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.

TULIP (TUrning LInac for Protontherapy) is a novel compact accelerator system for protontherapy mounted on a rotating gantry (Amaldi et al., 2013, 2010, 2009). Its high-energy Linac has the unique property of being able to modulate the beam energy from one pulse to the next, in only a couple of milliseconds. [...]

New Trends in Proton and Carbon Therapy Linacs
/ Benedetti, Stefano (CERN)
In the last years, many developments have contributed to make feasible an all linac solution for proton and carbon ion therapy, with typical output energies of about 200 MeV and 400 MeV/u, respectively. The efficient beam matching of the source to the high-energy linacs, operating at 3 GHz, represents one of the major challenges. [...]

Melbourne (main)) ; McMonagle, Gerard (CERN) et al.
The high-gradient performance of an accelerating structure prototype for a medical proton linac is presented. The structure was designed and built using technology developed by the CLIC collaboration and the target application is the TULIP (Turning Linac for Proton therapy) proposal developed by the TERA foundation.

Simulation and Measurement Campaigns for Characterization and Performance Improvement of the CERN Heavy Ion Linac3
/ Bellodi, Giulia (CERN) ; Benedetti, Stefano (CERN) ; Küchler, Detlef (CERN) ; Toivanen, Ville (GANIL) ; Wenander, Fredrik (CERN)
In the framework of the LHC Injector Upgrade programme (LIU), several activities have been carried out to improve the GTS-LHC ion source and Linac3 performance (Linac3 providing the charged heavy ion beams for CERN exper-iments). A restudy of the beam dynamics and transport through the linac was initiated, through a campaign of systematic machine measurements and parallel beam simulations, generalising techniques developed for beam characterization during Linac4 commissioning.

Redesign of CERN LINAC3 RFQ for Lead 29+
/ Benedetti, Stefano (CERN) ; Bellodi, Giulia (CERN) ; Lallement, Jean-Baptiste (CERN) ; Lombardi, Alessandra (CERN)
CERN Linac3 is at the heart of the CERN Heavy Ion Facility, providing 4.2 MeV/u ion beams to the Low Energy Ion Ring (LEIR). It mostly accelerates 208Pb29+, though in recent years runs were performed with 40Ar11+ and 129Xe22+, in view of the raising interest of the physics community towards lighter ions experiments. [...]

The 2017 Xe run at CERN Linac3: measurements and beam dynamics simulations
/ Benedetti, Stefano (CERN) ; Bellodi, Giulia (CERN) ; Kuchler, Detlef (CERN) ; Lombardi, Alessandra (CERN) ; Wenander, Fredrik John Carl (CERN) ; Toivanen, Ville Aleksi (GANIL)
At CERN, large hadron collider heavy ion and super proton synchrotron fixed target experiments are performed thanks to the Heavy-ion Facility, composed of different accelerators. The starting point is Linac3, which delivers 4.2 MeV/u ion beams to the low energy ion ring. [...]

Design of a 750 MHz IH structure for medical applications
/ Benedetti, Stefano (CERN ; Ecole Polytechnique, Lausanne) ; Grudiev, Alexej (CERN) ; Latina, Andrea (CERN)
Low velocity particles are critical in every hadron accelerator chain. While RFQs nicely cover the first MeV/u range, providing both acceleration and bunching, energies higher than few MeV/u require different structures, depending on the specific application. [...]

Fabrication and testing of a novel S-Band backward travelling wave accelerating structure for proton therapy linacs
/ Benedetti, Stefano (CERN ; Ecole Polytechnique, Lausanne) ; Argyropoulos, Theodoros (CERN) ; Blanch Gutiérrez, Cesar (CERN) ; Catalán Lasheras, Nuria (CERN) ; Degiovanni, Alberto (CERN) ; Esperante Pereira, Daniel (Valencia U., IFIC ; CERN) ; Garlaschè, Marco (CERN) ; Giner Navarro, Jorge (CERN) ; Grudiev, Alexej (CERN) ; McMonagle, Gerard (CERN) et al.
Compact and more affordable, facilities for proton therapy are now entering the market of commercial medical accelerators. At CERN, a joint collaboration between CLIC and TERA Foundation led to the design, fabrication and testing of a high gradient accelerating structure prototype, capable of halving the length of state-of-art light ion therapy linacs.
