A polarized atomic hydrogen beam
Chan, N. and Crowe, D.M. and Lubell, M.S. and Tang, F.C. and Vasilakis, A. and Mulligan, F.J. and Slevin, J. (1988) A polarized atomic hydrogen beam. Zeitschrift fur Physik D, Atoms, Molecules and Clusters, 10 . pp. 393-415.
We describe the design and operating characteristics of a simple polarized atomic hydrogen beam particularly suitable for applications to crossed beams experiments. In addition to experimental measurements, we present the results of detailed computer models, using Monte-Carlo ray tracing techniques, optical analogs, and phase-space methods, that not only provide us with a confirmation of our measurement, but also allow us to characterize the density, polarization, and atomic fraction of the beam at all points along its path. As a subsidiary result, we also present measurements of the relative and absolute efficiencies of the V/G Supavac mass analyzer for masses 1 and 2.
