## Title

- title: Critical Current Measurements on Round Cables Made With a REBCO Stack Conductor
  title_type: original
  lang: en

## Description

- description: When a commercially available coated conductor with a substrate thickness
    of 30 µm is applied to the CORC®, the minimum core diameter is approximately 2.4
    mm without any degradation in the critical current (Ic). Because the engineering
    current density of the CORC® is highly dependent on the core diameter, the cable
    with a smaller core is desirable to achieve compact coil windings for high-field
    accelerator magnets. In this study, a REBCO stack conductor, made by soldering
    two coated conductors with their REBCO layers facing each other, was applied to
    the round cable instead of the commercially available single coated conductor.
    This REBCO stack conductor allows the REBCO layer to be closer to the neutral
    axis of the conductor, thereby reducing the strain induced in the REBCO layer
    by winding the conductor on the core. As a result, the REBCO stack conductor can
    be wound on a smaller core than the CORC®, allowing for higher current densities.
    This paper presents the magnetic field dependent Ic of the coated conductor at
    4.2 K, the cable Ic and estimated strain of the REBCO layer as a function of the
    core diameter at 77 K, and the calculated cable current density made with the
    stack conductor.
