One of the key reasons for this success is the `self-gating' pulse effect, whereby the X-ray laser pulses do not need to outrun all radiation damage processes. Instead, X-ray-induced damage terminates the Bragg diffraction prior to the pulse completing its passage through the sample, as if the Bragg diffraction were generated by a shorter pulse of equal intensity. As a result, serial femtosecond crystallography does not need to be performed with pulses as short as 5–10 fs, but can succeed for pulses 50–100 fs in duration. It is shown here that a similar gating effect applies to single-molecule diffraction with respect to spatially uncorrelated damage processes like ionization and ion diffusion. The effect is clearly seen in calculations of the diffraction contrast, by calculating the diffraction of the average structure separately to the diffraction from statistical fluctuations of the structure due to damage (`damage noise'). The results suggest that sub-nanometre single-molecule imaging with 30–50 fs pulses, like those produced at currently operating facilities, should not yet be ruled out. The theory presented opens up new experimental avenues to measure the impact of damage on single-particle diffraction, which is needed to test damage models and to identify optimal imaging conditions. 000293484 536__ $$0G:(DE-HGF)POF3-6215$$a6215 - Soft Matter, Health and Life Sciences (POF3-621)$$cPOF3-621$$fPOF III$$x0 000293484 588__ $$aDataset connected to CrossRef 000293484 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000293484 7001_ $$aCorso, Justine K.$$b1 000293484 7001_ $$0P:(DE-H253)PIP1011740$$aCaleman, Carl$$b2 000293484 7001_ $$aTimneanu, Nicusor$$b3 000293484 7001_ $$aQuiney, Harry M.$$b4 000293484 773__ $$0PERI:(DE-600)2754953-7$$a10.1107/S2052252515016887$$gVol. 2, no. 6, p. 661 - 674$$n6$$p661 - 674$$tIUCrJ$$v2$$x2052-2525$$y2015 000293484 8564_ $$uhttps://bib-pubdb1.desy.de/record/293484/files/it5006.pdf$$yOpenAccess 000293484 8564_ $$uhttps://bib-pubdb1.desy.de/record/293484/files/it5006.gif?subformat=icon$$xicon$$yOpenAccess 000293484 8564_ $$uhttps://bib-pubdb1.desy.de/record/293484/files/it5006.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000293484 8564_ $$uhttps://bib-pubdb1.desy.de/record/293484/files/it5006.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000293484 8564_ $$uhttps://bib-pubdb1.desy.de/record/293484/files/it5006.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000293484 909CO $$ooai:bib-pubdb1.desy.de:293484$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000293484 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1011740$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000293484 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1011740$$aCentre for Free-Electron Laser Science$$b2$$kCFEL 000293484 9131_ $$0G:(DE-HGF)POF3-621$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6215$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vIn-house research on the structure, dynamics and function of matter$$x0 000293484 9141_ $$y2015 000293484 915__ $$0LIC:(DE-HGF)CCBY2$$2HGFVOC$$aCreative Commons Attribution CC BY 2.0 000293484 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000293484 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000293484 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000293484 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000293484 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000293484 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000293484 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000293484 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000293484 9201_ $$0I:(DE-H253)FS-CFEL-1-20120731$$kFS-CFEL-1$$lCFEL-Coherent X-Ray Imaging$$x0 000293484 980__ $$ajournal 000293484 980__ $$aVDB 000293484 980__ $$aUNRESTRICTED 000293484 980__ $$aI:(DE-H253)FS-CFEL-1-20120731 000293484 9801_ $$aUNRESTRICTED 000293484 9801_ $$aFullTexts
