This requires fine control of all systematic uncertainties, including the calculation of the luminosity. For this purpose, multiple independent subsystems were operated alongside the main spectrometer during data taking to allow for empirical determination of the luminosity as a function of time. An approximate value is computed based on the parameters of the lepton beam and gaseous target, while small-angle elastic scatters of known cross-section are counted by two sets of ionization-based detector systems. The most precise value comes from counting coincidences of high-rate (pure QED) lepton-lepton scatters using a pair of calorimetric lead fluoride Cherenkov detectors. 000291780 536__ $$0G:(DE-HGF)POF3-611$$a611 - Fundamental Particles and Forces (POF3-611)$$cPOF3-611$$fPOF III$$x0 000291780 588__ $$aDataset connected to DataCite, INSPIRE 000291780 650_7 $$2INSPIRE$$aluminosity 000291780 650_7 $$2INSPIRE$$across section: elastic scattering 000291780 650_7 $$2INSPIRE$$apositron p 000291780 650_7 $$2INSPIRE$$aelectron p: elastic scattering 000291780 650_7 $$2INSPIRE$$across section: ratio 000291780 650_7 $$2INSPIRE$$acalorimeter: lead 000291780 650_7 $$2INSPIRE$$alepton: beam 000291780 650_7 $$2INSPIRE$$aquantum electrodynamics 000291780 650_7 $$2INSPIRE$$aCherenkov counter 000291780 650_7 $$2INSPIRE$$atime dependence 000291780 650_7 $$2INSPIRE$$alepton lepton 000291780 650_7 $$2INSPIRE$$aspectrometer 000291780 650_7 $$2INSPIRE$$asmall-angle 000291780 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000291780 7001_ $$0P:(DE-HGF)0$$aOLYMPUS Collaboration$$b1$$eCollaboration Author 000291780 773__ $$a10.3204/DESY-PROC-2014-04/144 000291780 7870_ $$0PUBDB-2015-03603$$aSchmidt, Alexander et.al.$$dHamburg : Deutsches Elektronen-Synchrotron, DESY, Hamburg, 2014$$iIsPartOf$$rDESY-PROC-2014-04$$tProceedings, 20th International Conference on Particles and Nuclei (PANIC 14) 000291780 8564_ $$uhttps://bib-pubdb1.desy.de/record/291780/files/144.pdf$$yOpenAccess 000291780 8564_ $$uhttps://bib-pubdb1.desy.de/record/291780/files/144.gif?subformat=icon$$xicon$$yOpenAccess 000291780 8564_ $$uhttps://bib-pubdb1.desy.de/record/291780/files/144.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000291780 8564_ $$uhttps://bib-pubdb1.desy.de/record/291780/files/144.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000291780 8564_ $$uhttps://bib-pubdb1.desy.de/record/291780/files/144.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000291780 8564_ $$uhttps://bib-pubdb1.desy.de/record/291780/files/144.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000291780 909CO $$ooai:bib-pubdb1.desy.de:291780$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000291780 9131_ $$0G:(DE-HGF)POF3-611$$1G:(DE-HGF)POF3-610$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Universum$$vFundamental Particles and Forces$$x0 000291780 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000291780 9201_ $$0I:(DE-H253)ATLAS-20120731$$kATLAS$$lLHC/ATLAS Experiment$$x0 000291780 9201_ $$0I:(DE-H253)CMS-20120731$$kCMS$$lLHC/CMS Experiment$$x1 000291780 9201_ $$0I:(DE-H253)UNI_EXP-20120731$$kUNI/EXP$$lUni Hamburg / Experimentalphysik$$x2 000291780 980__ $$acontrib 000291780 980__ $$aVDB 000291780 980__ $$aUNRESTRICTED 000291780 980__ $$aintrep 000291780 980__ $$aI:(DE-H253)ATLAS-20120731 000291780 980__ $$aI:(DE-H253)CMS-20120731 000291780 980__ $$aI:(DE-H253)UNI_EXP-20120731 000291780 9801_ $$aUNRESTRICTED 000291780 9801_ $$aFullTexts
