Abstract
High-current superconducting conductors are widely used in fusion magnets, high energy accelerators and high magnetic field facilities. A new test facility is developed to carry out experimental research on DC performance of new conductors. In order to prevent the sample conductors from premature quenches due to mechanical disturbance under the magnetic field, it is necessary to apply a certain transverse stress to the sample through sample support. In this paper, two different kinds of transverse stress applying technologies are developed. The general design of these two kinds of sample supports, the influence of cooling and powering process on sample transverse stress with active sample support, the assembly gap analysis of passive sample support are described in detail. Considering the stability margin of conductor sample and the influence of transverse stress on performance of the sample, the selection basis of transverse stress at room temperature is summarized.
