  An induction unit, followed by frictional cooling, is applied to the antiproton bunches delivered by CERN's antiproton decelerator (AD) at 5 MeV. The scheme requires about 1 meter of induction unit to reduce a fraction of the 200 ns pulse to 60 keV after which frictional cooling, involving a set of thin foils, reduces the anti-protons to about 5 keV where they can be captured in an anti-proton trap. The scheme is compared to a further de-acceleration ring (such as ELENA) and to a degrading foil from the 5 MeV of the AD alone. Theory and simulations provide a preliminary assessment of the concept's strengths and limitations. The comparisons are limited largely by poorly-known levels of multiple scattering of low-energy antiprotons and experimental experience is employed.
