Thermally generated acoustic shock waves [1,2] that accompany breakdowns can be easily detected on the surface of the cavity using externally mounted sensors. Acoustic emission sensors [3] have been used at the TESLA Test Facility to find RF high voltage breakdown locations in the photocathode gun system. It is not known if the acoustic signal emitted from the source (cathode) of the arc is stronger than that emitted from its terminus. The start time and root mean square amplitude of the signal from each of several sensors can be used to locate and classify the breakdown event. We report here on the use of eight sensors mounted on the TTF RF gun [4] to locate its breakdown events during operation with a pulse length of 300$μ$s and a pulse amplitude up to 35 MeV/m. 000415335 536__ $$0G:(DE-HGF)POF3-899$$a899 - ohne Topic (POF3-899)$$cPOF3-899$$fPOF III$$x0 000415335 588__ $$aDataset connected to INSPIRE 000415335 650_7 $$2INSPIRE$$aelectron positron: linear collider 000415335 650_7 $$2INSPIRE$$alinear collider: proposed 000415335 650_7 $$2INSPIRE$$aelectron: particle source 000415335 650_7 $$2INSPIRE$$aRF system: particle source 000415335 650_7 $$2INSPIRE$$aphotoelectron 000415335 650_7 $$2INSPIRE$$aelectric field: upper limit 000415335 650_7 $$2INSPIRE$$aDESY TESLA Linac 000415335 693__ $$0EXP:(DE-H253)TESLA-Test-Facility-20150101$$5EXP:(DE-H253)TESLA-Test-Facility-20150101$$eTESLA-Test-Facility$$x0 000415335 7001_ $$0P:(DE-H253)PIP1013916$$aRoss, M.$$b1 000415335 8564_ $$uhttps://bib-pubdb1.desy.de/record/415335/files/tesla2001-35.pdf$$yOpenAccess 000415335 8564_ $$uhttps://bib-pubdb1.desy.de/record/415335/files/tesla2001-35.gif?subformat=icon$$xicon$$yOpenAccess 000415335 8564_ $$uhttps://bib-pubdb1.desy.de/record/415335/files/tesla2001-35.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000415335 8564_ $$uhttps://bib-pubdb1.desy.de/record/415335/files/tesla2001-35.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000415335 8564_ $$uhttps://bib-pubdb1.desy.de/record/415335/files/tesla2001-35.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000415335 8564_ $$uhttps://bib-pubdb1.desy.de/record/415335/files/tesla2001-35.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000415335 909CO $$ooai:bib-pubdb1.desy.de:415335$$popenaire$$pVDB$$popen_access$$pdnbdelivery$$pdriver 000415335 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1024703$$aExternes Institut$$b0$$kExtern 000415335 9101_ $$0I:(DE-HGF)0$$6P:(DE-H253)PIP1013916$$aExternes Institut$$b1$$kExtern 000415335 9131_ $$0G:(DE-HGF)POF3-899$$1G:(DE-HGF)POF3-890$$2G:(DE-HGF)POF3-800$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bProgrammungebundene Forschung$$lohne Programm$$vohne Topic$$x0 000415335 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000415335 9201_ $$0I:(DE-H253)MXL-20160301$$kMXL$$lKoordination des XFEL-Beschleunigers$$x0 000415335 9201_ $$0I:(DE-H253)SLAC-20170401$$kSLAC$$lStanford Linear Accelerator Center$$x1 000415335 9201_ $$0I:(DE-H253)HAS-User-20120731$$kDOOR ; HAS-User$$lDOOR-User$$x2 000415335 980__ $$aintrep 000415335 980__ $$aVDB 000415335 980__ $$aUNRESTRICTED 000415335 980__ $$abook 000415335 980__ $$aI:(DE-H253)MXL-20160301 000415335 980__ $$aI:(DE-H253)SLAC-20170401 000415335 980__ $$aI:(DE-H253)HAS-User-20120731 000415335 9801_ $$aFullTexts
