This upgraded facility will offer simultaneous seeded and SASE pulses. Introducing a chirped electron bunch and high repetition rate seed lasers with unique spectral features will significantly influence the electron bunching and the spectral properties of the output. This work discusses our computational modeling strategies for aligning theoretical predictions closely with anticipated experimental outcomes, focusing on the dynamics of chirped bunch interactions with beamline instability and some of their effect on the FEL outputs. 000614238 536__ $$0G:(DE-HGF)POF4-6G2$$a6G2 - FLASH (DESY) (POF4-6G2)$$cPOF4-6G2$$fPOF IV$$x0 000614238 536__ $$0G:(DE-HGF)POF4-621$$a621 - Accelerator Research and Development (POF4-621)$$cPOF4-621$$fPOF IV$$x1 000614238 693__ $$0EXP:(DE-H253)FLASH2020p-20221201$$1EXP:(DE-H253)FLASHII-20150901$$5EXP:(DE-H253)FLASH2020p-20221201$$aFLASH II$$eFLASH 2020+ Project$$x0 000614238 7001_ $$0P:(DE-H253)PIP1008868$$aAckermann, Sven$$b1 000614238 7001_ $$0P:(DE-H253)PIP1100127$$aFerrario, Eugenio$$b2 000614238 7001_ $$0P:(DE-H253)PIP1024674$$aLang, T.$$b3 000614238 7001_ $$0P:(DE-H253)PIP1084569$$aParaskaki, G.$$b4 000614238 7001_ $$0P:(DE-H253)PIP1015071$$aSchaper, L.$$b5 000614238 7001_ $$0P:(DE-H253)PIP1001613$$aSchreiber, Siegfried$$b6 000614238 7001_ $$0P:(DE-H253)PIP1003368$$aVogt, Mathias$$b7 000614238 7001_ $$0P:(DE-H253)PIP1006317$$aZemella, Johann$$b8 000614238 7001_ $$0P:(DE-HGF)0$$aAmstutz, Philipp$$b9 000614238 7001_ $$0P:(DE-H253)PIP1089789$$aAsatrian, Margarit$$b10 000614238 7001_ $$0P:(DE-H253)PIP1032393$$aHillert, Wolfgang$$b11 000614238 7001_ $$0P:(DE-H253)PIP1023734$$aPannek, F.$$b12 000614238 7001_ $$0P:(DE-H253)PIP1094107$$aSamoilenko, D.$$b13 000614238 7001_ $$0P:(DE-H253)PIP1106238$$aWenzel, H.$$b14 000614238 8564_ $$uhttps://fel2024.org/ 000614238 8564_ $$uhttps://bib-pubdb1.desy.de/record/614238/files/HTML-Approval_of_scientific_publication.html 000614238 8564_ $$uhttps://bib-pubdb1.desy.de/record/614238/files/PDF-Approval_of_scientific_publication.pdf 000614238 8564_ $$uhttps://bib-pubdb1.desy.de/record/614238/files/Finalized%20by%20editors.pdf$$yRestricted 000614238 8564_ $$uhttps://bib-pubdb1.desy.de/record/614238/files/TUP129-TUB.pdf$$yRestricted 000614238 8564_ $$uhttps://bib-pubdb1.desy.de/record/614238/files/Finalized%20by%20editors.pdf?subformat=pdfa$$xpdfa$$yRestricted 000614238 8564_ $$uhttps://bib-pubdb1.desy.de/record/614238/files/TUP129-TUB.pdf?subformat=pdfa$$xpdfa$$yRestricted 000614238 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1032318$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000614238 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1008868$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1100127$$a MPY$$b2 000614238 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1024674$$aDeutsches Elektronen-Synchrotron$$b3$$kDESY 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1084569$$aExternal Institute$$b4$$kExtern 000614238 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1015071$$aDeutsches Elektronen-Synchrotron$$b5$$kDESY 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1015071$$aExternal Institute$$b5$$kExtern 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1001613$$aExternal Institute$$b6$$kExtern 000614238 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1003368$$aDeutsches Elektronen-Synchrotron$$b7$$kDESY 000614238 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1006317$$aDeutsches Elektronen-Synchrotron$$b8$$kDESY 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$a Technical University of Dortmund University$$b9 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1089789$$aExternal Institute$$b10$$kExtern 000614238 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1032393$$aCentre for Free-Electron Laser Science$$b11$$kCFEL 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1032393$$aExternal Institute$$b11$$kExtern 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1023734$$aExternal Institute$$b12$$kExtern 000614238 9101_ $$0I:(DE-588)1043621512$$6P:(DE-H253)PIP1023734$$aEuropean XFEL$$b12$$kXFEL.EU 000614238 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1094107$$aCentre for Free-Electron Laser Science$$b13$$kCFEL 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1094107$$aExternal Institute$$b13$$kExtern 000614238 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1106238$$aExternal Institute$$b14$$kExtern 000614238 9131_ $$0G:(DE-HGF)POF4-6G2$$1G:(DE-HGF)POF4-6G0$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lGroßgeräte: Materie$$vFLASH (DESY)$$x0 000614238 9131_ $$0G:(DE-HGF)POF4-621$$1G:(DE-HGF)POF4-620$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Technologie$$vAccelerator Research and Development$$x1 000614238 9201_ $$0I:(DE-H253)MPY-20120731$$kMPY$$lBeschleunigerphysik$$x0 000614238 9201_ $$0I:(DE-H253)MFL-20120731$$kMFL$$lMaschinen Koordination FLASH$$x1 000614238 9201_ $$0I:(DE-H253)FS-LA-20130416$$kFS-LA$$lLaser Forschung und Entwicklung$$x2 000614238 980__ $$acontrib 000614238 980__ $$aEDITORS 000614238 980__ $$aVDBINPRINT 000614238 980__ $$aI:(DE-H253)MPY-20120731 000614238 980__ $$aI:(DE-H253)MFL-20120731 000614238 980__ $$aI:(DE-H253)FS-LA-20130416 000614238 980__ $$aUNRESTRICTED
