KEY CONTACTSDATES FOR THE DIARY
USER CORNER
NEWS FROM THE BEAMLINES

ID23-1 At the Gemini macromolecular-crystallography beamline, the sample environment has been completely replaced. A new micro- diffractometer (MD2S from Arinax) has been installed, along with the new Eiger2-16M-CdTe detector. This refurbishment should lead to a tenfold acceleration of the data-collection times with an improved quality in measurements due to a reduction in radiation damage using higher radiation energies (up to 20 keV). As such, this beamline is ideal for very high-resolution diffraction experiments (up to 0.65 Å).
CM01 In a showcase of the potential of the ESRF s cryo-electron microscopy facility, the 2 Å barrier has now been surpassed with the structure of Apoferritin (see ESRFnews March 2021, p7), which could be resolved to a resolution of 1.67 Å using a K2 camera and an energy filter installed on the G3 Krios microscope. To enhance the throughput of data collection, CM01 will upgrade to a K3 camera in the coming months. This will allow for higher quality and faster data collections, so that users have the opportunity to collect sufficient data in a reduced experimental time. More details can be found on the CM01 website, esrf.fr/CM01.

ID22 The undulator source has changed to a 2.5 m-long in-vacuum U26, which will cover the 6 80 keV energy range, with more intensity above 60 keV compared with the previous arrangement. The bank of nine scintillation counters behind the multi- analyser stage has been replaced by an Eiger2 X CdTe 2M-W detector, which will improve angular resolution and high-angle statistical quality, once fully implemented. The control system for the gas capillary cell has been upgraded, enhancing the accuracy, stability, and speed of application of the pressure of non-corrosive gasses applied to samples for gas adsorption experiments in the pressure range 0 100 bar, e.g. the adsorption of CO2 in microporous zeolites or metal organic framework systems.
ID11 X-ray flux has risen ~20X thanks to the EBS. A new Dectris 4M-CdTe detector (image left) is on the nanofocus station and the 3DXRD instrument has a new marana SCMOS imaging detector for DCT experiments.
BM28 (XMaS) A Pilatus3 S 1M is available on the beamline for (GI)SAXS and (GI)WAXS measurements. It sits on a longer SAXS rail of about 2.6 m recently installed to extend the Q-range down to ~0.013 Å 1 corresponding to real space length scales of ~50 nm (image left).
E-travel The new ESRF e-travel software (SAP Concur) is now available for users receiving financial support for their experiments, giving them access to online travel booking and electronic submission of receipts and expense claims. More details at esrf.fr/etravel.
Data DOIs DOIs for experiment sessions are now minted automatically after the session and sent to the user team. The DOI reference is also available in the User Portal (SMIS) and the Data Portal (ICAT). More details at esrf.fr/ DOI.
