This is a technical specification for a 7.0 Tesla / 400mm actively shielded magnet system intended primarily for research studies on the clinical/biological applications of NMR imaging (MRI) and NMR spectroscopy (MRS).
This document provides preliminary technical specifications for the MRBR 7.0/400/AS system, a complete superconducting magnet system designed primarily for research studies on clinical/biological applications of NMR imaging (MRI) and spectroscopy (MRS). The system features a highly homogeneous actively shielded superconducting magnet housed in a horizontal room temperature bore cryostat.
| Central field | 7.0 Tesla (300MHz 'P) |
|---|---|
| Field stability | Less than 0.05 ppm/hour |
| Operating current | TBC Amps (nominal) |
| Homogeneity (Superconducting only shimmed) | Less than 20ppm over 20cm dsv |
| Homogeneity (Fully shimmed using RT shims) | Less than 5ppm over 20cm dsv |
| Helium consumption during ramping | Less than 10 litres |
| Cryostat length | 1900mm nominal |
The system is intended primarily for research studies on the clinical/biological applications of NMR imaging (MRI) and NMR spectroscopy (MRS).
The magnet is wound from multi-filamentary NbTi conductor with a high percentage of copper to superconductor.
The cryostat has a length of 1900mm nominal and a height with support frame of 2824mm.
