testing of electronic components and systems, this reactor has been used in a
wide variety of research activities. Experiments are conducted not only in the
cavity but also outside the core at distances between 0.3 and 3.0 m from the core
axis. There are also ports in the shield wall in order to support experiments that
require collimated beam geometries. The reactor can be operated in steady state
(up to 10 kW power) or pulsed mode (10 MJ in an 80 μs FWHM (full width at
half maximum) pulse that yields approximately 5 × 10 14 n/cm 2 in the cavity). This
fast burst 235 U metal assembly has a very similar neutron spectrum to the 235 U
thermal fission reference benchmark field, but has a larger thermal component
