There are also 80m of damping wigglers in order to achieve a low emittance of 1nmrad. Some of these devices, operating at PETRAIII since 2008, accumulated totalradiation doses of about 100kGy.Visible corrosion at the magnet structures of some permanent magnet undulators setting in after a few years and a high dose rate measured regularly by thermoluminescent dosimeters (TLDs) gave reason to inspect the magnetic field of all insertion devices in the PETRA tunnel. This paper presents details of the magnetic field degradation caused byradiation damage to the undulator magnets. For some undulators changes in the spectral properties of the generated light were observed. It was measured with different taper settingsin order to partly compensate the nonuniform demagnetization along the structure. The results are compared with the data from the sFLASH undulators and measurements of special 3 pole "sacrificial" undulator, installed in FLASH. Its magnetic field is periodically remeasured and shows field amplitude decrease of 1% per 16kGy accumulated dose. 000205487 536__ $$0G:(DE-HGF)POF3-6G3$$a6G3 - PETRA III (POF3-622)$$cPOF3-622$$fPOF III$$x0 000205487 588__ $$aDataset connected to DataCite 000205487 650_7 $$2Other$$aAccelerator Physics 000205487 650_7 $$2Other$$a02 Synchrotron Light Sources and FELs 000205487 650_7 $$2Other$$aT15 Undulators and Wigglers 000205487 693__ $$0EXP:(DE-H253)PETRAIII(machine)-20150101$$1EXP:(DE-H253)PETRAIII-20150101$$5EXP:(DE-H253)PETRAIII(machine)-20150101$$aPETRA III$$eFacility (machine) PETRA III$$x0 000205487 7001_ $$0P:(DE-H253)PIP1014763$$aBilani, Orkidia$$b1 000205487 7001_ $$0P:(DE-H253)PIP1000495$$aSchoeps, Andreas$$b2$$udesy 000205487 7001_ $$0P:(DE-H253)PIP1015712$$aTripathi, Sumit$$b3 000205487 7001_ $$0P:(DE-H253)PIP1001322$$aVielitz, Thorsten$$b4 000205487 7001_ $$0P:(DE-H253)PIP1001383$$aTischer, Markus$$b5 000205487 773__ $$a10.18429/JACoW-IPAC2014-WEPRO035 000205487 7870_ $$0PUBDB-2017-144829$$aPetit-Jean-Genaz, Christine et.al.$$dGeneva : JACoW, 2014$$iIsMemberOf$$r$$tParticle accelerator 000205487 8564_ $$uhttp://accelconf.web.cern.ch/AccelConf/IPAC2014/papers/wepro035.pdf 000205487 8564_ $$uhttps://bib-pubdb1.desy.de/record/205487/files/wepro035.pdf$$yOpenAccess 000205487 8564_ $$uhttps://bib-pubdb1.desy.de/record/205487/files/wepro035.gif?subformat=icon$$xicon$$yOpenAccess 000205487 8564_ $$uhttps://bib-pubdb1.desy.de/record/205487/files/wepro035.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000205487 8564_ $$uhttps://bib-pubdb1.desy.de/record/205487/files/wepro035.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000205487 8564_ $$uhttps://bib-pubdb1.desy.de/record/205487/files/wepro035.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000205487 909CO $$ooai:bib-pubdb1.desy.de:205487$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000205487 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1008615$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000205487 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1014763$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000205487 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1000495$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000205487 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1015712$$aExternes Institut$$b3$$k>Extern 000205487 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1001322$$aDeutsches Elektronen-Synchrotron$$b4$$kDESY 000205487 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1001383$$aDeutsches Elektronen-Synchrotron$$b5$$kDESY 000205487 9131_ $$0G:(DE-HGF)POF3-622$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G3$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Research on Matter with Brilliant Light Sources$$x0 000205487 9132_ $$0G:(DE-HGF)POF3-622$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$9G:(DE-HGF)POF3-6G3$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Research on Matter with Brilliant Light Sources$$x0 000205487 9141_ $$y2014 000205487 915__ $$0LIC:(DE-HGF)CCBY3$$2HGFVOC$$aCreative Commons Attribution CC BY 3.0 000205487 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000205487 9201_ $$0I:(DE-H253)FS-US-20120731$$kFS-US$$lFS-Undulator Systeme$$x0 000205487 980__ $$acontrib 000205487 980__ $$aVDB 000205487 980__ $$acontb 000205487 980__ $$aI:(DE-H253)FS-US-20120731 000205487 980__ $$aUNRESTRICTED 000205487 9801_ $$aFullTexts
