Measurements have been made of the energy distributions of protons passing through NaCl, KCl, Si, and Ge single crystals at various angles with respect to the {100} and {110} planes. The fraction of protons passing through lattice channels has been evaluated, and its dependences on the angle of incidence, the chemical composition of the sample, and the proton energy have been found.

The effects of the amplitude nonuniformity of the magnetic field in a betatron on the forced and betatron radial oscillations of electrons during extraction (or discharge toward the target) at the end of the acceleration cycle are examined. The amplitude and phase dynamics of radial betatron oscillations are studied by means of an analog computer.

High-alumina, zircon, chamotte-kaolin, zirconia, and clay-graphite end nozzles were tested in a semi-continuous casting plant during the pouring of stainless steel in the pouring device, and SP-25 high-alumina and zircon nozzles were tested in the intermediate ladle.

Some preliminary experimental results on the acceleration of plasma in circular waveguides are reported. The experiments were carried out in the 10-cm region with H01 and H11 waves and with various plasma injectors. Plasma bunches with an initial particle concentration of 1012 cm-3 and higher were injected with an initial velocity of 5 × 106 cm/sec from a spark source or formed directly on the axis of the waveguide with the help of a pressure differential plasma source ensuring a vacuum in the accelerator corresponding to pressures in the range 10-7 to 10-6 mm Hg. Electric probes, super high-frequency methods and an electrostatic particle energy analyser were employed for diagnostic purposes. Plasma confinement was accomplished by the use of auxiliary external magnetic fields having various configurations. Accelerated ions with energies exceeding 10 keV were obtained.

The angular distribution of electrons having an initial energy of 6.74 MeV has been studied after passage through C, Al, Cu, Sn, and Pb samples having thicknesses in the range in which multiple-scattering theory does not apply.

A study was made of the channeling of 6. 72 MeV protons in a silicon crystal at 100–800 °K. The experimental dependence of the limiting channeling angle agrees with the theoretical prediction. A relation is found between the relative number of channeled protons and the temperature.

A magnetic β-spectrometer has been used for a thorough study of the energy distribution of electrons having an initial energy of 6.74 MeV after passage through C, Al, Cu, Sn, and Pb samples up to 0.5 R in thickness.
