A New Electron Cooler for the CERN Antiproton Decelerator (AD)

The current electron cooler at the Antiproton Decelerator (AD) at CERN was built in the second half of the 1970s and is thus well over 40 years old. It was built for the Initial Cooling Experiment (ICE) where stochastic and electron cooling were tested to ascertain the feasibility of using these tec...

description The current electron cooler at the Antiproton Decelerator (AD) at CERN was built in the second half of the 1970s and is thus well over 40 years old. It was built for the Initial Cooling Experiment (ICE) where stochastic and electron cooling were tested to ascertain the feasibility of using these techniques to generate high intensity antiproton beams for the SPpS. The ICE electron cooler was subsequently upgraded and installed in LEAR (Low Energy Antiproton Ring) to help generate intense beams of antiprotons at low energies. After the stop of the antiproton physics at LEAR in 1996 and two years of studies of electron cooling of Pb ions, the electron cooler was moved to the AD where it has been in use ever since. With the new ELENA ring becoming operational, a major consolidation project has been launched to extend the life of the AD and as a part of this a new electron cooler for the AD is being built. In this paper, we describe some of the design considerations and challenges of this project as well as the expected gains in terms of cooling performance.
