Approximately 100 $\\mathrm{\\overline{d}}$ per bunch could be delivered as a $100\\,\\mathrm{keV}$ beam based on measured cross-sections. These $\\mathrm{\\overline{d}}$ could be further decelerated to $12\\,\\mathrm{keV}$ using the GBAR scheme, enabling the synthesis of antideuterium ($\\mathrm{\\overline{D}}$) via charge exchange with positronium, a technique successfully demonstrated with $6\\,\\mathrm{keV}$ antiprotons for antihydrogen production.
