DOi,(z) = dose in oil at z cm from the
source,
DM(z + t) = dose in
of shield and z cm of oil,
ho(z) = relaxation length of oil at z cm,
hM(z + t) = relaxation length behind the shield
and in oil at (z + t) cm,

h = average of ho(z) and AM(” -i- t) ,
a = source radius = 35.56 cm,
Zt = (Zt), + (Zt)ss, the sum of macroscopic
removal cross sections of
sample and container, where the
subscript “ss” refers to the stainless
steel walls of the lithium
tank.
Stainless steel was assumed to be the same as
iron (aR = 1.98 barns/atom). The numerical values
for these terms are given in Table 13.1.
GE-ANP HELICAL AIR DUCT
EXPERIMENTATION
J. M. Miller
The GE-ANP helical air duct experimentation
at the LTSF has continued with thermal-neutron
flux measurements beyond a 35-duct array. As
described previously,6 the ducts are 3-in.-llD steel
