Filament-induced breakdown spectroscopy (FIBS) is an
attractive remote detection approach that is potentially
applicable to nuclear materials, such as uranium (U). Simultaneous
detection of atomic U and uranium monoxide
features is demonstrated in a single laser shot with
detection probabilities of 52.2% and 39.0%, respectively,
and with a 1% false-alarm probability. It is shown that a
nearly 100% detection probability can be reached with
1% false alarm probability in .1 second when using an
80-Hz laser and data acquisition system. Atomic U and
UO signal features are identifiable in the remote measurement
with comparable signal-to-background ratios,
suggesting that, despite being broader than the U I
emission line, the UO band is also suitable for remote
detection of uranium by FIBS.
