THPAM1R3	Status of E-Cooling Characterisation at 100 keV in ELENA	40

	The Extra Low ENergy Antiproton ring (ELENA) ring at CERN was commissioned in 2018 and is in regular production operation from 2021. ELENA uses e-cooling for cooling pbar beams on two plateaus at 653 keV and 100 keV kinetic energy. The first cooling is necessary to allow for efficient deceleration of the 5.3 MeV pbar beam coming from the Antiproton Decelerator (AD), while the second cooling is used to define the quality of the bunches before extraction. The experience accumulated so far shows that cooling at 653 keV is sufficient to ensure good deceleration efficiency, while cooling at 100 keV might not be sufficient to provide the design transverse beam emittances at extraction. In this paper we document the present ELENA e-cooling performance at 100 keV, the typical optimisation procedure used during setup, and we investigate possible limitations of the present system.

	P.M. Kruyt, D. Gamba CERN, Meyrin, Switzerland G. Franchetti GSI, Darmstadt, Germany
	This paper presents the current status of cooling simulation tools and their advancements and applications, with a focus on Xsuite, a new simulation tool developed that includes cooling, space charge, and intrabeam scattering. The paper covers the capabilities of cooling simulation tools, recent advancements, and their impact on the field of beam cooling. The interplay of different cooling techniques with heating effects is discussed, and predictive models for existing and future electron cooler performance optimization are presented. The feasibility of laser cooling in the CERN storage rings is also assessed, with a focus on future project proposals in the frame of the Physics Beyond Colliders (PBC) project.

The Extra Low ENergy Antiproton ring (ELENA) ring at CERN was commissioned in 2018 and is in regular production operation from 2021. ELENA uses e-cooling for cooling pbar beams on two plateaus at 653 keV and 100 keV kinetic energy. The first cooling is necessary to allow for efficient deceleration of the 5.3 MeV pbar beam coming from the Antiproton Decelerator (AD), while the second cooling is used to define the quality of the bunches before extraction. The experience accumulated so far shows that cooling at 653 keV is sufficient to ensure good deceleration efficiency, while cooling at 100 keV might not be sufficient to provide the design transverse beam emittances at extraction. In this paper we document the present ELENA e-cooling performance at 100 keV, the typical optimisation procedure used during setup, and we investigate possible limitations of the present system.
