Abstract

We have performed a preliminary design for a persistent GHz NMR magnet at 23.5 T and 1.8 K operating conditions. In this paper we shall address the issues of realistic conductor selection, the coil design, the magnetic and mechanical analysis of the coil, and the required field uniformity. In addition, we shall describe the GHz magnet cryostat with a practical 1.8 K J-T refrigerator system. Finally the vibration isolation system and field shield design and its associated field harmonics will be analyzed
