Title Higher order modes in third harmonic cavities for XFEL/FLASH
Abstract We anal­yse the high­er order modes in the 3.9GHz bunch shap­ing cav­i­ties re­cent­ly in­stalled in the XFEL/FLASH fa­cil­i­ty at DESY. We re­port on re­cent ex­per­i­men­tal re­sults on the fre­quen­cy spec­trum, both beam and probe based. These are com­pared to those pre­dict­ed by fi­nite el­e­ment com­put­er codes, glob­alised scat­ter­ing ma­trix cal­cu­la­tions and a two-band cir­cuit model. This study is fo­cused on the dipole com­po­nent of the multi­band ex­pan­sion of the wake­field.
