World record in time-resolved tomography

High-speed sample rotation table and laser heating system used for the time-resolved investigation of metal foams at the TOMCAT beamline of the Swis Light Source

Using a new high-speed sample rotation stage developed by the team at the Helmholtz Zentrum Berlin (HZB) in conjunction with the cutting-edge infrastructure available at TOMCAT for acquiring fast time-resolved tomography data, a team of researchers from both institutions was able to observe the evolution of a metal foam during its creation by laser heating with a record-breaking time-resolution of 208 tomographies per second. This marks a new milestone in the field, unlocking the possibiliy to investigate a host of fast dynamic processes that were previously inaccessible because they were simply too fast to be measured.

The results of these experiments have just been published in a new article in the journal Nature Communications on August 21, 2019.
