Dear all, Hereby I would like to invite the submission of Long-Term Projects (LTP) and Block Allocation Group (BAG) proposals for DESY beamline P11 at the PETRA III synchrotron in Hamburg.
The call is open until Monday, 15 July 2019 (inclusive; CEST/UTC+2) and relates to beamtime to be allocated during the period 2020 (first half) - 2021 (second half). Detailed information, preparation guidelines and templates for LTP and BAG proposals are provided here: https://photon-science.desy.de/users_area/user_guide/select_the_proposal_type 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 - 26 keV • Full SAD/MAD capability • High-precision single axis goniostat • Fast data collection via Pilatus 6M detector (25 Hz frame rate, 154 – 2000 mm sample-to-detector distance) • 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 • S2 level laboratory 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, Anja Burkhardt ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=CCP4BB&A=1
