Norwegian Centre for Nanoscale X-ray Tomography (NEXT)
The Norwegian Centre for Nanoscale X-ray Tomography (NEXT) is hosted by the X-ray Physics group at the Department of Physics, NTNU.
The NEXT facility consists of 5 instruments, of which 2 are set up for X-ray imaging experiments and thus relevant for EXCITE.
The following equipment is relevant to EXCITE:
Nikon HT225 CT scanner: The CT scanner operates with attenuation contrast, and is versatile operating with samples from a few mm, with nominal resolution ~1-2 microns, up to samples that are 10-15 cm diameter. The setup is equipped with a robust sample stage that can take loads up to 50 kg, allowing for operations with complex sample environments. At present, the lab offers access to a Deben CT5000 tensile/compression rig for in situ CT experiments under mechanical loads.
Custom-built X-radiography facility: The setup is designed for in situ imaging of evolving microstructures/phase fronts in thin radiographic cells. The system consists of a VISCOM XT9100 microfocus source (Mo, Ag or Cu), and a Vosskuhler CCD-camera, equipped with a SCINT-X pixeled scintillator, optimized for 17 keV radiation. The nominal performance characteristics of the setup is about 4-micron spatial resolution with frame rates up to 6 per second.
