近年來，同步輻射光源已成為高能物理、材料科學和生物學等多個科學領域研究的基礎且重要的儀器設備。同步輻射設備是基於粒子加速器架構使用高頻共振腔來加速電子，用以提升電子動能接近光速。更採用高磁場強度之磁鐵導引電子沿著加速器圓環而運行，並由永久聚頻磁鐵構成之週期性磁極產生電子之加速度運動，繼而發生同步輻射光源。同步輻射光源可應用於研究物質在原子和分子尺度之性質，近年來光源技術更是快速發展，世界各地陸續興建亮度更強的設備，以推動同步輻射光源之相關科學研究，加強推動科學新發現及創新技術力度。地理位置在台灣新竹的國家同步輻射研究中心（NSRRC），建造及操作台灣唯一的光子源（TPS）電子加速器，可提供高亮度之同步輻射光源於相關領域的基礎科學研究。針對高輝度及高準直性之X光源，必須使用液態氦和液態氮等超低溫流體維持超導高頻腔及低溫永磁插件磁鐵之運轉，其中超低溫技術之設計分析及運轉是重要之研究議題。本論文將針對低漏熱多內管型超低溫傳輸管路及低溫永磁聚頻插件磁鐵的液氮冷卻系統進行設計及分析，再針對液態氮冷卻之氦氣純化系統及各低溫元件進行基礎性研究，再根據結果進行設計分析製造及驗證。本論文之研究目的是提高低溫系統的效率及可靠度，達成同步輻射加速器所中裝置設備之高效率及高穩定之運轉目標，最後達成多內管型超低溫傳輸器長度及熱損降低達20%，並且在氦氣純化系統之研究初步成果節省成本約30%。綜上所述，本論文產出之超低溫技術及元件可裝設在台灣同步輻射光子源，預期在科學研究上提供更亮眼的貢獻。

In recent years, synchrotron light sources have become a fundamental and important tool and instrument for researchers in various scientific fields, such as high-energy physics, materials science, and biology etc. The synchrotron uses ultra-powerful magnets and RF resonant cavities to accelerate charged particles, such as electrons and protons, to approximate the speed of light. As the particles travel around the accelerator ring, they can emit synchrotron radiation in the band of X-rays, so that the properties of materials at the atomic and molecular scale could be measured and observed. The technology of synchrotron light sources has progressed rapidly on the construction of stronger and larger sources around the world. Many countries are now expending heavily in synchrotron research due to the consensus of the potential of expediting scientific discovery and technological innovation. In Taiwan, the National Synchrotron Radiation Research Center (NSRRC) has established a synchrotron light source, namely the Taiwan Photon Source (TPS), provides high-brilliance X-ray radiation for some prominent scientific applications. To operate the TPS in the maximal efficiency and performance, cryogenic refrigerants, mainly liquid helium and liquid nitrogen, are used to cool the superconducting cavities and magnets so that the superconducting state is maintained. Therefore, cryogenic technology is critical and essential for the daily operation of the TPS as well as other facilities in the light source. In this thesis, the design and analysis of low heat-loss multi-channel transfer line in cryogenic cooling system for Undulator is conducted. And, the helium purification vessel using liquid nitrogen cooling method is also investigated. The objective is to improve the efficiency and reliability of cryogenic systems used in the high performance TPS. The results are prominent to contributions in the scientific researches by synchrotron light source.
