Beam measurement of the high frequency impedance sources with long bunches in the CERN Super Proton Synchrotron / Lasheen, A (CERN ; Orsay) ; Argyropoulos, T (CERN) ; Bohl, T (CERN) ; Esteban Müller, J  F (CERN) ; Timko, H (CERN) ; Shaposhnikova, E (CERN)
Microwave instability in the Super Proton Synchrotron (SPS) at CERN is one of the main limitations to reach the requirements for the High Luminosity-LHC project (increased beam intensity by a factor 2). To identify the impedance source responsible of the instability, beam measurements were carried out to probe the SPS impedance. [...]

Slow Extraction of Charged Ion Pulses from the REXEBIS / Bidault, Niels (CERN) ; Rodriguez, Jose Alberto (CERN) ; Lozano, Miguel (CERN) ; Sadovich, Sergey (CERN)
The Isotope mass Separator On-Line DEvice (ISOLDE) facility located at CERN, produces and transports Radioactive Ion Beams (RIBs) at low or high energy through the REX/HIE-ISOLDE linear accelerator, for nuclear physics, astrophysics, solid-state physics and applied-physics purposes. Increasing the charge state of the ions is a prerequisite for efficient acceleration and is accomplished by an Electron Beam Ion Source (REXEBIS). [...]
