[en] The magnetized kinetic equation derived in an earlier paper (Hassan and Watson, 1977) is used to study the problem of relaxation of anisotropic electron and ion temperatures in a magnetized plasma. In the case of anisotropic electron temperature relaxation, it is shown that for small anisotropies the exchange of energy within the electrons between the components parallel and perpendicular to the magnetic field direction determine the relaxation rate. For anisotropic ion temperature relaxation it is shown that the essential mechanism for relaxation is provided by energy transfer between ions and electrons, and that the expression for the relaxation rate perpendicular to the magnetic field contains a significant term proportional to ln eta₀ ln (msub(e)/msub(i)) (where eta₀ = Ωsub(e)/ksub(D)Vsub(e perpendicular to)), in addition to the term proportional to the Coulomb logarithm.

[en] The design of a computerized, robust probe to measure the heat capacity of bulk superconductors from 4 K up to room temperature in small bore high field magnet is described. The measurement combine the high sensitivity of a.c. calorimetry, required for investigating variations in Cp near phase transitions, with the accuracy of heat pulse calorimetry. Data are presented for Copper and NbTi in magnetic fields up to 10 Tesla. A typical accuracy of about 3% and sensitivity of 0.1 - 0.5% are achieved. (author)

[en] The adaptability of multifilamentary V₃Ga wire for AC use has been studied. The residual gallium concentration in the matrix after the V₃Ga formation is 14-16 at% depending on the heat treatment condition. The electrical resistivity of Cu-14 at% Ga alloy is three times as high as that of the Cu-Sn alloy matrix of Nb₃Sn wire after the heat treatment, which is advantageous to reduce coupling current between filaments. The hysteresis loss of the V₃Ga wire decreases with increasing heat treatment temperature and with grain growth of V₃Ga. The hysteresis loss of V₃Ga layer itself is nearly the same of smaller than that of bronze-processed Nb₃Sn layer. Present study has revealed that the V₃Ga wire seems to be promising for AC applications
