Until October 2013, I worked as a CERN fellow on the electromagnets for the new linear accelerator Linac4. I was involved in magnet design for other CERN projects, namely the PS Booster Upgrade and ELENA, the new antiproton decelerator. In addition, I supported work for MedAustron.
CERN has recently built the Large Hadron Collider (LHC), a superconducting circular particle accelerator designed for colliding two beams of protons at 7 TeV energy. The LHC is housed in a 27 km circumference tunnel, about 100 m underground.
In order to improve LHC performance, CERN has launched a long-term program for the progressive replacement or upgrade of the chain of accelerators presently used as injectors for the LHC. The Linac4 project is the first element of this program.
Linac4 is a linear accelerator for negative Hydrogen ions (H‾), which will replace Linac2 as linear injector for the CERN accelerators. Its higher energy of 160 MeV - the actual beam energy from Linac2 is 50 MeV - will give increased beam intensity in the downstream machines. Linac4 is about 100 m long, normal conducting, and is housed in a tunnel about 12 m below ground on the CERN Meyrin site, while a surface building houses the Linac4 equipment.
ELENA (Extra Low ENergy Antiproton Ring) is a compact ring for cooling and further deceleration of 5.3 MeV antiprotons delivered by the CERN Antiproton Decelerator (AD) to 100 keV. The AD physics program is focused on trapping antiprotons in Penning traps where antihydrogen is formed after recombination with positrons. The ultimate physics goal is to perform spectroscopy on antihydrogen atoms at rest and to investigate the effect of the gravitational force on matter and antimatter.
