Description

Considering that a relative positioning accuracy of {+-}0.09mm in the lateral direction and {+-}0.07mm in the vertical direction has been achieved, and taking into account the standard deviation for the determination of the magnetic center versus the mechanical center of {+-}0.075mm, the position between magnet centers is estimated to be within {+-}0.125mm less than the required {+-}0.150mm. The successful alignment of the APS storage ring is also documented by the rapid progress in the commissioning program. Shortly after the start of the storage ring commissioning phase, the beam was transported around the entire ring without the use of correctors. Multiple ... continued below

Description

Considering that a relative positioning accuracy of {+-}0.09mm in the lateral direction and {+-}0.07mm in the vertical direction has been achieved, and taking into account the standard deviation for the determination of the magnetic center versus the mechanical center of {+-}0.075mm, the position between magnet centers is estimated to be within {+-}0.125mm less than the required {+-}0.150mm. The successful alignment of the APS storage ring is also documented by the rapid progress in the commissioning program. Shortly after the start of the storage ring commissioning phase, the beam was transported around the entire ring without the use of correctors. Multiple turns were recorded shortly thereafter and rf capture of the beam has been demonstrated. In March 1995, only two months after the start of the commissioning phase, the first X-ray light produced by a bending magnet was recorded, and during August the first undulator to produce X-ray light was installed. The present goal is to achieve higher beam current and a longer beam lifetime with an improved vacuum.
