超高性能矽漂移探測器
FAST SDD® Ultra High Performance Silicon Drift Detector 型號:FAST SDDAmptek 最近在內部引入了矽晶片製造工藝並改進了此工藝。 他們生產出的探測器具有更低的雜訊、更低的洩漏電流、更好的電荷收集能力,並且探測器之間的一致性更好。 這使它成為目前性能最佳且真正尖端的矽漂移探測器。

產品概述
傳統的 SDD 在密封的 TO-8 封裝內使用了一個接面場效電晶體(JFET)以及一個外部前置放大器,而 FAST SDD 在 TO-8 封裝內使用了一個互補式金屬氧化物半導體(CMOS)前置放大器,並用金屬氧化物半導體場效電晶體(MOSFET)取代了 JFET。 這顯著降低了電容,提供了更低的串聯雜訊,並提高了短峰值時間時的解析度。 FAST SDD® 使用了相同的探測器,但帶有前置放大器,可在較短的峰值時間時提供更低的雜訊。 改善後的(更低)解析度可分離具有相近能量值以及峰可能重疊的螢光 X 射線,從而使用戶能夠更好地識別樣品中的所有元素。 較短的峰值時間也可顯著提高計數率; 更多計數可提供更好的統計數據。

Overview
Unlike our conventional SDDs which use a junction gate field-effect transistor (JFET) inside the hermetically sealed TO-8 package, along with an external preamplifier, the FAST SDD uses a complementary metal-oxide-semiconductor (CMOS) preamplifier inside the TO-8 package, and replaces the JFET with a metal-oxide-semiconductor field-effect transistor (MOSFET). This significantly reduces capacitance, providing much lower series noise and yielding improved resolution at very short peaking times. The FAST SDD® uses the same detector but with a preamplifier giving lower noise at short peaking times. Improved (lower) resolution enables isolation/separation of fluorescent X-rays with close energy values where peaks would otherwise overlap, permitting users better identification all of the elements in their sample(s). Short peaking times also yield significant improvements in count rates; more counts provide better statistics.
