Storage ring injection area upgrade at the Advanced Photon Source (APS).
Recent machine studies at the Advanced Photon Source (APS) showed that at a beam current of about 140 mA, the storage ring (SR) injection-area components experienced unacceptable elevated temperatures. Heating of these components is related to several factors, namely: aperture discontinuity, poor contact between the rf fingers and the solid sleeve liner, inadequate x-ray shielding, and nonuniform conductive coating on the kicker ceramic chambers. To address these deficiencies, we have developed design upgrades for the injection-area kicker magnets, vacuum chambers, transition absorbers, and bellows-liner assemblies. In this paper, we discuss important features of the new designs and their impact on machine operation at high beam current.
