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.
