Abstract
A rf-driven discharge is used to produce a beam of metastable krypton atoms at the 5s(3/2)(2) level with an angular flux density of 4x10(14) s(-1) sr( -1) and most probable velocity of 290 m/s, while consuming 7x10(16) krypton atoms/s. When operated in a gas-recirculation mode, the source consumes 2x 10(15) krypton atoms/s with the same atomic-beam output. (C) 2001 American Institute of Physics.
