Time-resolved measurements of both longitudinal and transverse wakefields of the device are presented and compared with simulations. We demonstrate flexible control of the LCLS FEL bandwidth and present novel uses of the device in addition to energy chirp control. PB - JACoW CP - Geneva, Switzerland ER -
