    Abstract: A sample rotor is placed in a sample chamber inside an inner container. An air bearing type rotation mechanism blows a refrigerant gas (composed of a bearing gas and a driving gas) onto the sample rotor, to rotate the sample rotor and simultaneously cool the same. The refrigerant gas discharged from the air bearing type rotation mechanism is filled in an internal space (such as the sample chamber and a detection circuit chamber) of the inner container. An upper airtight chamber is formed between an outer container and the inner container. A lower airtight chamber is formed below a sealing bulkhead within a bottom unit. The upper and lower airtight chambers are in vacuum states to thereby function as vacuum insulation spaces for the internal space of the inner container.

    Abstract: A rotor contains a sample. A turbine cap is fitted into an opening of one end of the rotor, and a bottom cap is fitted into an opening of the other end of the rotor. A recess portion is formed in the turbine cap, and a recess portion is formed in the bottom cap. Insert members having a negative linear expansion coefficient are disposed in the recess portions.

    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: Provided are a polarizing agent that can selectively enhance NMR signals by the DNP-NMR method even in a reducing environment, and a method for selectively enhancing NMR signals. The present invention is a polarizing agent for use in the DNP-NMR method, the polarizing agent comprising nanodiamond particles, and the nanodiamond particles having a surface modified with a functional group capable of covalently binding to or interacting with proteins. The polarizing agent of the present invention can selectively enhance NMR signals by the DNP-NMR method even in a reducing environment.
