Description

A raster magnet was installed to rotate the 500 MeV proton beam onto the TRIUMF ISAC target. Rotating the proton beam produces a more uniform average power deposition, which increases the amount of beam power that targets can take. 
The magnet system is a pair of two ferrite AC magnets which rotates the proton beam at a frequency up to 400 Hz, for various deflection angles. A new tune was developed to produce a controllable spot size, while having an approximate parallel beam on target and a 90 degrees phase advance between the raster magnets and the target. A set of diagnostics was developed to monitor the rotating beam. Online tests have shown that we can increase the RIB yields from a target for the same maximum temperature. In addition this method simplifies beam delivery by making beam size adjustments more predictable and straightforward.
