Influence of nonstoichiometry on the thermal conductivity of boron carbide

It is shown that the deviation of the boron carbide composition from stoichiometry results in a change in its thermal conductivity.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 32, No. 3, pp. 414–417, March, 1977.

Determination of electrodynamic parameters of the period of an accelerating structure with spatially periodic radio-frequency quadrupole focusing

The abandonment of a constant radio-frequency voltage across acceleration periods of the structure with a spatially periodic radio-frequency quadru pole focusing substantially expands the applicability range but complicates the tuning process of dynamic parameters. The possibility and necessity of applying the calculation is shown, when the accelerating structure is tuned. A procedure for calculating electrodynamic parameters of the acceleration period is proposed. The theoretical and experimental results are compared.
