CT-ALPHA nanotube

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.
