We have developed an optical diagnostic system suitable for characterizing the
performance of energetic neutral beams. An absolutely calibrated CCD video
camera is used to view the neutral beam as it passes through a relatively high
pressure (10-5Torr) region outside the neutralizer: collisional excitation of
the fast deuterium atoms produces H. emission (A=6561A) that is proportional
to the local atomic current density, independent of the species mix of
-accelerated ions over the energy range 5 to 20keV. Digital processing of the
video signal provides profile and aiming information for beam optimization.
