“…The commissioning of the Advanced Photon Source ( A P S ) 7-GeV storage ring (SR) was supported by a full complement of diagnostics subsystems (1)(2)(3). Both the machine and, in some cases, specific features of the diagnostics systems were evaluated and demonstrated in a phased manner.…”

Abstract. Initial comgissionings of the Advanced Photon Source (APS) 7-GeV storage ring and its diagnostics systems have bwn done. Early studies involved single-bunch measurements for beam transverse size (ox 150 pm, oy = 50 pm), current, injection losses, and bunch length. The diagnostics have been used in studies related to the detection of an extra contribution to beam jitter at -6.5 Hz frequency; observation of bunch lengthening ((3 = 30 to 60 ps) with single-bunch current; observation of an induced vertical, head-tail instability; and detection of a small orbit change with insertion device gap position. More recently, operations at 100-mA stored-beam current, the baseline design goal, have been achieved with the support of beam characterizations.

Abstract, Two photon monitors have been designed and installed in the positron accumulator ring (PAR) of the Advanced Photon Source. The photon monitors characterize the beam's transverse profile, bunch length, emittance, and energy spread in a nonintrusive manner. An optical transport line delivers synchrotron light from the PAR out of a high radiation environment. Both charge-coupled device and fast-gated, intensified cameras are used to measure the transverse beam profile (0.1 1-1 mm for damped beam) with a resolution of 0.06 mm. A streak camera (GZ =1 ps) is used to measure the bunch length which is in the range of 0.3-1 ns. The design of the various transport components and commissioning results of the photon monitors will be discussed.
