H− extraction systems for CERN’s Linac4 H− ion source

2018

Abstract Linac4 is a 160 MeV linear H −  accelerator at CERN. It is an essential part of the beam luminosity upgrade of the Large Hadron Collider (LHC) and will be the primary injector into the chain of circular accelerators. It aims at increasing the beam brightness by a factor of 2, when compared to the currently used 50 MeV linear proton accelerator, Linac2. Linac4’s ion source is a cesiated RF-plasma H −  ion source. Several beam extraction systems were designed for H −  beams of 45 keV energy, 50 mA intensity and an electron to H −  ratio smaller than 5. The goal was to extract a beam with an rms-emittance of 0 . 25 π  mm mrad. One of the main challenges in designing an H −  extraction…
