The University of Washington group that made its reputation by doing measurements of exquisite precision on single protons, electrons and positrons held for astonishingly long times in a Penning trap (PHYSICS TODAY, May 1985, page 17) has finally succeeded in trapping antiprotons. They accomplished this feat in July at the LEAR low‐energy antiproton ring at CERN, where they had been granted one day's running to do a feasibility test for precision antiproton measurements they hope to carry out next year.
