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.
