developed to provide fast 3D cooling of hot secondary beams (anti-protons at 3 GeV and rare isotope ions at 740 MeV/u) at intensities up to 108 particles per cycle. For antiproton cooling, cryogenic plunging [...] COOL 2015 , Newport News, VA, USA DOI:10.18429/JACoW-COOL2015-MOYAUD04 Stochastic Cooling Of Heavy Ions In The HESR R. Stassen, B. Breitkreutz, G.
