Some shots have been done for Livermore by LASL.
In the 10" diameter
a velocity of one millimeter/microsecond was obtained.
Various calcula-
tions about shock, reflected shock, and the time behavior of alpha were
mentioned, f

In reply to Dr, MacDougall, Dr. York said that the weights and
lengths given included the warhead only, with no electronics, except
that the 240 lb figure was for a complete g" shell,
A test shot program for this development has not yet jelled,
Possible

The
current thinking is to make one quite conservative shot (nob a prototype),
to be followed by a second shot,

In the hydride program, Livermore was exploring the possibilities
Hydride
Program
of substituting UH, for U metal. The critical massis smallervith
hydride but the nultiplieation
factor is less,
So far, it appeared
that in a 16" diameter about half the yield could be obtained, at halt
the price,
However, the situation was very uncertain,
Various fabrica~
tion and handling methods are being investigated.
There were a number of questions and some discussion about the
ideas Dr. York had reported,
This final session of the combined briefings closed at 4:20 p.m,
