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. 000301901 536__ $$0G:(DE-H253)POF1-HGF-No-Prog-20130405$$aNo facility / HGF program None (POF1-890)$$cPOF1-890$$x0 000301901 588__ $$aDataset connected to INSPIRE 000301901 650_7 $$2INSPIRE$$atalk: Vienna 2000/06/26 000301901 650_7 $$2INSPIRE$$aelectron p: storage ring 000301901 650_7 $$2INSPIRE$$aluminosity: upgrade 000301901 650_7 $$2INSPIRE$$abeam transport: colliding beams 000301901 650_7 $$2INSPIRE$$abeam focusing: colliding beams 000301901 650_7 $$2INSPIRE$$abackground 000301901 650_7 $$2INSPIRE$$asynchrotron radiation 000301901 650_7 $$2INSPIRE$$agas: scattering 000301901 650_7 $$2INSPIRE$$abremsstrahlung 000301901 650_7 $$2INSPIRE$$aDESY HERA Stor 000301901 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000301901 7001_ $$0P:(DE-HGF)0$$aWilleke, F.$$b1 000301901 7870_ $$0PUBDB-2016-02907$$aDecking, Winfried$$dHamburg : DESY, 2000$$iIsPartOf$$rDESY-M-00-04; C00-06-26.2$$tContributions to the 7th European Particle Accelerator Conference EPAC 2000 000301901 8564_ $$uhttps://bib-pubdb1.desy.de/record/301901/files/DESY-M-00ZP.pdf$$yOpenAccess 000301901 8564_ $$uhttps://bib-pubdb1.desy.de/record/301901/files/DESY-M-00ZP.gif?subformat=icon$$xicon$$yOpenAccess 000301901 8564_ $$uhttps://bib-pubdb1.desy.de/record/301901/files/DESY-M-00ZP.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000301901 8564_ $$uhttps://bib-pubdb1.desy.de/record/301901/files/DESY-M-00ZP.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000301901 8564_ $$uhttps://bib-pubdb1.desy.de/record/301901/files/DESY-M-00ZP.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000301901 8564_ $$uhttps://bib-pubdb1.desy.de/record/301901/files/DESY-M-00ZP.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000301901 909CO $$ooai:bib-pubdb1.desy.de:301901$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000301901 9132_ $$0G:(DE-HGF)POF3-631$$1G:(DE-HGF)POF3-630$$2G:(DE-HGF)POF3-600$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Technologie$$vAccelerator R & D$$x0 000301901 9131_ $$0G:(DE-HGF)POF1-890$$1G:(DE-HGF)POF1$$2G:(DE-HGF)POF$$3G:(DE-HGF)POF1$$4G:(DE-HGF)POF$$9G:(DE-H253)POF1-HGF-No-Prog-20130405$$aDE-H253$$bProgrammorientierte Förderung$$lProgrammorientierte Förderung I$$vOhne Programm$$x0 000301901 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000301901 9201_ $$0I:(DE-H253)M_-2012_-20130307$$kM(-2012)$$lM-Bereich$$x0 000301901 980__ $$acontrib 000301901 980__ $$aVDB 000301901 980__ $$aUNRESTRICTED 000301901 980__ $$areport 000301901 980__ $$aI:(DE-H253)M_-2012_-20130307 000301901 9801_ $$aFullTexts
