    Structured Review

    Magritek Ltd lc tuning circuit
    Expanded schematic of the <t>homebuilt</t> 9.81 GHz TE102 resonant microwave cavity. The screw holes and shim coils are not shown for clarity. Panel (A) shows the configuration for a fixed resonant frequency, suitable if the magnetic field can be varied. Panel (B) shows the changes required for a variable resonance frequency cavity, if hyperpolarization in a fixed magnetic field is desired. The variable-frequency short is placed inside the waveguide extension, which then replaces the fixed-frequency short present in (A). The rest of the pieces are unchanged. Panel (C) gives the dimensions for the cylindrical portion of the variable-frequency short. The ¼-32 threads on the cylindrical portion and the threaded hole in the attached plate allow for rotation of the cylindrical portion against the plate to adjust the position of the short inside the waveguide extension, thereby changing the length and frequency of the cavity.
