Overview

Short description of work of sub-task 2

High temperature superconductors offer new possibilities as active or passive shield for polarized nuclear gas targets. First numerical calculations in the ‘Helmholtz-Institut Mainz’ (HMI) have shown that high temperature super-conductors like YBCO or BSCCO are ideal materials to passively shield a strong magnetic detector field. Simulations and test with different materials and different geometries will be performed in the framework of this WP in order to find the optimum geometry and working point in terms of a transversely polarized target. The use of high temperature superconducting materials in thin cylindrical layers to shield magnetic fields is a demanding and challenging high-tech application of HTCS in terms of the sintering and machining of the superconductors in nonstandard small geometries.
