The power of nuclear track research emulsion as a fast neutron dosimeter is examined in the exposure of a human phantom to PuBe neutrons. Semiautomatic track scanning and high-speed data analysis obviate the major disadvantages of this dosimeter, and allow the following basic information to be obtained without a serious cost in time: the rulative proton recoil energy spectrum, the absolute differential proton track den sity spectrum, and the average proton recoil energy at various locations in the phantom. From this are calculated the total absorbed local tissue doze due is proton recoils, the local thermal neutron intensity, and that portion of the tissue doze due to thermal [formula] tracks.

The relative yield of neutral photopions from various elements was determined as a function of the quantum limit energy of the Berkeley synchrotron. Single decay photons from neutral pions were observed at 45, 90, and 135 deg to the incident bremsstrahlung in the laboratory system. Mean free paths for neutral pions in nuclear matter were obtained, an optical model prediction of the photopion yields based upon pion-nucleus scattering data was confirmed, and the presence of coherent pion production in the forward direction was detected.

The response of a two silicon p-n junction diodes has been measured for protons up to 13.3 Mev. In one case the dependence of depletion layer thickness with bias voltage was found to be T or V(0.46). The observed resolution, made up of contributions from crystal noise, beam width, and scatterer thickness, was about 1% for 9-Mev protons.

From abstract: "Plamons (plasma-magnetic entities) are toroidal "packages" of plasma wrapped up in their own magnetic field. Experimental evidence for the existence of plasmons is adduced and theoretical considerations concerning their various types and their stability are discussed."

Report discussing the trajectories of blobs of plasma as it travels across a magnetic field. Various observations are made about the blobs, such as the fact that they are diamagnetic, and that they can be either elastically scattered from each other or form a compound entity with a possible toroidal structure. "It is believed that these blobs are actually stable configurations of plasma and magnetic field, having both diamagnetic moment and spin."

This study is concerned with a class of circuits which employs two tubes in a series connection--sometimes referred to as the stacked-tubes connection. This study will be concerned with two configurations that have shown considerable promise in the field of high speed circuitry. In Part I a configuration called the dynamic plate load amplifier is dealt with. In Part II a configuration called the White cathode follower is examined.

Existing experimental information about the nucleon-anitnucleon interaction is reviewed, and a description is given of a theoretical model, based on the Yukawa theory, which seems able to explain the experimental results.

The following report examines the trapping of charged particles, fast electrons especially, within the geomagnetic field.

Report discussing a study regarding the possibility of using shock ionization as a source for mirror-type thermonuclear reactors. This was tested in a one-inch vacuum system, and though initial ionization and temperature produced was low, the magnetic field extended the time of light emission and compressed the luminous region.

The "near" magnetic induction signal from a nuclear explosion in the earth's atmosphere due to movement of the earth's magnetic field is predicated upon the entrapment of the earth's magnetic flux in the air surrounding the bomb. The entrapment of the flux is due to the initial conductivity of the ionization created by gamma rays. The subsequent movement of the magnetic flux is determined by the hydrodynamics of the expanding fireball so that a spherical hole is blown in the magnetic field distorting the line of force. Slow magnetic field changes of up to 10 gauss occur during 1 second due to be bending of the earth's lines.

Summary: The activity coefficient of Pu(Cl04)4 was measured in perchloric acid solutions. The procedure used was to measure the extraction of the neutral plutonium(IV)-TTA chelate into benzene-TTA solutions at different perchloric acid concentrations. Equations are presented which show the relation of the extraction coefficients, obtained in the above manner, to the activity coefficient of plutonium(IV) per-chlorate. The activity coefficient of Pu(Cl0~)4 is similar to that of a strong acid, e.g., perchloric acid, in that its value increases rapidly when the perchloric acid concentration becomes greater than 2M. The distribution coefficient of TTA between benzene and aqueous perchloric acid solutions was found first to decrease slightly and then to increase two fold as the perchloric acid was varied from 0.01 to 6M. The activity coefficient of the uranous-TTA chelate in benzene was calculated from the results of solubility measurements. The values of the activity coefficient of UK4 are,within experimental error, identical with the values of the activity coefficient of TTA itself.

From abstract: "A relationship is derived that predicts the power radiated from the cathode to the anode of the plasma diode. The radiated power loss predicted by this relationship for a tungsten cathode and a nickel anode at widely different temperatures is found to be five times greater than the prediction of the conventional relationship which assumes gray-body conditions."
