Zusammenfassung: | A prototype of the 325-MHz niobium half-wave coaxial resonator (
) is developed, built, and tested at low microwave field amplitudes. Electromagnetic properties of the prototype in the superconducting state are investigated in the continuous wave regime and the damping regime using a highly stable radio-frequency (RF) generator and power detectors. The experimental data on the resonator’s response in the superconducting state are used to calculate its most important characteristics—the intrinsic
Q
value and the accelerating field. The experimentally measured
Q
value of the prototype is
at input powers of up to +20 dBm. |
