Resistive cooling of He[sup +] ions has been studied in a 4 K Penning trap optimized for [omega][sup +] cooling. A Nb/Ti superconducting inductor gives a Q of 1800 resulting in energy cooling time constants as low as 1.8 seconds and the cooling has been followed from 60,000 K to 300 K. In a separate study in a room-temperature trap, the possible conversion of H[sup +] to H[sup [minus]] at a cesiated trap electrode and subsequent capture of the H[sup [minus]] by fast reversal of the trap electrode polarity was not yet proved to be a workable mechanism. Features of the apparatus and technique are briefly described and the details are continued in three publications attached as appendices.
