探測器陣列

XRA-700 是一種多通道 X 射線光譜系統，配備七個高性能 X 射線探測器和低雜訊前置放大器，以及具有電源和冷卻裝置的控制單元。 利用 Amptek 在 XRF 技術領域的豐富經驗和市場上最廣泛的探測器組合，XRA-700 可以配置七個相同的探測器，也可以配置各種探測器以滿足應用需求。

作為標準配置，該系統配置了 7 個 70 mm2 FAST SDD® 探測器，其它選項包括 : 

• 70 mm² FAST SDD，具有 C2 視窗（40 nm Si₃N₄），用於檢測低至 Be Kα 線的 X 射線。
• 1 mm厚的 70 mm2 FAST SDD 可在高能量下將固有效率提高 2 倍。
• CdTe 偵測器效率高達 150 keV。

產品特點

• 可配置 7 個相同的探測器，或任意組合探測器，以便針對特定測量更好地最佳化感測器。
• 與第三方多通道數位脈衝處理器相容。
• 如果玻璃窗破裂，只有一個探測器發生故障，其餘探測器會繼續正常運作，因此您可以繼續進行實驗。
• 獨特的設計，可以更快、更經濟地更換單一探測器。

The XRA-700 is a multichannel X-ray spectroscopy system, with seven high-performance X-ray detectors with low noise preamplifiers, plus the control unit with power supplies and cooling. Utilizing Amptek’s rich history in XRF technology, and broadest portfolio of available detectors on the market, the XRA-700 can be configured with seven of the same detectors, or with a variety of detectors to meet the needs of the application.

As standard, the system is configured with seven 70 mm2 FAST SDD® detectors, but other options include:

• 70 mm² FAST SDD with a C2 window (40 nm of Si₃N₄) for detecting X-rays down to the Be Kα line.
• 1 mm thick 70 mm2 FAST SDD for up to 2x better intrinsic efficiency at high energies.
• CdTe detectors with good efficiency up to 100 keV.

Benefits

• Can be configured with seven identical detectors, or for any combination of the detectors, to better optimize the sensors for a particular measurement.
• Compatible with third-party multi-channel digital pulse processors.
• In the event a window breaks, only 1 detector fails, the remaining detectors continue functioning as normal so you can keep running your experiment.
• Design allows for faster and more economical replacement of an individual detector.

Spectra Plots

High Rate Spectra  Typical spectra from a FAST SDD that shows excellent resolution at high count rates and low background noise, facilitating detection of the smallest concentrations of elements possible with XRF.	CdTe Spectra  Typical spectra from a CdTe detector that enables heavy element detection.

Attenuation Spectra Compound graph of different window transmission (C2 allows transmission of lightest elements) and detector stopping efficiency for all detector types available (regular FAST SDD, 1mm thick FAST SDD and 1mm thick CdTe).	1 mm Spectra  Compound spectra showing the benefits of the 1mm thick FAST SDD. Up to 2x the stopping power for elements >15keV, with no loss of performance for lighter elements compared to regular FAST SDD. Excellent for rare earth elements.
