/ Fang, Wencheng ; Gu, Qiang ; Zhang, Meng ; Zhao, Zhentang ; Aksoy, Avni ; Yavaş, Omer ; Angal-Kalinin, Deepa ; Clarke, James ; Bocchetta, Carlo ; Wawrzyniak, Adriana et al.
One compact hard X-ray FEL facility is being planned at SINAP, and X-band high gradient accelerating structure is the most competetive scheme for this plan. X-band accelerating structure is designed to switch between 60MV/m and 80MV/m, and carries out 6GeV and 8GeV by 130 meters linac respectively. [...]

Study on the design of the X-band waveguide-damped structure
/ Huang, Xiaoxia (Shanghai SSRF) ; Fang, Wencheng (Shanghai SSRF ; SINAP, Shanghai) ; Grudiev, Alexej (CERN) ; Zhao, Zhentang (Shanghai SSRF ; SINAP, Shanghai)
The design of waveguide-damped structure is optimized to reduce the magnitudes of surface electromagnetic fields and strongly suppress long-range transverse wakefields of the 380 GeV Compact Linear Collider facility currently under study. The optimization is mainly discussed with the elliptical shape of the iris, the wall shape of the damping waveguides, the position of the high-order-mode damping loads and the widths of the waveguide openings of the entire sequence of damping waveguides..

X-band Technology for FEL Sources
/ D'Auria, Gerardo ; Di Mitri, Simone ; Serpico, Claudio ; Adli, Erik ; Aksoy, Avni ; Yavaş, Omer ; Angal-Kalinin, Deepa ; Clarke, James ; Bocchetta, Carlo ; Wawrzyniak, Adriana et al.
As is widely recognized, fourth generation Light Sources are based on FELs driven by Linacs. Soft and hard X-ray FEL facilities are presently operational at several laboratories, SLAC (LCLS), Spring-8 (SACLA), Elettra-Sincrotrone Trieste (FERMI), DESY (FLASH), or are in the construction phase, PSI (SwissFEL), PAL (PAL-XFEL), DESY (European X-FEL), SLAC (LCLS II), or are newly proposed in many laboratories.

The X-Band FEL Collaboration
/ Pfingstner, Juergen (Oslo U.) ; Adli, Erik (Oslo U.) ; Aksoy, Avni (Ankara U., Inst. Accel. Technol.) ; Angal-Kalinin, Deepa (Daresbury) ; Bocchetta, Carlo (Jagiellonian U. (main)) ; Boland, Mark (ASP, Melbourne) ; Burt, Graeme (Lancaster U.) ; Catalán Lasheras, Nuria (CERN) ; Charitonidis, Anastasios (Natl. Tech. U., Athens) ; Charles, Tessa (ASP, Melbourne) et al.
The X-band FEL collaboration is currently designing an X-ray free-electron laser based on X-band acceleration technology. Due to the higher accelerating gradients achievable with X-band technology, a X-band normal conducting linac can be shorter and therefore potentially cost efficient than what is achievable with lower frequency structures.

H2020 CompactLight Project aims at designing the next generation of compact hard X-Rays Free-Electron Lasers, relying on very high accelerating gradients and on novel undulator concepts. CompactLight intends to design a compact Hard X-ray FEL facility based on very high-gradient acceleration in the X band of frequencies, on a very bright photo injector, and on short-period/superconductive undulators to enable smaller electron beam energy.

Beam-Based Measurements of Long Range Transverse Wakefields in CLIC Main Linac Accelerating Structure
/ Zha, Hao (CERN) ; Adli, Erik (Oslo U.) ; De Michele, Giovanni (EPFL-ISIC, Lausanne ; PSI, Villigen) ; Grudiev, Alexej (CERN) ; Latina, Andrea (CERN) ; Lipkowitz, Nate (SLAC) ; Schulte, Daniel (CERN) ; Solodko, Anastasiya (CERN) ; Wuensch, Walter (CERN) ; Yocky, Gerald (SLAC)
The baseline design of CLIC (Compact Linear Collider) uses X-band accelerating structures in the main linac. Every accelerating structure cell has four waveguides, terminated with individual RF loads, to damp the unwanted long-range transverse wakefields, in order to maintain beam stability in multi-bunch operation.
