| dc.description.abstract | 在軸子(Axion)偵測實驗中，共振腔的品質因子(quality factor)、form factor和體積都很重要。大多數實驗通常使用帶有調頻桿的圓柱形腔體；然而，它們的體積受到實驗的目標共振頻率的限制。因此，我們需要研發一種具有良好性能的新型可調頻的共振腔體。在2020年，一種叫做圓錐殼共振腔體(conic-shell cavity)的新穎結構被提出。我模擬了圓錐殼共振腔體的特性，並透過測量兩個用鋁製成的樣品驗證了模擬的結果。使用這種設計，我們預期能將實驗對軸子-光子-光子耦合(axion-photon-photon coupling)的靈敏度提高2.6倍。 | zh_TW |
| dc.description.abstract | In the axion haloscope experiments, the quality factor, form factor, and volume of the resonator are important. Most experiments commonly use cylindrical cavities with a tuning rod; however, their volume is limited by the target resonant frequency. Thus, the development of a new frequency-tunable cavity with a good performance is needed. A novel structure called the conic-shell cavity was proposed in 2020. I simulated the characteristic of the conic-shell cavity and validated the results by measuring the performance of two prototypes fabricated with aluminum. Using this design, we expect to improve the experiment′s sensitivity to the axion-photon-photon coupling by a factor of 2.6. | en_US |
