The baseline design plans to use the electron beam for the positron production before it goes to the IP. The high-energy electrons pass a long helical undulator and generate an intense circularly polarized photon beam which hits a thin conversion target to produce $e^+e^-$ pairs. The resulting positron beam is longitudinally polarized which provides an important benefit for precision physics analyses. In this paper the status of the design studies is presented with focus on ILC250. In particular, the target design and cooling as well as issues of the optical matching device are important for the positron yield. Some possibilities to optimize the system are discussed. 000425664 536__ $$0G:(DE-HGF)POF3-611$$a611 - Fundamental Particles and Forces (POF3-611)$$cPOF3-611$$fPOF III$$x0 000425664 588__ $$aDataset connected to INSPIRE 000425664 693__ $$0EXP:(DE-H253)ILC(machine)-20150101$$1EXP:(DE-H253)ILC-20150101$$5EXP:(DE-H253)ILC(machine)-20150101$$aILC$$eFacility (machine) ILC$$x0 000425664 7001_ $$0P:(DE-H253)PIP1011115$$aMoortgat-Pick, Gudrid$$b1$$udesy 000425664 7001_ $$0P:(DE-H253)PIP1003733$$aRiemann, Sabine$$b2$$eCorresponding author$$udesy 000425664 7001_ $$aSievers, Peter$$b3 000425664 7001_ $$aUshakov, Andriy$$b4 000425664 8564_ $$uhttps://bib-pubdb1.desy.de/record/425664/files/1902.07744v1.pdf$$yOpenAccess 000425664 8564_ $$uhttps://bib-pubdb1.desy.de/record/425664/files/1902.07744v1.gif?subformat=icon$$xicon$$yOpenAccess 000425664 8564_ $$uhttps://bib-pubdb1.desy.de/record/425664/files/1902.07744v1.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000425664 8564_ $$uhttps://bib-pubdb1.desy.de/record/425664/files/1902.07744v1.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000425664 8564_ $$uhttps://bib-pubdb1.desy.de/record/425664/files/1902.07744v1.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000425664 8564_ $$uhttps://bib-pubdb1.desy.de/record/425664/files/1902.07744v1.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000425664 909CO $$ooai:bib-pubdb1.desy.de:425664$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000425664 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1011115$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000425664 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1003733$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000425664 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 000425664 9141_ $$y2019 000425664 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000425664 9201_ $$0I:(DE-H253)ZEU-DLAB-20130226$$kZEU-DLAB$$lbeauftragt von ZEU-SEK$$x0 000425664 980__ $$apreprint 000425664 980__ $$aVDB 000425664 980__ $$aUNRESTRICTED 000425664 980__ $$areport 000425664 980__ $$aI:(DE-H253)ZEU-DLAB-20130226 000425664 9801_ $$aFullTexts
