Compressive Residual Stresses

This paper addresses the thermal-mechanical properties and performance characteristics of full tension splice connectors under high temperature operation, in particular those used in overhead transmission and distribution lines. Due to the increase in power demand existing overhead power transmission lines often need to operate at temperatures higher than those originally considered for their design. This has led to the accelerated aging and degradation of splice connectors. The compressive residual stresses induced by the crimping process within the splice connector provide the clamping forces to secure the conductor and therefore, the determination of the state of compressive residual stresses in splice connectors is a necessary requirement to provide an accurate estimate of their service lifetime. This paper presents a protocol for integrating analytical and experimental approaches to evaluate the integrity of a full tension single-stage splice connector assembly.

Tes Detectors

ACTPol, a polarization sensitive receiver for the Atacama Cosmology Telescope, is designed to make sensitive maps of the cosmic microwave background anisotropies at arcminute scales and millimeter wavelengths by employing three arrays of superconducting transition edge sensor (TES) detectors. The ACTPol TES bolometers have a target superconducting transition temperature of 150 mK and will be cooled to a bath temperature of 100 mK with a dilution refrigerator enabling increased array sensitivity. Each array will consist of ~1000 TES detectors coupled to a micromachined silicon feedhorn stack via superconducting ortho-mode transducers and transmission lines. The superconducting detectors of the first ACTPol array have been characterized in their final receiver configuration with measurements of key TES parameters including the transition temperature, saturation power, and thermal conductance.
