High Temperature Superconductor (HTS) Tape Manufacturing Equipment
SuperCurrent™ Ic Measurement System
Description
Cryogen-free automated critical-current (Ic) measurement system for QA and characterisation of HTS wire and tape in production and development. Integrates a high-field split-pair magnet with a full transport-measurement setup for Ic(T, B, θ), n-value, and R(T) on 1G, 2G (ReBCO), and MgB₂ conductors — the platform behind the Robinson Research Institute HTS wire database.
