Several giant accelerator services employ superconducting niobium cavities for improved performance in comparison with metallic (copper) cavities. The loop-hole resonator (LGR) is made by cutting a narrow slit alongside the length of a conducting tube. If you enjoyed this article and you would like to obtain more facts regarding read the article kindly see the page. The slit has an effective capacitance and the bore of the resonator has an effective inductance. Subsequently, the LGR may be modeled as an RLC circuit and has a resonant frequency that is often between 200 MHz and 2 GHz. In the absence of radiation losses, the effective resistance of the LGR is set by the resistivity and electromagnetic skin depth of the conductor used to make the resonator.
