This document introduces the technical specifications of MRBR 7.0 TESLA / 160mm ACTIVELY SHIELDED ROOM TEMPERATURE BORE MAGNET SYSTEM.
This document provides technical specifications for the Magnex MRBR 7.0 Tesla actively shielded room temperature bore magnet system. The system features a multi-coil superconducting magnet housed in a low-loss cryostat, designed for high field homogeneity and stability. Field shimming is achieved through a combination of superconducting shim coils and passive shim pieces.
| Central field | 7.0 Tesla |
|---|---|
| Field stability | < 0.05 ppm/hour |
| Operating current | 252 Amps |
| Time to energise | Less than 120 minutes |
