Abstract
Apparatuses and methods for removing caps, such as NMR rotor caps. The apparatuses and methods may permit caps to be removed in a manner that minimizes damage to equipment and instruments. Microwave waveguides that may include an elongated waveguide, a spline horn, and a slotted waveguide. Analytical instruments that include the waveguides.
Claims16
A microwave guide comprising:
- a slotted waveguide comprising a metallic tube having a first end and a second end, wherein the metallic tube defines a plurality of slots in a surface of the metallic tube;
- a spline horn coupled to the first end of the slotted waveguide;
- and
- an elongated waveguide coupled the spline horn, the elongated waveguide comprising a tube having a substantially smooth inner surface, and wherein the elongated waveguide has an inner diameter configured to correspond to an incoming microwave beam generated by a separate microwave source and a quasi-optical transport table;
- wherein the spline horn is configured to focus a diameter of a beam of electromagnetic radiation from the elongated waveguide down to an internal diameter of the slotted waveguide.
