In December 2020 the newly commissioned LINAC4 started delivering beam for the CERN
proton accelerator chain, replacing the old LINAC2. LINAC4 is a 352 MHz normal …

CERN's Super Proton Synchrotron (SPS) accelerates protons to 4 5 0 GeV/c and transfers
them into the Large Hadron Collider (LHC). It is currently one of the limiting factors in …

New projects being implemented or planned at CERN, such as the LHC Injectors Upgrade
(LIU), the High-Luminosity LHC (HL-LHC) or the Future Circular Collider (FCC), motivate the …

At the end of the Large Hadron Collider's Run 2, CERN's Proton Injector Linac 2,
commissioned in 1978, delivered its final beam in December 2018. For Run 3, from March …

High-energy linear particle accelerators enable exploration of the microscopic structure of
pharmaceuticals, solar cells, fuel cells, high-temperature superconductors, and the universe …

Abstract The CERN Linac4 Low Level RF (LLRF) uses a Linear Quadratic Gaussian
regulator and an Adaptive Feed Forward to stabilize the accelerating field in the cavities in …

In Particle Accelerators, the Low-Level RF (LLRF) is the control system of the RF, and in the
end, of the purpose of the machine, that is the energy transfer and acceleration of particles. It …

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 …
