A rapid method for prediction of the non-resonant ultra-fast multipactor regime in high gradient RF accelerating structures / González-Iglesias, Daniel (Valencia U., IFIC) ; Gimeno, Benito (Valencia U., IFIC) ; Esperante, Daniel (Valencia U., IFIC) ; Martinez-Reviriego, Pablo (Valencia U., IFIC) ; Martín-Luna, Pablo (Valencia U., IFIC) ; Pedraza, Laura Karina (Valencia U., IFIC) ; Fernández, Juan Carlos (Valencia U., IFIC) ; Fuster-Martínez, Nuria (Valencia U., IFIC) ; Martínez, Eduardo (Valencia U., IFIC) ; Boronat, Marçà (Valencia U., IFIC) et al.
The purpose of this work is to present an analytical method that allows to estimate in an approximate and fast way the presence of the non-resonant and ultra-fast multipactor effect in RF accelerating structures in the presence of high gradient electromagnetic fields. This single-surface multipactor regime, which has been little studied in the scientific literature, is characterised by appearing only under conditions of very strong RF electric fields (of the order of tens or hundreds of MV/m), where it is predominant over other types of single- or dual-surface resonance described in classical multipactor theory.

Non-resonant ultra-fast multipactor regime in dielectric-assist accelerating structures / González-Iglesias, Daniel (Valencia U., IFIC) ; Gimeno, Benito (Valencia U., IFIC) ; Esperante, Daniel (Valencia U., IFIC) ; Martinez-Reviriego, Pablo (Valencia U., IFIC) ; Martín-Luna, Pablo (Valencia U., IFIC) ; Fuster-Martínez, Nuria (Valencia U., IFIC) ; Blanch, César (Valencia U., IFIC) ; Martínez, Eduardo (Valencia U., IFIC) ; Menendez, Abraham (Valencia U., IFIC) ; Fuster, Juan (Valencia U., IFIC) et al.
The objective of this work is the evaluation of the risk of suffering a multipactor discharge in an S-band dielectric-assist accelerating (DAA) structure for a compact low-energy linear particle accelerator dedicated to hadrontherapy treatments. A DAA structure consists of ultra-low loss dielectric ciylinders and disks with irises which are periodically arranged in a metallic enclosure, with the advantage of having an extremely high quality factor and very high shunt impedance at room temperature, and it is therefore proposed as a potential alternative to conventional disk-loaded copper structures.

Dielectric Assist Accelerating Structures for Compact Linear Accelerators of Low Energy Particles in Hadrontherapy Treatments / Martinez-Reviriego, Pablo (Valencia U., IFIC) ; Esperante, Daniel (Valencia U., IFIC ; Valencia U.) ; Grudiev, Alexej (CERN) ; Gimeno, Benito (Valencia U., IFIC) ; Blanch, Cesar (Valencia U., IFIC) ; Gonzalez-Iglesias, Daniel (Valencia U., IFIC) ; Fuster-Martınez, Nuria (Valencia U., IFIC) ; Martín-Luna, Pablo (Valencia U., IFIC) ; Martínez, Eduardo (Valencia U., IFIC) ; Menendez, Abraham (Valencia U., IFIC) et al.
Dielectric Assist Accelerating (DAA) structures based on ultralow-loss ceramic are being studied as an alternative to conventional disk-loaded copper cavities. This accelerating structure consists of dielectric disks with irises arranged periodically in metallic structures working under the TM$_{02}$-$\pi$ mode. [...]

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.

An S-band High-Gradient (HG) Radio Frequency (RF) laboratory is under construction and commissioning at IFIC. The purpose of the laboratory is to perform investigations of high-gradient phenomena and to develop normal-conducting RF technology, with special focus on RF systems for hadron-therapy. [...]
