Abstract

Allowing for a field-dependent critical current density, the authors calculate the magnetic field that can be supported by hollow cylinders of varying wall thickness. An adiabatically stable field of 1.0 T can be shielded by or trapped in a cylinder with a wall thickness of 0.4 cm if the critical current density varies linearly with magnetic field and has a value of 10⁴ A/cm² at a field of 1.0 T. Such a current density appears to be within reach of present state-of-the-art melt-processed YBa₂Cu₃O₇ (123) materials
