Evidence that transverse variability of critical current density can greatly mitigate screening current stress in high field REBCO magnets
Published 2024-12-01“…Abstract Plastic damage of REBCO (REBa2Cu3O7-x, where RE=rare earth) coated conductors by screening current stress (SCS) is a significant concern for ultra-high-field superconducting magnets. Indeed, the third Little Big Coil (LBC3), a REBCO magnet that generated a record, high field of 45.5 T, showed wavy plastic damage produced by excess SCS in all pancakes except two made with single-slit conductors having their slit edges pointing inward towards the magnet center. …”

Mechanical Behavior of Pericopsis elata Relative to Age during Growth
Published 2021-01-01“…Trees ready for harvesting are scarce because the logging diameter, which has been set at 100 cm, is very big. The studies recommended by the Cameroonian government as part of the ITTO/CITES project activities should be carried out to determine a new minimum logging diameter as the diameter increases with age. …”
