✦ Synopsis

Electron cooling is a well-established technique to increase the phase space density of particle beams in storage rings. In this paper, we discuss the feasibility of electron and positron cooling of ions in a Penning trap. We calculate the cooling times for the cases of trapped bare ions with nuclear charge Z ¼ 1 (protons), Z ¼ 36 (krypton) and Z ¼ 92 (uranium) with the Spitzer formula. Our calculations show that for typical experimental conditions the time for cooling from initial energies of 10 keV per charge down to rest is in the order of a second. We investigate the dependence of the cooling time on the number of ions and electrons, and their charge and mass.

After a brief introduction to the electromagnetic ion trap, we concentrate on the problems related to precise determination of cyclotron fhquencies of stored ions. Since these frequency measurements are performed in order to obtain mass ratios we want to point out the inherent difficulties in detect
