| 中文摘要 | 台灣光子源(TPS)分岔吸收器安裝於超高真空環境的儲存環內,分岔吸收器被高能量與高密度的同步輻射光照射,除了會產生熱變形外,表面會產生光子引發的釋氣,影響儲存環的真空度。為確保分岔吸收器的製造品質,於台灣光源(TLS)光束線BL19B進行光子引發釋氣實驗,探討分岔吸收器經由同步輻射光照射後之釋氣現象。本實驗設備需真空氣導的設計,使用真空氣導解析公式與Monte Carlo數值解的方式來計算並比較兩者的真空氣導值差異。分岔吸收器製造完成後,分別讀取於0.1Ah、1Ah及10Ah照光劑量之殘餘氣體分析資料。另將不同一支的分岔吸收器經臭氧水清洗後,照射同樣的照光劑量做釋氣實驗,比較兩者光子脫附產率。臭氧水清洗後之吸收器,於0.1Ah、1Ah及10Ah照光劑量時,相對於未經臭氧水清洗之分岔吸收器,其光子脫附產率低了7.7倍、5.2倍及1.9倍。殘餘氣體分析顯示臭氧水對於高分子量之碳氫化合物油氣有明顯的清潔效果。隨著照光劑量增加,有無臭氧水清潔過之兩分岔吸收器,光子引發釋氣現象逐漸一致,顯示臭氧水清潔效果於低照光劑量有較明顯的差異。 |
| 英文摘要 | The crotch absorber will be installed in the Ultra-High Vacuum of storage ring of Taiwan Photon Source (TPS). The high power and high density of synchrotron radiation irradiates the crotch absorber inducing not only the thermal deformation but also the photon-stimulated desorption (PSD) phenomena. For making sure of the quality of crotch absorber, the PSD of crotch absorber was studied by using synchrotron radiation at TLS BL19B. The experimental vacuum chamber need to calculate the vacuum conductance. Both the analytical formula and program of Monte Carlo simulator are used to compare the deviation of the vacuum conductance data.The PSD phenomena were compared with and without ozone cleaning. The photodesorption yield of ozone cleaning crotch absorber, at beam dose 0.1Ah, 1Ah and 10Ah, which were 7.7, 5.2 and 1.9 times relatively lower than without ozone cleaning crotch absorber. Residual gas analysis showed that the high mass hydrocarbon signal of ozone cleaning crotch absorber was lower than without ozone cleaning crotch absorber. As beam dose increasing, both of with and without ozone cleaning crotch absorbers had the same PSD phenomena gradually. The results showed that the better effect of ozone cleaning at lower beam dose. |
