同步輻射光是二十世紀以來科技研究最重要的光源之一，研究人員藉由同步輻射光可從事物理、化學、生物、材料、化工、環保、能源、電子、微機械等基礎與應用科學研究。同步輻射光的原理是將電子束注入儲存環後，由環內一系列磁鐵導引偏轉並維持在軌道上，電子束能於每一圈的運行中在偏轉磁鐵切線方向放出同步輻射光。由於電子會因輻射而損失能量，因此環內裝置高頻共振腔來補充電子的能量。而當共振腔體承受預力及外界振動源時，會造成其結構的振動特性改變進而使內部電磁場共振頻率產生偏移，為確保光源品質，了解共振腔體自然頻率與模態並精確地調整電磁場的共振頻率是十分重要的。本文將以套裝軟體ANSYSÒ分析電磁場共振頻率分別為500MHz及1.5GHz之兩種低溫超導共振腔體自然頻率與模態;並分析腔體實際操作環境受預力的自然頻率與模態。在幾何參數方面，討論不同腔體厚度及兩端開口大小對於腔體自然頻率之影響。在實驗方面，將使用銅製1.5GHz腔體模型進行實驗，並與ANSYSÒ的分析結果比較。本文研究結果可供日後共振腔體振動控制之參考。
