Stability of a Linear Pinch With a Thick Boundary
The stability of a linear pinch is investigated by means of the "6W" formalism of E. A. Frieman. It turns out that when attention is confined to the surface layers of the plasma, convenient stability criteria can be deduced for very general cylindrically symmetric distributions of magnetic field and plasma.

A Proposal For Reducing Impurities in a Stabilized Pinched Discharge
It is proposed to reduce the initial wall hangup and consequent plasma contamination of a stabilized pinched discharge by reducing the Bz pressure difference across the current sheath to nearly zero at early times. Two methods for accomplishing this are proposed, both involving multistage programming of the Bz system.

Fast Neutron Cross Sections: Corrections to LA-1714 and a Correlation of 3 Mev Values
Recent measurements on the long counter efficiency in which comparisons were made with the (n, p) scattering cross section, additional variations in efficiency were found which varied slowly with neutron energy but were still correlated with the total neutron cross section of carbon. Because of these variations in efficiency there are errors in the fission cross sections reported in LA-1714. Corrections to these data have been given here.

Preparation of Plutonium Sheet by Extrusion
Plutonium sheet of uniform thickness and good surface can be made by the extrusion of a tube which is then split and flattened. This report describes the equipment and the operating conditions for making sheet 0.005 to 0.055 in. thick with areas up to 24 in. square.

Neutron Emission Probabilities From the Interaction of 14-Mev Neutrons With Be, Ta, Bi, and U238
The spatial and spectral distributions of the neutrons from 14-Mev neutron interactions with Ta, Bi, and U have been obtained using nuclear emulsion detectors in conjunction with a neutron collimator. The space-integrated neutron spectrum has been obtained for Be by means of a sphere experiment.

Solution of the initial value problem for the linearized multi-velocity transport equation with a slab geometry
From preface: "This thesis treats an initial value problem which arises in many branches of physical science, namely the one stemming from the velocity-dependent integro-differential transport equation."

Radioactive Decontamination Tests on Surgeon's Gloves Contaminated With Plutonium
Report discussing the effectiveness of various methods for removing plutonium from contaminated gloves. The cost of decontaminating the gloves using the most effective method was three times the cost of new gloves, and "consumer resistance" was noted among users of treated gloves.
