“…Modern synchrotron sources can provide brilliant, high energy x-ray beams, which permit the fast acquisition of tomograms of millimetre thick highly absorbing metallic samples. Due to the short acquisition time of less than a minute per tomogram, tomography experiments during in-situ HTs have recently become possible at the ID15A beamline at the European Synchrotron Radiation Facility (ESRF) [4].…”

The formation of voids during the reaction heat treatment of internal tin Nb3Sn strands degrades the physical superconductor properties. The authors describe three void growth mechanisms on the basis of combined synchrotron microtomography and x-ray diffraction results obtained during in situ heating cycles. Initially, void growth is driven by a reduction of void surface area. The main void volume increase is caused by density changes during the formation of Cu3Sn in the strand. Long duration temperature ramps and isothermal holding steps neither reduce the void volume nor improve the chemical strand homogeneity prior to the superconducting A15 phase nucleation and growth.

“…Around the year 2005 (Lambert et al, 2007) the scan time for a single tomographic volume was of the order of 10 min at a spatial resolution of 5-10 mm. Already then, it was, however, demonstrated that it was possible to acquire a tomogram in less than a minute (Di Michiel et al, 2005;Lambert et al, 2010), and today 20 tomographic scans may be acquired within 1 second (Mokso et al, 2013;dos Santos Rolo et al, 2014;Maire et al, 2016). With such an acquisition speed, a new set of challenges arose.…”

Owing to recent developments in CMOS technology, it is now possible to exploit tomographic microscopy at third-generation synchrotron facilities with unprecedented speeds. Despite this rapid technical progress, one crucial limitation for the investigation of realistic dynamic systems has remained: a generally short total acquisition time at high frame rates due to the limited internal memory of available detectors. To address and solve this shortcoming, a new detection and readout system, coined GigaFRoST, has been developed based on a commercial CMOS sensor, acquiring and streaming data continuously at 7.7 GB s À1 directly to a dedicated backend server. This architecture allows for dynamic data pre-processing as well as data reduction, an increasingly indispensable step considering the vast amounts of data acquired in typical fast tomographic experiments at synchrotron beamlines (up to several tens of TByte per day of raw data).

“…Ultra-fast radiography has been demonstrated at various beamlines [1,2,3,4] and a number of exciting applications has been successfully addressed [5]. Nevertheless the extreme demand on the mechanics, synchronisation and the detector prevents a straight-forward transition from 2D towards 3D ultra-fast imaging.…”

The penetrating power of X-rays coupled with the high flux of 3rd generation synchrotron sources makes X-ray tomography to excel among fast imaging methods . To exploit this asset of synchrotron sources is the motivation for setting up an ultra-fast tomography endstation at the TOMCAT beamline. The state of the art instruments at synchrotron sources offer routinely a temporal resolution of tens of seconds in tomography. For a number of applications, for example biomedical studies, the relevant time scales (breathing, heartbeat) are rather in the range of 0.5-2 seconds. To overcome motion artifacts when imaging such systems a new ultra-fast tomographic data acquisition scheme is being developed at the TOMCAT beamline. We can acquire a full set of projections at sub-second timescale in monochromatic or white-beam configuration. We present a feasibility study with the ultimate aim to achieve sub-second temporal resolution in 3D without significant deterioration of the spatial resolution. Abstract.

For the first time, the 3D dynamics of the very early stages of a quickly aging liquid foam can be visualised with high quality and sufficiently large field of view.
