Electron cooling antiprotons to thermal energies in a Penning trap

We investigate a anti p trapping scheme based on stopping foils which, in the simplest case, require no auxiliary decelerator/cooler past a LEAR (or equivalent) stage. Cooling of the trapped particles could be accomplished via the damping provided by an external resistor as in all of the other experiments. The rate for this cooling would be rather low, and likely would be much lower when the electrostatic anharmonicity of such a trap is realistically considered. (orig./HSI)
