CT-ALPHA nanotube結合了最新的最先進的組件，以實現最高的解析度！
其中最關鍵核心元件是Excillum公司的高性能X射線源NanoTube N2，這是一個高達110 kV的X射線管，採用最新的鎢-金剛石透射靶材技術，自動電子束聚焦和散光校正可確保在日常操作中始終如一地實現盡可能小的圓形光斑。
另一個重要零件就是來自DECTRIS的光子計數X射線探測器。這種檢測器由於零讀出雜訊和零暗電流而實現了最佳的訊號雜訊比。此外，雙源辨別能實現數位光譜調整。
兩個獨立的操縱系統允許非常精確的檢測器和樣品定位。一個高精度的空氣軸承旋轉載物臺提供了一個明確的樣品旋轉，安裝在一個具有3 DOFs的線性定位系統之上。在旋轉載物臺的頂部安裝了一個單獨的操縱（2 DOFs）系統，用於自動調整旋轉中心的樣品位置。

The system is combining the latest state-of-the-art components for highest resolution!
One main component of the system is Excillum’s high performance X ray source NanoTube N2, a up to 110 kV X ray tube with latest tungsten-diamond transmission target technology, automatic e beam focusing and astigmatism correction, ensuring that the smallest possible, truly round X ray spot is achieved.
The second main component is the photon counting X ray detector from DECTRIS. This detector enables an optimum signal-to-noise ratio due to zero readout noise and zero dark current. Moreover, dual energy discrimination enables digital spectrum adjustment.
Two separate manipulation systems allow a very precise detector and sample positioning. A high-precision air bearing rotary stage delivers a well-defined sample rotation, mounted on top of a linear position system with 3 DOFs. A separate manipulation (2 DOFs) system on top of the rotation stage is installed for automatic adjusting the sample position in the center of the rotation.
