Development of a Field Emission Electron Gun for Low Energy Electron Cooling / Tranquille, Gerard (CERN) ; Cenede, Jean (CERN) ; Galante, Bruno (CERN ; PSI, Villigen) ; Welker, Elisabeth-Sena (CERN ; Vienna, Tech. U.)
The use of carbon nanotubes (CNT) as a cold electron source for a low energy electron cooler has been studied in detail. To fully characterise different CNT arrays (conditioning process, emitted current, lifetime) and to investigate the optimum electrical configuration of the source to be used in an electron gun, a cold cathode test bench (CCTB) has been set up. [...]

An electron beam test stand has been designed and constructed at CERN as part of the High Luminosity LHC (HL-LHC) project, in collaboration with the ARIES project, to test components related to the Hollow Electron Lens (HL-LHC) and the GSI Space Charge Compensation Electron Lens (ARIES). This comprehensive test facility incorporates normal conducting solenoid magnets, including horizontal and vertical correctors, which generate fields of fractional Tesla magnitude. [...]

DC and pulsed electron beam test facility at CERN / Rossi, Adriana (CERN) ; Kolehmainen, Antti (CERN) ; Churchman, Ashley (CERN) ; Perini, Diego (CERN) ; Guillot-Vignot, Franck (CERN) ; Wenander, Fredrik (CERN) ; Zhang, Hao (Liverpool U.) ; Cenede, Jean (CERN) ; Wendt, Manfred (CERN) ; Toscan du Plantier, Maxime (CERN) et al.
An electron beam test stand was designed and constructed at CERN, under the umbrella of the Hi-Lumi project, to tests components for the Hollow Electron Lens (HEL), and in collaboration with the ARIES project for testing the Space Charge Compensation gun. The test facility features normal conductive magnets providing solenoid fields of the order of fractions of Tesla, beam diagnostics including screens (YAG, Cromox and OTR) for the full electron beam characterisation, a Faraday Cup collector to measure the total electron current, and a high voltage power supply up to 40 kV (with the possibility of biasing both gun and collector).

Specifications for a new electron cooler of the antiproton decelerator at CERN / Gamba, Davide (CERN) ; Rossi, Adriana (CERN) ; Russo, Giulia (CERN) ; Kruyt, Peter (CERN ; Frankfurt U.)
After more than 40 years of operation in different machines, the Antiproton Decelerator (AD) electron cooler (e-cooler) is expected to be replaced by a new one designed at CERN. This new design is primarily driven by the necessity to ensure the reliable operation of the CERN antimatter facility for the next decade and beyond. [...]

Access to Effective Cancer Care in Low- Middle Income Countries Requires Sophisticated Linear Accelerator Based Radiotherapy / Dosanjh, Manjit (CERN)
There are substantial and growing gaps in cancer care for millions of people in Low- Middle- Income countries (LMICs) and for geographically remote settings in High-income countries (HICs), often indigenous populations. Assessing the cancer care shortfall led to understanding the essential gap, that of a radiation therapy machine that can reliably and effectively provide the appropriate first-rate cancer treatments within the challenging environments.
