Unique Features of the Osmic SAXS System(美國Osmic公司「高解析度小角度X光散射儀系統」之獨家特點)

1) Source(光源)

a. Microsource with confocal beam conditioning optic(具點收束型集光鏡之微X光源)

i. Provides monochromatic beam with intensity greater than focused radiation from existing rotating anodes with the exception of the Rigaku 007.(提供單一波長之光束，其光束強度高於，除了Rigaku007以外，現有之旋轉陽極靶所產生之聚焦輻射。)

ii. Operates at only 35 Watts and uses 110V VAC; no special power requirements needed(在35瓦的低功率下操作，並使用110伏特的交流電壓；不需特殊的功率。)

iii. Maintenance comparable to a conventional sealed tube source. (維修與傳統的密封管式的X光光源一樣簡單)

2) Camera(相機):

a. 3 pinhole geometry with user-exchangeable pinholes(具使用者可更換針孔之三針孔幾何系統)

i. Pinholes can be exchanged for variable flux/resolution without dismantling the entire system. (針孔可更換，以調整光束通率及解析度，不需拆除整個系統。)

ii. Pinholes can be moved out of the way to expose a large through-hole for sequential pinhole alignment. (針孔可移開自原有光徑，以便暴露一個大的貫通孔洞，以利連續之針孔對齊調整)

b. Open Platform design. (開放式平台設計)

i. The only system to offer additional scattering chambers (for different k-space ranges), simultaneous wide angle scattering using image plates, and a surface scattering/reflectivity stage, to name just a few unique options. (本系統獨一無二，提供了額外的散射室(以適用於不同的散射向量空間之範圍)，可同時以影像板測量廣角度散射，及提供測量表面散射/反射度的工作台，以上僅略舉數例。)

c. Large sample chamber with the optional ability to cover the incident and scattered beam paths with windows for samples in ambient or other non-vacuum environment.( 大型的樣品室，具含蓋入射及散射光束路徑的選擇能力，並開有視窗，以利常壓或非真空環境下的樣品測量。)

d. The sample changer drive mechanism is mounted outside the sample chamber to maximize the available space inside the chamber.( 樣品更換器驅動機制是安裝於樣品室之外，以使樣品室內的可用空間最大化。)

e. An x-ray photodiode is provided inside the sample chamber to be used for performance diagnostics and also fine tuning the alignment of the monochromator optic and the pinhole positions. (提供一個X射線光電二極管於樣品室內，用以診斷操作性能，及微調單光器光學系統是否對齊及針孔位置。)

f. Video display of the beam position on the sample simplifies the alignment of small samples. (影像顯示在樣品上的光束位置，簡化了小樣品的對齊調整。)

g. The beamstop is embedded with an x-ray sensitive photodiode for in-situ transmission measurement. (光束停止點嵌入了一個對X射線敏感之光電二極體，以提供即時穿透式的測量功能。)

3) Detector(偵測器) :

a. 2D Multiwire, gas-filled proportional type with(二維、多接線、充氣比例類型具有):

i. 120mm active diameter(120毫米之有效直徑。)

ii. Sub-microsecond time stamping for performing time resolved or periodic pump/probe experiments without waiting for data storage. (次微秒時間印記功能，以執行時間分離或週期性之泵送／探測實驗，不需等待資料儲存。)

Specimen Limitation

• 室溫測量條件下，固體樣品試片或薄膜尺寸 (size suggested for solid specimen or film under room temperature)：3 to 5 cm (length), 0.5 to 1 cm (width), and less than 1 to 2 mm (thickness). (The sample will be fixed on a sample rack with 42 holes (about 1 cm in diameter) on it using a 3M Scotch tape.)
• 變溫測量條件下(20-300C)，固體樣品試片或薄膜尺寸 (size suggested for solid specimen or film under varied temperature (20-300 C))：0.5 cm (length), 0.5 cm (width), and less than 1 to 2 mm (thickness). (The sample will be placed on a temperature-controlled liquid sample cell with sample size limitation mentioned above.)
• 固體粉末數量 (amount of powder): at least 0.5 to 1 cubic cm of the powder should be provided. (The sample will be put into a special quartz capillary (1 or 2 mm in OD, 0.1 mm in wall thickness, and 80 mm in length, which is imported from USA), and its one end will be sealed with a tape.)
• 固態樣品需無毒、無(或極低)揮發性、且無輻射性 (The sample should be free from poison, volatility, and radiation.)
• 室溫測量條件下(20C)，低黏度液體樣品溶液： at least 0.5 to 1 cubic cm of the low-viscosity liquid sample should be provided. (The sample will be put into a special quartz capillary (1 or 2 mm in OD, 0.1 mm in wall thickness, and 80 mm in length, which is imported from USA), and its one end will be sealed with epoxy.) Please be noted that the user should also provide at least 0.5 to 1 cubic cm of pure solvent sample for the X-ray scattering experiment in order to facilitate the background subtraction from the sample solution.
• 樣品若需沈積在基板上，基板的材質及厚度，不可讓X-ray對基板的吸收度高於90%以上，否則樣品將無法在穿透模式下測量。建議使用0.1mm厚度以下的矽晶片或石英玻璃片為佳。(If the sample has to be deposited on a substrate, the material and thickness of the substrate should not cause the degree of absorption of the incident X-ray greater than 90%. Otherwise, the sample will probably not be able to be measured its scattered intensity under the transmission mode of the test. It is suggested to use silicon wafer or quartz glass plate with a thickness less than 0.1 mm.)
