First demonstration of the use of crab cavities on hadron beams
/ Calaga, R (CERN) ; Alekou, A (Manchester U.) ; Antoniou, F (CERN) ; Appleby, R B (Manchester U.) ; Arnaudon, L (CERN) ; Artoos, K (CERN) ; Arduini, G (CERN) ; Baglin, V (CERN) ; Barriere, S (CERN) ; Bartosik, H (CERN) et al.
Many future particle colliders require beam crabbing to recover geometric luminosity loss from the nonzero crossing angle at the interaction point (IP). A first demonstration experiment of crabbing with hadron beams was successfully carried out with high energy protons. [...]

Lab.) ; Burt, Graeme (Lancaster U. ; Daresbury) ; Calaga, Rama (CERN) ; Capatina, Ofelia (CERN) ; Huque, Naeem (Jefferson Lab) ; Li, Zenghai (SLAC) ; McEwen, Anne (Jefferson Lab) ; Mitchell, James (Lancaster U.) ; Park, HyeKyoung (Jefferson Lab) et al.
Crab cavities are one of the several components included in the luminosity upgrade of the Large Hadron Collider (HL-LHC). The cavities have to provide a nominal deflecting kick of 3.4 MV per cavity while the cryogenic load per cavity stays below 5 W. [...]

Architectural Considerations for Recirculated and Energy-Recovered Hard XFEL Drivers
/ Douglas, David (Jefferson Lab) ; Angal-Kalinin, Deepa (Daresbury ; Cockcroft Inst. Accel. Sci. Tech.) ; Benson, Stephen (Jefferson Lab) ; Charles, Tessa (CERN) ; Powers, Tom (Jefferson Lab) ; Roblin, Yves (Jefferson Lab) ; Satogata, Todd (Jefferson Lab) ; Tennant, Chris (Jefferson Lab) ; Thompson, Neil (Daresbury ; Cockcroft Inst. Accel. Sci. Tech.) ; Wheelhouse, Alan (Daresbury ; Cockcroft Inst. Accel. Sci. Tech.) et al.
A confluence of events motivates discussion of design options for hard XFEL driver accelerators. Firstly, multiple superconducting radio-frequency (SRF) driven systems are now online (European XFEL), in construction (LCLS-II), or in design (MARIE); these provide increasing evidence of the transformational potential they offer for fundamental science with its concomitant benefits.
