N2 - Magnetized Rydberg positronium forms when an energetic positron (e+) slows within a tungsten crystal and picks up an electron (e−) as it emerges in a strong magnetic field. The signature is equal numbers of e+ and e− when a weak electric field is applied, either of which can be accumulated and counted. The new e+ accumulation technique is simple, robust, and much more efficient than any other demonstrated to be compatible with a cryogenic vacuum. Possible applications include the study of cold single component plasmas of e+ and the formation of cold antihydrogen.
