Description
A new electron cooler, replacing the 40 years old one, will be installed starting in 2027, during Long Shutdown 3, in the CERN Antiproton Decelerator ring. The new electron cooler aims to improve reliability, cooling time and beam losses. The design of the new electron cooler, very similar in geometry, electron intensity and energies to the present device, will add electron beam magnetic expansion from the gun to the cooling section and enhance the field quality in the cooling section so to reduce electron transverse energy; approach the H/V orbit corrector magnets and improve relative position measurement of the antiproton and electron beams so to better center the two beam; allow faster switching of the electron beam on/off at the gun so to ease operations. Ultimately, the testing strategy will ensure highly reliable operations. This paper presents an overview of the status of the project.
