Abstract: On July 13, 1989 the BEAM experiment Aboard Rocket (BEAR) linear
accelerator was successfully launched and operated in space. The flight
demonstrated that a neutral hydrogen beam could be successfully propagated in an
exoatmospheric environment. The accelerator, which was the result of an
extensive collaboration between Los Alamos National Laboratory and industrial
partners, was designed to produce a 10 mA (equivalent), 1 MeV neutral hydrogen
beam in 50 microsecs pulses at 5 Hz. The major components were a 30 kev H-
injector a 1 MeV radio frequency quadrupole, two 425 Mhz RF amplifiers, a gas
cell neutralizer, beam optics, vacuum system and controls. The design was
strongly constrained by the need for a lightweight rugged system that would
survive the rigors of launch and operate autonomously. Following the night the
accelerator was recovered and operated again on the laboratory.
