ABSTRACT:
A mandrel for holding gradient coils in an instrument that measures nuclear magnetic resonance is fastened directly to the magnet of this instrument. It is shown that this arrangement can be used to reduce the output of noise while, at the same time, making it easy to adjust the position of the mandrel. The device comprises two sets of brackets fastened by their struts, on either side of the magnet, to the end rings of the magnet. Each bracket exerts a holding force on the mandrel.
