The CERN Antiproton Decelerator (AD) has now completed it’s 12^th year of supplying low-energy antiproton beams for the successful physics program. Most of the machine’s key components are in operation since more than 25 years and prompted by the approval of the ELENA project, a substantial consolidation program is now being launched to ensure continued reliable operation. Over the course of the next few years a progressive renovation of the AD-Target area and the AD-ring with all the associated systems will take place. Status and performance of the AD are presented along with an overview of planned and ongoing consolidation activities with emphasis on stochastic and electron beam cooling.

The LEIR electron cooler was successfully commissioned in 2006 and is used to routinely cool and accumulate high brightness beams of Pb⁵⁴⁺ ions for the LHC. Some initial measurements on the performance of the device were reported in 2007 but did not fully study the influence of the electron beam current and density distribution on beam cooling. We present a compilation of measurements performed over the last years during dedicated machine study sessions which aim to shed some light as to the effectiveness of electron cooling with hollow beams.

The Extra Low Energy Antiproton ring (ELENA) is a small ring at CERN which will be built to increase substantially the number of usable antiprotons delivered to the experiments for studies with antihydrogen and antiprotonic nuclei. The project is now at stage of finishing the technical design. This presentation reviews the major features of ELENA: the ring, transfer lines and experimental area layout, the choice of the basic machine parameters and the main challenges. Electron cooling plays a key role in ELENA both for efficient deceleration as well as for preparing the extracted beam with parameters defined by the experiments. The choice of machine optics as a tool for achieving the required parameters and fitting the available space is discussed. The important systems like the magnets, vacuum, beam instrumentations and others are reviewed as well.
