Abstract

A prototype of the 325-MHz niobium half-wave coaxial resonator (\(\beta = 0.21\)) 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 \({{Q}_{0}} = (3.5 \pm 0.1) \times {{10}^{8}}\) at input powers of up to +20 dBm.

低微波场振幅下 325 兆赫半波超导谐振器的特性表征

开发、制造并在低微波场振幅下测试了 325-MHz 铌半波同轴谐振器（\(\beta = 0.21\)）的原型。利用一个高度稳定的射频（RF）发生器和功率探测器，研究了原型在超导状态下的连续波和阻尼状态下的电磁特性。谐振器在超导状态下的响应实验数据用于计算其最重要的特性--固有 Q 值和加速场。在输入功率高达 +20 dBm 时，原型的实验测量 Q 值是（{{Q}_{0}} = (3.5 \pm 0.1) \times {{10}^{8}}）。
