Neutron tomography of pistons at IMAT – ISIS Neutron and Muon Source

A team of scientists from Finden Ltd (Dr Stephen Price, Dr Simon Jacques and Prof Andrew Beale) in collaboration with Infineum UK Ltd (Dr Nathan Hollingsworth, Dr Matthew Irving) have used IMAT to help understand where and how coking occurs on engine components. This understanding will help develop more durable, fuel efficient lubricants.​​ Read the […]

Dr. Antony Vamvakeros webinar on X-ray diffraction computed tomography July 21 – available to watch online

Synchrotron X-ray diffraction computed tomography (XRD-CT) is a marriage between powder diffraction and computed tomography using a “pencil” beam approach. The spatially-resolved signals obtained with XRD-CT can reveal information that would otherwise be lost in bulk measurements, which opens up new possibilities in functional material characterization. In this webinar, our research scientist Dr. Antony Vamvakeros […]
