Abstract :
A generic method of LEBT automatic tuning is under development that can be applied toward any pulsed beam accelerator using a radio frequency quadrupole (RFQ) with an adjustable solenoid-type LEBT. The purpose of this control scheme is to self-optimize the beam transport through the RFQ for any operating condition of the accelerator. This system is useful for an accelerator that operates over a range of currents. For a constant current machine, the system is useful to dynamically correct any drifts with time. This system is being developed on a beamline that uses a dual solenoid LEBT; however, the same system can also be used on a beamline with a single solenoid. This paper describes the mechanical and electrical design of the system and the algorithms used for the tuneup
