NE-CAT is accepting GUP proposals for the 2017-1 run cycle. Please choose 24-ID-C or 24-ID-E as your first choice to be scheduled with NE-CAT! The 24-ID-C beamline can deliver X-rays in the range of 6 to 21 keV or ~2.1 to 0.5 Å. This covers most of the popular elemental edges for phasing. This wide energy-range also makes the beamline well suited for ultra high-resolution data collection and soft X-ray sulfur SAD phasing. The beamline is equipped with an optional kappa goniometer for optimal alignment of crystals. A Pixel Array Detector (PAD), Pilatus-6MF, installed on the 24-ID-C beamline helps measure very weak Bragg reflection intensities due to its noise-less readout technology and also provides a very fast data collection capability in shutter-less data collection mode. The 24-ID-E beamline is a fixed energy microdiffraction beamline delivering X-rays at 12.66 keV, optimized for Se-SAD experiments. It is equipped with a CCD-based ADSC Quantum 315 detector. Both beamlines are equipped with state-of-the-art instrumentation to handle advanced data collection methods. MD2 microdiffractometers installed at both beamlines provide very clean beams from 5 microns to 100 microns in diameter and have exceptional sample visualization systems capable of visualizing micron-sized crystals with extreme clarity. Deadline Friday, October 28, 2016 for: - New General User Proposals (GUPs) - New Beam Time Requests for APS run 2017-1 (1/31/2017 - 4/24/2017) on existing active proposals - Partner user proposals (PUPs) - CAT Member Proposals - APS Beamline Staff Proposals - CAT Beamline Staff Proposals The GUP system (https://beam.aps.anl.gov/pls/apsweb/gup0005.start_page) will accept proposals and beam time requests until 11:59 pm (Chicago time) on October 28, 2016. However, User Office support will not be available after 5:00 pm that day. If you feel you may need help during the submission process, please create your proposal as early as possible.
