European Synchrotron Radiation Facility - ESRF
The use of synchrotron radiation is highly beneficial for microtomography and radiography experiments due to the potential for short exposure times and increased contrast. Especially the use of partially coherent illumination allows for exploiting X-ray phase contrast in a routine manner, i.e. a method which can be combined with complex sample environments [1].
This presentation shall give a brief overview about the experimental capabilities at beamline ID19 of The European Synchrotron (ESRF) [2].
Beamline ID19 of the ESRF operates experimental facilities located 150 m downstream of the source: the long distance suppresses the influence of the finite sources size on the image formation and hence,
allows one to exploit propagation-based phase contrast. Frequently, polychromatic configurations are applied as the increased bandwidth leads to drastically reduced exposure times, down to the nanosecond regime for selected applications [3].
Fast tomography and ultra-high speed radiography are frequently coupled at beamline ID19 with sample environments. Besides classical tomography furnaces and a cold cell recent installations include different kinds of presses for uni-axial and tri-axial load, dynamic compression installation such as a gas gun, a Split-Hopkinson pressure bar and pulsed laser as well as dedicated rigs for the studying battery abuse testing and additive manufacturing in situ.
