    Abstract: Attenuation of microwaves is reduced or prevented when vacuum windows are provided in microwave waveguides of a DNP-NMR probe. A DNP-NMR probe has an inner container and an outer container. The inner container has therein a sample tube containing a sample to which radicals are added. The outer container keeps a space between the outer container and the inner container in the outer container in a vacuum state. The outer container has an outer container waveguide that has a vacuum window at an inner end portion and guides microwaves. The inner container has a vacuum window facing the vacuum window of the outer container waveguide through vacuum, and guides microwaves transmitted from the outer container waveguide to the sample. The window-to-window distance between the vacuum window of the outer container and the vacuum window of the inner container is adjusted by means of adjustment bolts.

    Abstract: A direction shifting mechanism for changing a direction of a sample tube is installed on a path of the sample tube between a sample tube supporting unit for supporting, during an NMR measurement, the sample tube used for the NMR measurement and an insertion port through which the sample tube is inserted in and extracted from the sample tube supporting unit. The direction shifting mechanism has a shape which partially includes a form of an arc, and the shape is designed to cause the sample tube to change its direction in such a manner that the sample tube is turned toward the insertion port along the arc while being maintained in contact with at least two points on an inner wall of the direction shifting mechanism.

    Abstract: An angle adjustment mechanism has a block, a projecting piece, and a connection mechanism. The projecting piece is fixed to a stator. The connection mechanism has elongated holes provided in the block and a shaft member provided in the projecting piece. The shaft member is inserted in the elongated holes. During a tilt angle adjustment process, the shaft member is caused to move in a sliding motion in the elongated holes. During a cooling process, the shaft member is also caused to move in a sliding motion in the elongated holes.
