Description

A new electron cooler for the antiproton decelerator (AD) ring at CERN is under construction and will be installed in the next long shutdown (2026-2028) to replace the existing 40-year-old device. This paper presents the design of the new electron cooler magnet system, justifies key design choices, and details the performance. Compared to the existing electron cooler magnet system, the new magnet system gives a factor five improvement of drift region field quality and includes provision for electron beam expansion. The upgrade has the potential to reduce the length of the electron cooling plateaus in the AD cycle and thereby increase the number of antiprotons available to CERN's rich antimatter physics program.
