An international research team at the Swiss Light Source (SLS) has set a new tomography world record using a rotary sample table developed at the HZB. With 208 three – dimensional tomographic X – ray images per second, they were able to document the dynamic processes involved in the foaming of liquid aluminium. The precision rotary sample table designed at the HZB rotates around its axis at several hundred revolutions per second with extreme precision. The HZB team headed Dr. Francisco Garcia – Moreno combined the rotary sample table with precision optics and achieved a world record of over 25 tomographic images per second using the BESSY II EDDI beam line in 2018. Now the team, together with the group headed by prof. Marco Stampanoni from the Paul Scherrer Institute ( PSI), has achieved a new world record at SLS. To accomplish this, they set up the rotary sample table together with improved optics, and used ultra – fast image acquisition and data transfer rates at the SLS/s TOMCAT instrument.” Over 200 tomogrpahic images per second can now be acquined – and that during measurement intervals of only several minutes,” says Garcia – Moreno.
