However, a fundamental difference between plasma-based and conventional accelerators/focusing devices is that in the former the beams propagate through matter rather than a vacuum. This invariably leads to interactions such as Coulomb scattering between the beam and plasma particles, which in turn likely leads to emittance growth. Whereas the beam sizes inside plasma accelerators are comparatively small, limiting the induced emittance growth, the situation in plasma lenses is quite different as the beam size must be larger in these devices than in the accelerators to allow collimation or focusing. In particular, in active plasma lenses beam sizes must be large to avoid driving a wake, which in turn increases the induced emittance growth from scattering. This is further exacerbated by the fact that using gases of heavier elements, which scatter more strongly than their lighter counterparts, is preferable as they produce linear focusing gradients. However, direct measurements of the induced emittance growth from Coulomb scattering have hitherto not been shown for beam and lens parameters relevant to plasma-based focusing devices. In this work, we show the measurements of emittance growth from scattering in neutral (i.e. un-ionized) argon, nitrogen, and hydrogen over a range of pressures. Results from a corresponding set of simulations in GEANT4 and Ocelot, which represent the experimental environment, are also outlined. 000485673 536__ $$0G:(DE-HGF)POF4-621$$a621 - Accelerator Research and Development (POF4-621)$$cPOF4-621$$fPOF IV$$x0 000485673 693__ $$0EXP:(DE-H253)FLASHForward-20150101$$1EXP:(DE-H253)FLASH-20150101$$5EXP:(DE-H253)FLASHForward-20150101$$aFLASH$$eFLASHForward$$x0 000485673 7001_ $$0P:(DE-H253)PIP1086724$$aBoulton, Lewis$$b1 000485673 7001_ $$0P:(DE-H253)PIP1084257$$aGarland, Matthew James$$b2 000485673 7001_ $$0P:(DE-H253)PIP1086874$$aLindstroem, Carl Andreas$$b3 000485673 7001_ $$0P:(DE-H253)PIP1094542$$aPena Asmus, Felipe Lars$$b4 000485673 7001_ $$0P:(DE-H253)PIP1023434$$aSchröder, Sarah$$b5 000485673 7001_ $$0P:(DE-H253)PIP1006306$$aWesch, Stephan$$b6 000485673 7001_ $$0P:(DE-H253)PIP1089935$$aWood, Jonathan Christopher$$b7 000485673 7001_ $$0P:(DE-H253)PIP1012785$$aOsterhoff, Jens$$b8 000485673 7001_ $$0P:(DE-H253)PIP1027904$$aD'Arcy, Richard$$b9 000485673 8564_ $$uhttps://indico.classe.cornell.edu/event/2108/contributions/2051/ 000485673 8564_ $$uhttps://bib-pubdb1.desy.de/record/485673/files/AAC_emittance_growth_scattering_v3.pdf$$yRestricted 000485673 8564_ $$uhttps://bib-pubdb1.desy.de/record/485673/files/AAC_emittance_growth_scattering_v3.pdf?subformat=pdfa$$xpdfa$$yRestricted 000485673 909CO $$ooai:bib-pubdb1.desy.de:485673$$pVDB 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1094593$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000485673 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1086724$$aExternal Institute$$b1$$kExtern 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1084257$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1086874$$aDeutsches Elektronen-Synchrotron$$b3$$kDESY 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1094542$$aDeutsches Elektronen-Synchrotron$$b4$$kDESY 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1023434$$aDeutsches Elektronen-Synchrotron$$b5$$kDESY 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1006306$$aDeutsches Elektronen-Synchrotron$$b6$$kDESY 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1089935$$aDeutsches Elektronen-Synchrotron$$b7$$kDESY 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1012785$$aDeutsches Elektronen-Synchrotron$$b8$$kDESY 000485673 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1027904$$aDeutsches Elektronen-Synchrotron$$b9$$kDESY 000485673 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$$bForschungsbereich Materie$$lMatter and Technologies$$vAccelerator Research and Development$$x0 000485673 9141_ $$y2022 000485673 9201_ $$0I:(DE-H253)HH_FH_FTX_AS-20210421$$kHH_FH_FTX_AS$$lFTX Fachgruppe AST$$x0 000485673 9201_ $$0I:(DE-H253)MPA-20200816$$kMPA$$lPlasma Accelerators$$x1 000485673 9201_ $$0I:(DE-H253)MPA2-20210408$$kMPA2$$lBeam-Driven Plasma Accelerators$$x2 000485673 980__ $$aconf 000485673 980__ $$aVDB 000485673 980__ $$aI:(DE-H253)HH_FH_FTX_AS-20210421 000485673 980__ $$aI:(DE-H253)MPA-20200816 000485673 980__ $$aI:(DE-H253)MPA2-20210408 000485673 980__ $$aUNRESTRICTED
