Technical specifications

 

The 9.4 Tesla/31 cm active-shield (AS) magnet is the first ultra-wide bore 9.4 Tesla horizontal bore magnet for biomedical imaging research in continental Europe. The picture shows the magnet in its final position, ramped to field and shimmed to 2.8ppm over 14cm dsv. The system is mainly used for rodent MR investigations. The operating console was provided by Varian Inc. (Palo Alto, CA).
