چکیده انگلیسی
In the 8Â GeV compact X-ray FEL “SACLA,” a single bunch of electrons is compressed to a duration of approximately 30Â fs to yield a peak current of 3Â kA, which creates brilliant self-amplified spontaneous emission. To measure the longitudinal profile of an ultrashort electron bunch and verify the compression, we developed a high-gradient C-band RF deflecting structure 1.8Â m long and periodically loaded with racetrack-shaped irises. The irises generated a high deflection gradient for the vertically deflecting HEM11-5Ï/6 dipole mode and suppressed rotation of the deflection plane. The two structures were fabricated and generated a stable total deflecting voltage exceeding 60Â MV and revealed the longitudinal electron-bunch profile with an effective time resolution of approximately 10Â fs.
