RF Measurements and Tuning of the CERN 750 MHz ELISA-RFQ for Public Exhibition / Marchi, Mariangela (CERN ; U. Rome La Sapienza (main)) ; Grudiev, Alexej (CERN) ; Mathot, Serge (CERN) ; Pommerenke, Hermann (CERN)
Over the last few years, CERN has successfully designed, built, and commissioned the smallest RFQ to date, the one meter long PIXE-RFQ operating at 750 MHz. Its compactness offers a unique opportunity for education and public presentation of the accelerator community: A duplicate ma- chine called ELISA-RFQ (Experimental Linac for Surface Analysis) will be exhibited in the Science Gateway, CERN’s upcoming scientific education and outreach center.

Rostock)
Protons with an energy of few MeV are commonly used for Ion Beam Analysis of materials, in particular with the Proton Induced X-ray Emission technique (PIXE). Because of its non-damaging character, PIXE is used in a variety of fields, in particular for the diagnosis of cultural heritage artwork. [...]

Beam Dynamics and RF Design Studies for the New RFQ for CERN Linac4 Upgrade / Pommerenke, Hermann (CERN) ; Bellodi, Giulia (CERN) ; Grudiev, Alexej (CERN) ; Kumar, Sarvesh (CERN) ; Lombardi, Alessandra (CERN)
The 352 MHz Linac4-RFQ is the first rf accelerating structure of the CERN accelerator complex, accelerating an H-beam to 3 MeV. After successful commissioning in 2013, superficial vane damage has been observed in 2020. [...]

RF Design of Traveling-Wave Accelerating Structures for the FCC-ee Pre-injector Complex / Pommerenke, Hermann (CERN) ; Bettoni, Simona (PSI, Villigen) ; Craievich, Paolo (PSI, Villigen) ; Grudiev, Alexej (CERN) ; Latina, Andrea (CERN) ; Raguin, Jean-Yves (PSI, Villigen) ; Schaer, Mattia (PSI, Villigen)
The linacs of the FCC-ee (Future Circular Electron-Positron Collider) injector complex will provide the drive beam for positron production and accelerate nominal electron and positron beams up to 6 GeV. Several linacs comprise different traveling-wave (TW) accelerating structures fulfilling the beam dynamics and rf constraints. [...]

The FCCee Pre-Injector Complex / Craievich, Paolo (PSI, Villigen) ; Alharthi, Fahad (IJCLab, Orsay) ; Auchmann, Bernhard (PSI, Villigen) ; Bartmann, Wolfgang (CERN) ; Benedikt, Michael (CERN) ; Besana, Maria Ilaria (CERN) ; Bettoni, Simona (PSI, Villigen) ; Braun, Hans-Heinrich (PSI, Villigen) ; Calviani, Marco (CERN) ; Chaikovska, Iryna (IJCLab, Orsay) et al.
The international FCC study group published in 2019 a Conceptual Design Report for an electron-positron collider with a centre-of-mass energy from 90 to 365 GeV with a beam currents of up to 1.4 A per beam. The high beam current of this collider create challenging requirements on the injection chain and all aspects of the linac need to be carefully reconsidered and revisited, including the injection time structure.

High-frequency compact RFQs for medical and industrial applications / Vretenar, Maurizio (CERN) ; Dimov, Veliko (CERN) ; Garlaschè, Marco (CERN) ; Grudiev, Alexej (CERN) ; Koubek, Benjamin (CERN) ; Lombardi, Alessandra (CERN) ; Mathot, Serge (CERN) ; Mazur, David (CERN) ; Montesinos, Eric (CERN) ; Timmins, Marc (CERN)
CERN has completed the construction of a 750 MHz RFQ reaching 5 MeV proton energy in a length of only 2 meters, to be used as injector for a compact proton therapy linac. Beyond proton therapy, this compact and lightweight design can be used for several applications, ranging from the production of radioisotopes in hospitals to ion beam analysis of industrial components or of artworks.

Beam Dynamics in a High Frequency RFQ / Lombardi, Alessandra (CERN) ; Dimov, Veliko (CERN) ; Garlaschè, Marco (CERN) ; Grudiev, Alexej (CERN) ; Mathot, Serge (CERN) ; Montesinos, Eric (CERN) ; Myers, Stephen (CERN) ; Timmins, Marc (CERN) ; Vretenar, Maurizio (CERN)
CERN is constructing a 750 MHz Radio Frequency Quadrupole (RFQ) which can accelerate a proton beam to 5 MeV in a length of 2 m. The beam dynamics strategic parameters have been chosen to make this RFQ a good candidate for the injector of a medical facility operating at frequency of 3 GHz. [...]

rf measurements and tuning of the 1-m-long 750 MHz radio-frequency quadrupole for artwork analysis / Pommerenke, Hermann W. (CERN ; U. Rostock) ; van Rienen, Ursula (U. Rostock) ; Grudiev, Alexej (CERN)
The 750 MHz PIXE-RFQ (radio-frequency quadrupole), developed and built at CERN, provides 2 MeV protons over a length of one meter for proton-induced X-ray emission analysis (PIXE) of cultural heritage artwork. In this paper, we report low-power rf measurements and tuning of the PIXE-RFQ, which have been completed mid-2020. [...]
