THz pulses are generated at a radiation wavelength of 100µm within a 3.5 m long, strongly focusing planar LCLS-I undulator. High gain is achieved by driving the FEL with high brightness beams from the PITZ photoinjector at 17MeV and a bunch charge of up to several nC. In addition to the mechanisms of self-amplified spontaneous emission (SASE), seeding of the THz-FEL by electron bunch modulation at the photocathode is also being investigated. The experimental results, including the gain curves, spectral properties and transverse distribution of the THz-FEL radiation, are presented in comparison with theoretical predictions and numerical simulations. 000627268 536__ $$0G:(DE-HGF)POF4-621$$a621 - Accelerator Research and Development (POF4-621)$$cPOF4-621$$fPOF IV$$x0 000627268 693__ $$0EXP:(DE-H253)PITZ-20150101$$5EXP:(DE-H253)PITZ-20150101$$ePhoto Injector Test Facility$$x0 000627268 8564_ $$uhttps://bib-pubdb1.desy.de/record/627268/files/THzoverview.pdf$$yRestricted 000627268 8564_ $$uhttps://bib-pubdb1.desy.de/record/627268/files/THzoverview.pdf?subformat=pdfa$$xpdfa$$yRestricted 000627268 909CO $$ooai:bib-pubdb1.desy.de:627268$$pVDB 000627268 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1086967$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000627268 9131_ $$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$$x0 000627268 9141_ $$y2025 000627268 9201_ $$0I:(DE-H253)Z_PITZ-20210408$$kZ_PITZ$$lTechnologie$$x0 000627268 980__ $$areview 000627268 980__ $$aVDB 000627268 980__ $$aI:(DE-H253)Z_PITZ-20210408 000627268 980__ $$aUNRESTRICTED
