Abstract In superconducting magnets, soldering splices are used to connect superconducting cables for providing electrical current paths. One of the main considerations in the splice design is the splice electrical resistance across the joint. High joint resistance can increase the Joule heat generation and thus result in conductor instability. A finite element analysis has been performed to determine the key parameters affecting soldering splice resistance for superconductors with high purity aluminum stabilizers. The parameters investigated include: high purity aluminum RRR value, copper RRR value, solder layer thickness, magnetic field, splice configuration, and operating temperature. The results obtained from this work can benefit splice cooling and the design optimization.

Auerbach, Callendar, and I think also Tait, have observed that the temperature coefficient of electrical resistance of iron is abnormally high. So far as I know no one has pushed his observations to the temperature at which iron ceases to be magnetic.

Monte Carlo Calculations

The thickness dependence of the absolute temperature coefficient of the resistance of ultra-thin metal films is calculated with the help of Monte-Carlo calculations already successfully applied to the simulation of the electrical resistance. An initially strong increase and then a weaker decrease of the ATCR with increasing thickness is found.

In order to investigate the influence of (Bi0.5M0.5)TiO3 (M=Li, Na, K, Rb) addition on the Curie temperature (Tc) and positive temperature coefficient (PTC) effect of BaTiO3-based ceramics, BaTiO3-(Bi0.5M0.5)TiO3 (M=Li, Na, K, Rb) solid solutions were prepared by a conventional solid sintering reaction using high-purity reagents. It was found that the Tc of the samples would vary with (Bi0.5M0.5)TiO3 of different alkali ions, in which BT-BKT ceramics had the highest value (about 148 °C). Moreover, the incorporation of alkali ions would influence the PTC effect of the sample, which can be defined by the resistivity jump with the ratio of maximum to minimum resistivity (ρmax/ρmin). Under the present conditions, the ρmax/ρmin of BT-BRT and BT-BLT ceramics were almost equal and higher than those of BT-BNT and BT-BKT ceramics.

Abstract TECHALLOY 294 is a copper-nickel alloy with constant electrical resistance over a wide range of temperatures. It is used widely in rheostats and controls where the maximum operating temperature does not exceed 1000 F. Its low temperature coefficient of electrical resistance and its stability make it highly useful in sizes for instruments and resistors. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-301. Producer or source: Techalloy Company Inc..
