Use of higher extraction voltage results in reduced space-charge effects but may be too high for subsequent injection. A scheme of beam extraction at 50 kV followed by deceleration to 25 kV is considered. Simulation results with an argon beam in such a beam line are presented.
