For the high-luminosity upgrade of the Large Hadron Collider, active control of proton/ion beam halo will be essential for safe and reliable operation. Hollow Electron Lenses can provide such active control by enhancing the depletion of halo particles, and are now an integral part of the high luminosity LHC collimation system [...]

Electron beam dynamics simulation for electron lenses
/ Sadovich, Sergey (CERN) ; Rossi, Adriana (CERN) ; Stancari, Giulio (Fermilab)
A test stand is under construction at CERN to study high perveance electron guns, electron beam dynamics, and electron beam diagnostics for electron lenses. It will be used to test electron guns for the Hollow Electron Lenses under consideration for beam halo control for High Luminosity LHC (CERN), and for the Space Charge Compensation at SIS18 (GSI) in the frame of the EU funded ARIES project.

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). [...]

The Design, Construction and Operation of the Beam Instrumentation for the High Intensity and Energy Upgrade of ISOLDE at CERN
/ Andreazza, William (CERN) ; Bravin, Enrico (CERN) ; Cantero, Esteban (CERN) ; Carmona, José Miguel (AVS, Elgoibar) ; Galipienzo, Julio (AVS, Elgoibar) ; Noguera Crespo, Pedro (AVS, Elgoibar) ; Sadovich, Sergey (CERN) ; Sosa, Alejandro (CERN) ; Veness, Raymond (CERN)
The High Intensity and Energy (HIE) upgrade to the on-line isotope separation facility (ISOLDE) facility at CERN is currently in the process of being commissioned. The very tight space available between the superconducting acceleration cavities used and a challenging specification led to the design of a compact 'diagnostic box' with a number of insertable instruments on a common vacuum chamber.

The HIE-ISOLDE Linac (High Intensity and Energy) is a recent upgrade to the ISOLDE facility of CERN, increasing the maximum beam energy and providing means to explore more scientific opportunities. The main software tools required to set up the new superconducting post-accelerator and to characterise the beam provided to the experimental stations will be presented in this paper. [...]

After the first successful physics run with radioactive ion beams at HIE ISOLDE, in October 2015 [1], the staged deployment of the linac continued in 2016 by adding a second cryomodule and by refurbishing the first one. During the physics run with one cryomodule, the second cryomodule was being assembled. [...]
