November 1988DISTRIBUTION OF THE SYNCHROTRON RADIATION
FROM BENDING MAGNETS
This note describes the distribution of the synchrotron radiation
from the bending magnets (BM) around the vacuum chamber, crotches, and
absorbers in the storage ring of the Advanced Photon Source (APS).
The layout of a 26.5-m-long sector of the Chasman-Green lattice for
the APS is shown in Fig. 1 with the locations of BM (M1, M2), crotches (Cl,
C2), and absorbers (A1-A4). There are additional absorbers near the locations
of Cl and C2. The source of the BM beam line is the M2 magnet. Bending
magnets M1 and M2 are of the same kind, being distinguished because of their
different locations with respect to the straight section. The relevant
storage-ring parameters used in this note, listed below, are for the maximum
level of the radiation:Positron Beam Energy
