This paper outlines a general beamline smoothing concept based on the use of
First Principle
Component analysis. Beamline smoothing is commonly used for the detection of blunders in the positioning of beam elements and to provide a smooth particle beam path with the fewest adjustments to individual beam components. It also provides the data for assessment of the achieved positioning quality. I. INTRODUCTION During the last three years the
Advanced Photon Source
(APS) has been under construction at Argonne National Laboratory. The APS is a 7-GeV synchrotron light source which is being used for
basic research
in material science, chemistry, physics, biology, and medicine. The APS consists of a 70m-long linear accelerator, a
positron accumulator ring
(PAR), a synchrotron ring (SY) with a circumference of 368m, and the
storage ring
(SR) with a circumference of 1104m (Fig. 1). The 40m electron linac uses 200-MeV electrons for the production of positrons. In the 30m-long
linear accelerator
section following the electron linac, the particles gain a mass of 450 MeV before entering the positron accumulator ring. From there the beam is injected into the booster synchrotron which accelerates the positrons from 450 MeV to 7 GeV before entering the storage ring. The
storage ring
can accommodate up to 68 x-ray beamlines.
