“…T HE SUPERCONDUCTING magnets cooled at 4.2 K and lower used for many apparatus have been designed in the last several decades [1], [2]. The discovery of high-temperature superconductivity also has sparked a great deal of interest in its application to electrical power system since 1980s [3].…”

The performance of dielectric materials has an important effect on influencing the service life of the electric equipments. The dielectric sheets used for superconducting devices usually endure several lapping tension when lapped on the conductor, so the AC and impulse dielectric strengths of polymer sheets under tensile status are important to dielectric design. In this paper, a special electrode system was designed to measure the AC and impulse breakdown voltages of polyimide and poly tetra fluoro ethylene (PTFE) sheets under tensile status both in air at normal temperature and in liquid nitrogen at 77 K. The test data are processed by the method of Weibull plot. As a result, the AC dielectric strengths of polyimide sheets in liquid nitrogen at 77 K increase significantly as the tensile stresses increasing, the most amplitude achieves 29.16%. The impulse dielectric strengths of two polymer sheets all decrease little as the tensile stresses increasing. The AC and impulse dielectric strengths of polyimide under tensile stress are significantly higher than PTFE in liquid nitrogen at 77 K, Polyimide has good dielectric characteristics under tensile status in liquid nitrogen at 77 K.Index Terms-Dielectric strength, liquid nitrogen environment, tensile status, Weibull plot.

“…The first one is to superpose a number of counter-wound double layer coils of the type described before and connect them in series. The second is to counter-wind just one double layer coil but now using instead of the single wire a flat cable composed of several wires glued in parallel, like already experienced in [4], again making serial connections at the end. Such cables appeared to be very tough and to accept all kinds of bends and torsions.…”

Abstract-The Large Hadron Collider (LHC) needs more than 6000 superconducting corrector magnets. These must be sufficiently powerful, have enough margin, be compact and of low cost. The development of the 11 types of magnets was spread over several years and included the magnetic and mechanical design as well as prototype building and testing. It gradually led to the systematic application of a number of interesting construction principles that allow to realize the above mentioned goals. The paper describes the techniques developed and presently used in practically all the LHC corrector magnets ranging from dipoles to dodecapoles.
