The installation of Linac4 has started in 2013 with the 3 MeV Front End, aiming at delivering a fully commissioned 160 MeV H^{−} beam by 2016. During summer 2013 the H^{−} ion source, a clone of the first prototype, and the Low Energy Beam Transport lines have been installed in the Linac4 tunnel followed shortly by the Radiofrequency Quadrupole accelerator (RFQ), operating at the RF frequency of 352.2 MHz and which accelerates the ion beam to the energy of 3 MeV.

RF Tuning of the LINAC4 RFQ

The construction of Linac4, the new 160 MeV CERN H^{−} injector, has started with the goal of improving the LHC injection chain with a new higher energy linac. The low energy front end of Linac4 is based on a 352 MHz, 3-m long Radiofrequency Quadrupole (RFQ) which accelerates the 70 mA, 45 keV H^{−} beam from the ion source to the energy of 3 MeV. [...]

Commissioning of the Linac4 RFQ at the 3 MeV test stand
/ Rossi, C (CERN) ; Arnaudon, L (CERN) ; Bellodi, G (CERN) ; Broere, J (CERN) ; Brunner, O (CERN) ; Lombardi, A M (CERN) ; Balula, J M (CERN) ; Yanez, P M (CERN) ; Noirjean, J (CERN) ; Pasquino, C (CERN) et al.
Linac4, the future 160 MeV Hˉ injector to the CERN Proton Synchrotron Booster, is presently under construction at CERN as a first step of the planned upgrade of the LHC injectors. The low energy section of LINAC4, consisting of an ion source, a 352.2 MHz Radio Frequency Quadrupole (RFQ) and a chopper line is being commissioned in a dedicated test stand before installation in its final position in the tunnel.

Assembly and RF Tuning of the Linac4 RFQ at CERN

The fabrication of Linac4 is progressing at CERN with the goal of making a 160 MeV H- beam available to the LHC injection chain as from 2015. In the Linac4 the first stage of beam acceleration, after its extraction from the ion source, is provided by a Radiofrequency Quadrupole accelerator (RFQ), operating at the RF frequency of 352.2 MHz and which accelerates the ion beam to the energy of 3 MeV.

The RF Design of the Linac4 RFQ
/ Piquet, Olivier (Saclay) ; Delferriere, Olivier ; Desmons, Michel (Saclay) ; France, Alain (Saclay) ; Lombardi, Alessandra (CERN) ; Rossi, Carlo (CERN) ; Vretenar, Maurizio (CERN)
In the Linac 4 and the SPL, a 3 MeV RFQ is required to accelerate the Hbeam from the ion source to the DTL input energy. While the 6-meter long IPHI RFQ was initially chosen for this application, a CERN study suggested that a dedicated, shorter 3-meter RFQ might present several advantages [...]

Testing of super conducting low-beta 704 Mhz cavities at 50 Hz pulse repetition rate in view of SPL- first results
/ Höfle, W (CERN) ; Hernandez Flano, M (CERN) ; Lollierou, J (CERN) ; Valuch, D (CERN) ; Chel, S (Saclay) ; Devanz, G (Saclay) ; Desmons, M (Saclay) ; Piquet, O (Saclay) ; Paparella, R (INFN, Milan ; LASA, Segrate) ; Pierini, P (INFN, Milan ; LASA, Segrate)
In the framework of the preparatory phase for the luminosity upgrade of the LHC (SLHC-PP ) it is foreseen to characterize two superconducting RF cavities and demonstrate compliance of the required SPL field stability in amplitude and phase using a prototype LLRF system. We report on the preparation for testing of two superconducting low-beta cavities at 50 Hz pulse repetition rate including the setting-up of the low level RF control system to evaluate the performance of the piezo-tuning system and cavity field stability in amplitude and phase.
