Abstract :
Fast pulsed kicker magnets will be used in the Advanced Light Source (ALS) Booster to accept injected 50-MeV electrons from the source linac and then eject the full energy 1.5-GeV beam into the storage ring. Their design has incorporated a number of unique elements to achieve the tight requirements for efficient beam transfer. The booster orbit time of 250 ns and a maximum of 12 electron bunches, spaced 8 ns apart, define the maximum required injection and extraction kicker magnet flat top time. A 100-ns injection falltime and extraction risetime were selected, with the 50-ns balance left for pulse setting and timing errors. The injected beam is deflected 59 mrad and the extracted beam 4 mrad. This can be accomplished with a 0.5-m 200-G magnet for injection and a 1-m 200-G magnet for extraction. A uniformity of ±0.5% temporally and spatially is required of the nominal 200-G flat top field to maintain a low loss/dispersion system
