Invited Oral Presentation

At Helmholtz Insitute Mainz (HIM) a high voltage platform for high intensity electron beams has been installed. This apparatus is intended as a scalable, modular system for high energy magnetized DC-beam cooling. On the one hand, the system can be used as a prottype for antiproton beam cooling for the planned HESR storage ring at FAIR. On the other hand, because the HESR will be delayed, ...

Invited Oral Presentation

The electron cooler of the Antiproton Decelerator (AD) at CERN, that can operate with an electron beam of up to 2.4 A at 27 keV, is scheduled for replacement during the upcoming Long Shutdown 3 (LS3). A newly designed electron gun and collector—optimized for enhanced reliability, efficiency, and operational performance—are undergoing rigorous testing and validation at the dedicated Electron...

Contributed Oral Presentation

Field emission-based cathodes have been shown to be an attractive alternative to thermionic sources for the generation of electron beams. Their low transverse energy spread, and low power consumption make them an ideal replacement for the thermionic cathode currently used on the electron cooler of the Extra Low ENergy Antiproton (ELENA) ring.
We have investigated the use of carbon nanotubes...
