Nuclear spin resonance apparatus with a regulating unit for matching or adjusting the resonator
Abstract
Die Erfindung betrifft einen Stellantrieb für die Änderung der Resonanzfrequenz bei einem Kernspinresonanzgerät. Dieser Stellantrieb enthält eine dem Hauptmagnetfeld des Kernspinresonanzgerätes ausgesetzte Spule, die an einen Stromimpulsgeber angeschlossen wird und durch die Stromimpulse aus ihrer Ruhelage ausgelenkt wird. Die hin- und hergehende Bewegung der Spule wird durch ein Schrittwerk in eine schrittweise Dreh- oder Schubbewegung umgesetzt.
