Speaker: Davide Gamba (BE-ABP)

The Extra Low ENergy Antiproton storage ring (ELENA) is an upgrade project at the CERN AD (Antiproton Decelerator). The smaller ELENA ring further decelerates the 5.3 MeV antiprotons coming from the AD down to 100 keV. This will allow for up to two orders of magnitude increase in trapping efficiency at the antimatter experiments hosted in the AD hall. ELENA features electron cooling for emittance control during the deceleration and therefore preserve the beam intensity and to generate bright bunches extracted towards the experiments.

The ring has been completed with the installation of the electron cooler at the beginning of 2018. Beam commissioning with cooling started shortly after, and decelerated beams with characteristics close to the design values have been obtained before the start of LS2.
During LS2 electrostatic transfer lines from the ELENA ring to the experimental zones will be installed, replacing the magnetic transfer lines from the AD ring.
In this seminar, we will give an overview of the ELENA project and design, and we will report on the status of the beam commissioning and on the plans for LS2.

Start time: 2:30 p.m.

Coffee will be served before the seminar, at 02:15 p.m.
