ID22 ID22 has installed a new detector arm (right), increasing the number of Si 111 crystals on its multi-analyser stage from 9 to 13 while maintaining the nominal 2˚ spacing between channels. This upgrade follows the installation in January of the Eiger2 X CdTe 2M-W detector, which is now the standard configuration for high-resolution powder diffraction. Future exploitation of the spatial resolution afforded by the detector will allow further improvements in angular resolution and counting efficiency. The arm can also be used without analyser crystals yielding higher counting efficiency, but with lower angular resolution.

ID19 DragonFly is a 3D rendering software used to produce images of tomographic data and is available on a dedicated high-performance computer for the users of ID19. It allows the visualisation of results during an experiment and is a powerful tool to optimise the acquisition strategy.
ID29 First monochromatic beam for the new ID29. The upgrade of ID29, which is part of the EBSL8 project, consists of the construction and commissioning of a new structural-biology beamline dedicated to time-resolved serial crystallography experiments. The new beamline is designed to fully thrive from the characteristics of the EBS machine and achieves spatial and temporal resolution that will open new perspectives for the study of time-dependent structural studies in biological macromolecules. The coming months will see the installation of the experimental station to welcome friendly users next spring.
Access to user data Access Control Lists (ACLs) are applied to the scientific data collected at the ESRF to ensure that only the proposers and users associated with a proposal can access the data, as well as the relevant beamline staff. More details can be found in the FAQ at tinyurl.com/ESRFACLs. These data are archived on tape and removed from disk 90 days after the end of the session this is then followed up by the closure of the NICE account if no new further session is ongoing. In parallel, raw data and metadata are catalogued and made accessible to the user team from the Data Portal (data.esrf.fr) for the beamlines implementing the data policy (esrf.fr/datapolicy). To share data with other collaborators, see tinyurl.com/ESRFdatashare.
ID26 The installation of a new gas distribution system (below) on beamline ID26 greatly facilitates the safe use of toxic and corrosive gases for experiments under in situ conditions. Both experimental hutches hosting the hard and tender X-ray spectrometer are supplied by the system.
BM18 The new EBS beamline BM18 will start user operation in September 2022 (proposal submission deadline, 1 March 2022). The big sample stage will not yet be installed for user experiments in 2022 due to pandemic-related delays, but a smaller stage (maximum 30 kg) will be available instead.
