A new approach to the problem of high energy particle detection is described, in which parallel electric and magnetic fields are employed. It appears that a particular regime of operating conditions will allow a very substantial suppression of diffusion transverse to the fields in a suitably prepared drift chamber. If the more optimistic estimates are in fact achievable, single track - segment measurement errors of only a few tens of microns in a volume ~1 m3 should be feasible. Additional benefits are the possibilities of unambiguous spatial reconstruction, as well as high data rate capability, high multitrack efficiency, and easy applica- bility to 4n geometr y. A program is outlined which is designed to gain further experience with the concept, provide needed data about electronic diffusion within various gas/field environments, and hopefully lead to practical detectors.
