Dear all, We are happy to inform you that the Call for Regular Proposals for PETRA III beamline P11 is now open.
This call relates to beamtime during July-December 2020. The deadline for PETRA III proposal submission is -------------------------------------------------------------------------- 2 March 2020 until midnight local Hamburg time (UTC+1) -------------------------------------------------------------------------- Preparation guidelines and templates for the proposals can be found here: https://photon-science.desy.de/users_area/user_guide/write_a_proposal/ Please make sure that the latest template is used for your proposal. All proposals have to be submitted via https://door.desy.de If you have suggestions, questions or encounter problems related to DOOR, please contact d...@desy.de Beamline P11 is dedicated to structural investigations of biological samples from atomic to micrometer length scales and currently provides two experimental endstations: an X-ray microscope (under construction) and a crystallography experiment which is in user operation since 2013. Specific features of the P11 crystallography endstation: • High photon flux (1.3 × 10^13 ph/s at 12 keV) at the sample position • Broad energy range from 5.5 - 28 keV • Full SAD/MAD capability • High-precision single axis goniostat • Fast data collection, currently via Pilatus 6M detector (25 Hz frame rate, 154 – 2000 mm sample-to-detector distance), from March 2020 on via Eiger2 16M detector (133 Hz frame rate) • Fast automatic sample changer (20 s) with uni-puck compatibility and 368 sample storage capacity • Cryo-shutter for crystal annealing • Beam size tunability from 4 × 9 µm² (microfocus) to 300 × 300 µm² (flat beam) within a minute • Microbeam capability (4 × 9 µm² focal spot with 1.3 × 10^13 ph/s photon flux and 1 × 1 µm² with 2 × 10^11 ph/s) • Serial synchrotron crystallography using liquid sample delivery like (tape-drive setup) and fixed targets (microporous Si-chips) • Parallel beam option for large unit cell systems • Data collection via Python-based GUI • Automated data processing with XDSAPP • 40 core workgroup server for fast data processing • Wet lab for sample preparation For detailed information about our experimental setup please visit our homepage http://photon-science.desy.de/facilities/petra_iii/beamlines/p11_bio_imaging_and_diffraction On behalf of the P11 team, Johanna Johanna Hakanpää, PhD Scientist, Beamline P11 (PETRA III) Deutsches Elektronen-Synchrotron DESY Notkestrasse 85 22607 Hamburg Germany Phone: +49 40 8998 5756 Email: johanna.hakan...@desy.de ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=CCP4BB&A=1
