abstract = {In the upgraded HERA interaction regions, about 30kW of
synchrotron radiation have to be passed safely through the
high energy physics detectors. At a distance of about 11m
from the interaction point a fraction of this synchrotron
radiation is absorbed, while the remaining part is passed
further on through the separated beam pipes. To protect the
vacuum chamber between the IP and the 11m absorber against
accidential mis-steering of the synchrotron radiation fan,
four emergency absorbers are installed. On the other hand
the HERA detectors are very sensitive to backgrounds from
backscattered synchrotron radiation photons. The aperture of
absorbers and other elements in the downstrem beamline have
to be chosen such as to guarantee acceptable background
conditions even with moderately missteered electron beams.
To investigate the feasibility of this scheme, extensive
simulations have been carried out taking into account
realistic machine errors, such as magnet misalignments,
monitor errors, optics distortions, etc. It is shown that
under realistic conditions the synchrotron radiationfan can
be safely controlled.},
