摘要

台灣光子源為國家同步輻射研究中心（National Synchrotron Radiation Research Center, NSRRC）建造的第二座同步輻射加速器，加速器的能量為3 GeV、電流強度500 mA，周長518公尺。高熱能狹縫吸收器（High Thermal Load Slit Absorber）位於加速器的前端區，目的是當加速器所產生的同步輻射光進入光束線（Beamline）之前，能減少光束的散射產生與限制通過的熱負載。本文利用有線元素分析法（Finite Element Analysis）與鎢片（Tungsten Blade）之設計，以模擬分析鎢片經同步輻射光照射後所產生之熱應力變化情形，此外，文中也將敘述鎢片設計製造與檢測之過程。

A third generation synchrotron accelerator called Taiwan Photon Source (TPS) in National Synchrotron Radiation Research Center (NSRRC) is under construction. It is a 3 GeV beam energy, 500 mA beam current accelerator machine with a 518 m circumference electron storage ring.Due to its high energy power, a high heat load slit is designed to scrap un-needed power at front end. The synchrotron radiation is trimmed through by Tungsten blades, which is mounted at outboard aperture of the slit. The Tungsten blades are used it as final confined aperture before beam passing through to beam line.The Tungsten blade is designed and analyzed by using Solidworks. Finite element analysis is carried out to simulate the temperature distribution due to its high thermal energy striking on the slit and the blades. In addition, the fabrication process and inspection result for tungsten blade are also presented in this paper.
