Report discussing experiments on the interaction of neutron-absorber materials and metal matrix materials used in the fabrication of control rods, such as "boron, cadmium, and some of the rare-earth elements such as gadolinium and europium...In order to evaluate the reactions that might occur during fabrication and use, experiments were carried out in which combinations of the various control materials were heated in intimate contact with the several matrices at elevated temperatures."

From abstract: "The motion of a charged particle in a region of crossed electric and magnetic fields is discussed... Possible applications of such a system to various problems in nuclear research are suggested and it is shown to be possible in principle to measure the kinetic energy, mass, and ionic charge of various nuclear-reaction products and to separate various short-lived products for rapid examination. Two different devices are proposed. The application of the technique to investigation of the fission process is specifically discussed."

Report discussing experiments on the photometric determination of various elements in the presence of trace amounts of Uranium.

The following report is a general monthly progress report conducted by the radiation laboratory of the University of California discussing experimental physics, theoretical physics, the MTA target physics program, accelerator construction and operation, biology and medicine, and a plant and equipment report. The period being covered is January 15, 1954 to February 15, 1954.

The purpose of this report is to show the impedance of an approximate equivalent circuit on a complex plan for various constant frequencies and different metals. The equivalent circuit represents a testing coil driven with an AC voltage and a network to represent the impedance of the metal.

Photographic observations of the behavior of uranium dioxide at high temperatures are of great value in designing and evaluating fuel elements. This paper reports the growth of uranium dioxide crystals by vapor deposition during out-of-reactor and in-reactor experiments.

Late in 1958 it became apparent that some fuel elements were failing in the Hanford reactors as a result of water entering through the weld. The mode of entry appeared to be first through a void in the weld, then through a non-wet area or a train of voids in the braze, and finally to the uranium core. Defective closures of a similar nature were also typical of many fuel elements which have failed in the autoclaving operation as shown in Figure 1.

This paper discusses the forbidden and allowed harmonics of a hollow cylinder of barium titanate vibrating in the radial mode.
