| 520 | _ | _ | |a DESY pursues a luminosity upgrade project [1] for the HERA electron proton collider with the goal to raise the luminosity by a factor 5 compared to original design parameters. The major part of this increase is achieved by installing new interaction regions in 2000/2001. The new scheme involves a very early separation of the colliding beams by means of superconducting magnets that are installed inside the experimental detectors. The early beam separation allows to position the final focus quadrupoles closer to the IP, which in turn leads to smaller beam spotsizes and higher luminosity.The beam separation inside the detectors causes two major problems. About 28kW of synchrotron radiation power is produced in the separation magnets, i.e. in the detectors. Secondly the strong bending magnets tend to deflect low energy electrons, produced by beam-gas bremsstrahlung interactions, onto the detector beampipe. Both effects present qualitatively new background sources for the detectors. We describe how these problems are counteracted with the specifically adopted layout of the geometry and the vacuum system in the new interaction regions. |
