Investigation of Dual Polarization Reflectometry for Determination of Plasma Density and Magnetic Field in a Spherical Tokamak

The paper deals with dual polarization reflectometry as a method for determination of plasma density and poloidal magnetic field profile in low aspect ratio tokamaks. A numerical iteration algorithm is developed and solutions for integral equations for O- and X-modes are presented. The numerical calculations confirm the use of the iterative algorithm for effective reconstruction of the density and magnetic field profile.

Effect of ultraviolet irradiation on the formation of cracks in BaTiO3

A previously unknown physical effect is described of UV irradiation impeding the growth of the cracks that originate, upon indentation, in an a-single-domain BaTiO₃ crystal.     

Fast magnetosonic and fast Alfvén waves in an elliptic plasma cylinder

The propagation of ion-cyclotron waves in an extended cylindrical plasma is analyzed analytically. The results obtained show progress in constructing a two-dimensionally-nonuniform analytical theory. Pis’ma Zh. Tekh. Fiz. 25, 33–38 (September 26, 1999)     

Admixture transport inside a cylinder at a variable stream velocity and during a transient gas transfer to the wall

Results are shown of a theoretical and experimental study concerning the convective-diffusive transport of a sorbed admixture in a channel where the stream velocity varies with time and where a transient transfer of gas to the wall occurs.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 23. No. 5, pp. 898–901, November, 1972.     

Anomalous bexavior of fracture toughness of ferro-electrics in the phase transition region

Temperature dependences of fracture toughness of some ferroelectric crystals have been studied both experimentally and theoretically. It is argued that its anomalous behavior in the phase transition region may be related to the presence of the piezoeffect in the ferrophase.
