M-H of CORC and twist stack in full penetration calculated by Analytic and FEM methods For long Lp, Mcorc = Mtwst = (2/)Mtape In general Hall probe short cable system online 3 T dipole system for 30 cm cable magnetization/loss online Drift suppression for YBCO with cycle modifications Further Measurements of the most recent cables, expanded up to +- 3 T at 4 K Expressions for CORC Magnetization at arbitrary fields near injection have been developed as part of LBNL-OSU collaboration (X. Wang) YBCO data for error estimations
