abstract = {A high-energy white synchrotron x-ray beam enables
penetration of relatively thick and highly absorbing
samples. At the P61A White Beam Engineering Materials
Science Beamline, operated by Helmholtz-Zentrum Hereon at
the PETRA III ring of the Deutsches Elektronen-Synchrotron
(DESY), a tailored x-ray radiography system has been
developed to perform in-situ x-ray imaging experiments at
high temporal resolution, taking advantage of the
unprecedented x-ray beam flux delivered by ten successive
damping wigglers. The imaging system is equipped with an
ultrahigh-speed camera (Phantom v2640) enabling acquisition
rates up to 25 kHz at maximal resolution and binned mode.
The camera is coupled with optical magnification (5x, 10x)
and focusing lenses to enable imaging with a pixel size of
1,35 micrometre. The scintillator screens are housed in a
special nitrogen gas cooling environment to withstand the
heat load induced by the beam, allowing spatial resolution
to be optimized down to few micrometres. We present the
current state of the system development, implementation and
first results of in situ investigations, especially of the
electron beam powder bed fusion (PBF-EB) process, where the
details of the mechanism of crack and pore formation during
processing of different powder materials, e.g. steels and
Ni-based alloys, is not yet known.},
