METHOD AND DEVICE FOR ACCURATELY MEASURING THE INCIDENT FLUX OF AMBIENT PARTICLES IN A HIGH OR ULTRA-HIGH VACUUM ENVIRONMENT

摘要

An apparatus and method that can measure flux density in-situ under high vacuum conditions includes a means for confining a collection of identical, elemental sensor particles to a volume of space by initial cooling by laser or another method, then confinement in a sensor volume using externally applied magnetic and/or optical fields.
