KEY CONTACTSDATES FOR THE DIARY

NEWS FROM THE BEAMLINES

ID26 The tender X-ray spectrometer on ID26 is now available for user operation. The instrument covers emission energies down to the S Kα lines at 2310 eV (soon down to Al Kα at 1486 eV with quartz analysers). More information at www.esrf.fr/ID26.
ID30A-1 MASSIF-1 has recently been upgraded with an EMBL MD2s microdiffractometer and FLEX HCD sample changer (N.B.UNIPUCKS only with a capacity of 368 samples). With the brighter and smaller beam from the EBS upgrade, the beamline is now able to process samples much faster.

ID15B After a long and fruitful service, the MAR555 has been replaced by an EIGER 2, 9M, CdTe. Its nine million 75 x 75 µm pixels can each count up to 107 photons/sec. With the new detector comes a new beamline control software, BLISS.
BM20 (ROBL) Four new experimental stations are now available. The highly automated, high-throughput XAFS station provides EXAFS and conventional XANES of samples inside a glovebox at temperatures down to 10 K, at sub-p.p.m range sensitivity. The XES station provides high energy-resolution fluorescence detection (HERFD) for XANES, XES and RIXS, covering both actinide L and M edges together with other elements at 3 20 keV energies. The XRD-1 station delivers high- resolution powder diffraction, and surface-sensitive CTR and RAXR techniques. Finally, the XRD-2 station provides single-crystal diffraction, powder diffraction with high temporal resolution and X-ray tomography experiments, with a Pilatus 2M detector. CM01
The cryo-EM microscopy facility now proposes an extended service, the Solution-tO-Structure (SOS) pipeline, which opens up opportunities for ESRF users who have biochemically well- characterised samples but cannot pursue cryo-EM due to the lack of or inadequate EM infrastructure. Interested users should apply via rolling access, and proof of a pure and monodisperse sample will be required. More details can be found on the CM01 website. The SOS pipeline is a PSB collaboration between the ESRF and the IBS-EM platform.
SOM Group A new, versatile camera for the beamlines ID06-HXM, ID11, ID15A, ID19, ID22 and ID31 is available for high-speed imaging experiments. The camera should record 100,000 images per second at 600 × 400 pixels for durations of several seconds.
BM29 Along with a new in-vacuum detector, there is a new sample-delivery robot, two new in-vacuum sample environments to exploit the new source and to allow in-vacuum microfluidics, and a new beamline collection software suite, BSxCube3.
BM28 (XMaS) A restart in January after an entire rebuild of the beamline takes full advantage of the ESRF EBS upgrade. Material scientists can now exploit a 2.03 41 keV monochromatic beam in various complex sample environments and with numerous X-ray techniques.
ID32 Upgraded RIXS spectrometer optics and the beamline refocussing optics mean that the resolving power of the overall instrument has been improved. At the copper L3 edge (~932 eV) in low/medium/high-resolution modes, ~42 meV/~35 meV/~28 meV can now be achieved. Polarimetry measurements are now also possible with improved resolution (low-resolution mode). There are significant gains at higher photon energies; for example, ~45 meV and ~60 meV at the Ho and Yb M4 edges, respectively. These improvements also mean that lower energy-resolution measurements can be done with a higher flux than before the upgrade.
