NEWS FROM THE BEAMLINES

ID26
The hard X-ray emission
spectrometer has been upgraded
from a single-element photon-
counting to a Pilatus 100 k pixel
detector while maintaining on-the-
fly data collection. Alignment of
the 5 analyser crystals is now
considerably faster, and the larger
surface allows for separation of
the crystal foci if required.
ID23, ID29, ID30
The High-Pressure laboratory for
Macromolecular crystallography HPMX is
continuously expanding its offer of gas
pressure systems available to the ESRFs
large MX community In addition to the already
wellestablished pressure cells for noble
gases mainly He Ar Kr and molecular
oxygen to produce gas derivatives of
macromolecules recent developments
embrace pressure cells dedicated to the
introduction of CO
2
and CH
4
into
macromolecules The presence of CO
2
in
macromolecules can also be checked using
the Raman setup recently installed on ID30B

EWOKS
Ewoks the ESRF Workflow System is having a large impact being implemented at over 25
beamlines Ewoks supports fully automated workflows but can also be used interactively
through a graphical interface either from a local installation or as a web service Partly
funded by STREAMLINE Ewoks is more than just an automation tool as it allows data
processing to be more scientific reproducible and FAIR traceable It contains the
knowledge of dataanalysis experts in different fields using a variety of scientific algorithms
and tools and therefore allows nonexperts to use it For more information go to ewoksesrffr
CM01
Cryo-electron tomography (cryo-ET)
is an advanced imaging technique
allowing the visualisation and study of
3D structures of biomolecules within
their native environments at near-
atomic resolution. As of June this year,
CM01 has been offering cryo-ET, and
it has already proven successful. The
technique is available through the
Rolling Access system and is also
now integrated in the Solution-tO-
Structure SOS pipeline for non
cellular samples See esrffrCM01
for more details
ID19
Microtomography is available for fast access at the two
tomography set-ups, both integrated in the robotic sample-
changer hardware. For high resolution, pixel sizes of 0.6 µm
(10x/0.3NA) and 0.3µm (20x/0.4NA) are available (photon
energies of 19 keV, 26 keV and 35 keV). For medium resolution,
pixel sizes of 1.2 µm (5x/0.14NA) and 2.2 µm / 3.1 µm and
6.4 µm (3x, 2.1x, 1x Hasselblad) are offered (again, 19 keV,
26 keV and 35 keV as well as pink wiggler configurations).
Scientists mail in their samples and use a sample-
changer robot and remote desktop to carry
out the scans. Please contact the
beamline staff for more information.

A unique new end-station (left) provides
combined XRD-PDF with multi-edge XAS
measurements. The optics and end-station
work seamlessly together and switch
automatically between configurations,
allowing the acquisition of high-quality
and highly complementary information
under relevant working conditions in a
single experiment. The detection systems
include a CdTe Pilatus 2M, 16 pre-filled
ion chambers and several fluorescence
detectors. Dedicated ancillary equipment
is available for e.g. heterogeneous catalytic
and battery/electrochemistry experiments.
