Simulation of beam loading compensation with RF-Track
/ Olivares Herrador, Javier (CERN ; Valencia U., IFIC) ; Latina, Andrea (CERN) ; Gimeno-Martinez, Benito (Valencia U., IFIC) ; Esperante Pereira, Daniel (Valencia U., IFIC) ; Fuster-Martinez, Nuria (Valencia U., IFIC) ; Zhao, Yongke (CERN)
The beam loading effect results in a gradient reduction of accelerating structures due to the excitation of the fundamental mode when the beam travels through the cavity. A recent implementation of this process in the tracking code RF-Track allows the simulation of realistic scenarios, thus revealing the impact of this phenomenon in start-to-end accelerator designs.

Beam Loading Simulation for Relativistic and Ultrarelativistic Beams in the Tracking Code RF-Track
/ Olivares Herrador, Javier (CERN ; Valencia U., IFIC) ; Esperante Pereira, Daniel (Valencia U., IFIC) ; Fuster, Nuria (Valencia U., IFIC) ; Gimeno, Benito (Valencia U., IFIC) ; Latina, Andrea (CERN)
Medical and industrial electron linacs can benefit from the X-band accelerating technology developed for the Compact Linear Collider (CLIC) at CERN. However, when high-intensity beams are injected in such high-gradient structures (>35 MV/m), the beam loading effect must be considered by design since this beam-cavity interaction can result in a considerable gradient reduction with respect to the unloaded case. [...]

CompactLight (XLS) is an International Collaboration of 24 partners and 5 third parties, funded by the European Union through the Horizon 2020 Research and Innovation Programme. The main goal of the project, which started in January 2018 with a duration of 36 months, is the design of an hard X-ray FEL facility beyond today’s state of the art, using the latest concepts for bright electron photo-injectors, high-gradient accelerating structures, and innovative short-period undulators.

High-gradient testing of an $S$-band, normal-conducting low phase velocity accelerating structure
/ Vnuchenko, A (Valencia U., IFIC) ; Esperante Pereira, D (Valencia U., IFIC) ; Gimeno Martinez, B (Valencia U., IFIC) ; Benedetti, S (CERN) ; Catalan Lasheras, N (CERN) ; Garlasch, M (CERN) ; Grudiev, A (CERN) ; McMonagle, G (CERN) ; Pitman, S (CERN) ; Syratchev, I (CERN) et al.
A novel high-gradient accelerating structure with low phase velocity, v/c=0.38, has been designed, manufactured and high-power tested. The structure was designed and built using the methodology and technology developed for CLIC 100 MV/m high-gradient accelerating structures, which have speed of light phase velocity, but adapts them to a structure for nonrelativistic particles.

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.
