| Abstract | TL99; 碳剥离膜作为剥离器的核心组成部件是医用重离子加速器的重要装置之一,研制出满足医用重离子加速器要求的碳剥离膜至关重要.采用交流弧光放电法完成了医用重离子加速器中碳剥离膜的研制,并用扫描电子显微镜和拉曼表征手段测试分析了碳剥离膜的薄膜特性.为了不影响已注入环中离子的正常运行,靶框设计为U型,靶边框较窄仅为2mm,碳剥离膜的有效面积为1 600 mm2(40 mm×40 mm).碳剥离膜的厚度为15 μg·cm-2,理论计算结果表明该碳剥离膜的厚度均匀性为97.65％.碳剥离膜具有一定的机械韧性,可以完成碳剥离膜的自动换膜过程,且在自动换膜过程中无破裂损伤.扫描电子显微镜观测结果显示:碳剥离膜的表面平整,内部结构致密.拉曼测试结果表明:位于1 580 cm-1附近的G峰明显强于位于1 300 cm-1附近的D峰,说明薄膜的石墨化程度较高;2 700 cm-1左右的2D峰较弱,说明石墨分子层数较多. |
