Fig. 7From: X-ray microtomography and linear discriminant analysis enable detection of embolism-related acoustic emissionsExperimental setup of the Fraxinus excelsior L. tree in the environmental µCT (EMCT) scanner. The EMCT continuously rotates around the stationary tree without the risk for twisting and winding of sensor cables. The carbon fiber tube was designed to ensure stable and centered positioning of the tree during µCT scanning. The tree is equipped with two broadband point-contact AE sensors in a pvc spring-containing holder to continuously register AEs from the progressively dehydrating xylem (AE1, AE2), and a point dendrometer to continuously register xylem shrinkage. The red circle indicates an aluminum enclosed leaf used for pressure chamber measurements to determine xylem water potentialBack to article page
