Some measurements have been made
that indicate the neutron flux and
power distributions in various parts
of the array. The flux was measured
in the usual manner with base- and
cadmium-covered- indium foils and the
power or fission-rate data were derived
froin fission fragments collected on
aluminum foils placed in contact with
the uranium.

and in Fig. 5.4 are the data obtained
along a central traverse of cell 0-12,
perpendicular to the mid-plane. In
both cases, the activations of bare-
and cadmium-covered- indium foils and
their difference are shown. These
results are typical of t,hose obtained
