CT-ALPHA nanotube
CT-system for resolutions down to 150 nm
The CT-ALPHA nanotube provides a unique solution for high-resolution measurements far ahead of established industrial micro CT scanners by applying the latest developments from X-ray research.
Min. voxel sampling 50 nm- Spatial resolution of 150 nm
- Photon counting detector
- Variable field of view
- Automatic alignment
- State-of-the-art reconstruction
Easy-to-Handle, Forward-Thinking Nano CT
The system combines the latest state-of-the-art components for highest resolution. Our experience in both hardware and software design enables us to perfectly adapt systems to your individual needs. Besides using only high-precision components, we also develop state-of-the-art reconstruction algorithms.
One main component of the system is Excillum’s high performance X‑ray source NanoTube N3, an up to 160 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 degrees of freedom (DOFs). A separate manipulation (2 DOFs) system on top of the rotation stage is installed for automatically adjusting the sample position in the center of the rotation.

Easy to Use
Scanning in nanometer resolution has never been easier.
The control software supports the user in all matters.
A separate manipulation (2 DOFs) system on top of the high-precision air bearing rotation stage is installed for adjusting the sample position in the center of the rotation by an automated routine.
From setting the scan parameters to reconstructing the volume, the user is guided by an easy and cleaned-up graphical user interface.
High Stability: The Prerequisite for Outstanding Resolution
For highest resolution with up to 150 nm, typical measurement times are 4 – 8 hours. Lower resolutions for this instrument, which is still at the limit of others, can be done in 1 – 2 hours.
Modern laboratory technology available for industrial applications
The functional features of novel material systems are often based on their complex inner structures, which are not accessible by established non-destructive analysis methods.
The fabrication of microelectronics and micromechanics becomes more and more complex, packed and 3D. After decades of successful miniaturization, industry now produces structures too small for established process control, hindering further improvements. Moreover, biological investigations would require more detailed 3D information of hidden inner structures in order to understand the morphology of various organisms, but such samples often provide too low material contrast.
Hardware and Software Made for each other
The best hardware needs a great software program to run it and to help you get the best results out of your investment.
