Abstract

In a superconducting magnet coil configuration, in particular for a high resolution analytical nuclear resonance (NMR) spectrometer, with a cryostat having extremely low heat losses (low loss), comprising at least one essentially cylindrical container (1) with a vertical cylinder axis (k), with a vertical cylindrical room temperature bore (3) and with at least one inner tank (4) for a cryogenic liquid in thermal contact with a superconducting magnet coil (2) enclosing the room temperature bore (3), for generating a vertically directed, extremely homogeneous and stable magnetic field of high field strength inside a measuring volume of the room temperature bore (3), the vertical axes (r) of the room temperature bore (3) and of the superconducting magnet coil (2) run parallel to and at a distance from the vertical cylinder axis (k) of at least one of the cylindrical cryostat containers (1). In this way, access to the room temperature bore (3) is considerably simplified.
