CT Skanner_Ann Axelsson


Researchers in wood technology at Luleå University of Technology in Skellefteå has access to a unique CT-scanner combined with climate control. This allows for materials studies in situ in temperatures above 200 degrees.

In 2008, the old CT scanner at LTU in Skellefteå was replaced with a new equipment, funded by the Foundation Niels and Dorthi Troëdsson Research Fund and Sparbanksstifelsen, and a few years later the equipment was supplemented with a custom-built environmental chamber. With the upgraded equipment, you can study how the wood drying process continues and industry can thus better control the process to a high quality product.

In the research world, the CT scanner and environmental chamber is used to physically describe the drying process for wood but it is also possible to study other materials that are treated similarly to wood. The CT scanner has great significance for the future of the timber industry and reinforces the University's leading position both nationally and internationally in log scanning, drying, heat treatment, moisture dynamics, and other processes.

We have more than 20 years experience from CT-scanning of wood which means that we are world leading in this field. Our old CT-scanner has been worn out so a new one was installed in 2008. Luleå University of Technology has also developed an industrial X-ray LogScanner that now is used on about 15 sawmills throughout Europe. For this work Anders Grönlund, Johan Oja and Stig Grundberg were awarded the Schweighofer Prize in 2007.
