by Nancy Lazarz 23 Feb '21

23 Feb '21

[cid:image003.png@01D6A796.B18F9B80] Deadline for APS Proposals and Beam Time Requests Cycle 2021-2 Friday, March 5, 2021, 11:59 PM Chicago time New General User Proposals (GUPs) New Beam Time Requests (BTRs) on existing active proposals. ** Please note the following information: At this moment, current APS guidance for the 2021-2 run mandates that external non-ANL users will not be allowed on-site. Based on this current policy, GSECARS is only scheduling users that can mail-in samples, with partial or full remote access to control selected beamline computers to perform experiments in-close collaboration with GSECARS beamline staff. For the latest information regarding allowed activities at the APS, please see: https://www.aps.anl.gov/Users-Information/Updates/APS-General-User-Programs…<https://anl.us17.list-manage.com/track/click?u=cf3ed56636b3937a7799bf9d3&id…> The GUP system will accept proposals and beam time requests until 11:59 pm (Chicago time) on March 5, 2021.

Virtual workshop announcement “Compact Synchrotron Sources and New X-ray Science Opportunities” March 4-5, 2021

22 Feb '21

Aloha GSECARS Users, You are cordially invited to participate in a virtual workshop “Compact Synchrotron Sources and New X-ray Science Opportunities”, which will take place on March 4-5, 2021 via Zoom. Conventional synchrotrons are large-scale (typically hundreds of meter radius storage ring) facilities and cost close to a billion dollars to build and tens to hundreds of million yearly to operate. Synchrotron X-ray radiation is very intense and has unique properties that make it attractive for cutting-edge research in disciplines ranging from materials science to medicine. Over the last several decades, synchrotron experiment played a pivotal role in furthering mineralogy, petrology and mineral physics. They allow real-time in situ observations of chemical reactions and physical processes, determination of crystal structures of complex solids, liquids, and protein biomolecules, and imaging of 3-dimensional objects with resolution better than 1 micrometer. Between 1990 and 2020 as many as 10 Nobel prizes have been awarded in chemistry and physics for synchrotron-related research. Over the last decade, lab-based compact synchrotron devices have been developed, and some are now available as commercial turn-key instruments, offering many of the advantages of the large-scale facilities, though their usage thus far has been limited mainly to industrial labs and few universities outside the USA. This workshop is related to an ongoing effort to develop the Hawaiian Center for Compact Advanced Synchrotron Technology Innovation and Development (HI-COAST-TIDE) and aims to review existing compact-synchrotron source technology solutions and experience from ongoing projects of this type. It will also showcase diverse examples of user science that can be conducted at compact synchrotron facilities, and offer an introduction to experimental techniques such as In Situ X-ray Diffraction, X-ray Fluorescence and Absorption Spectroscopy, Computed X-ray Tomography and Phase Contrast Imaging, as well as Small Angle X-ray Scattering. The workshop will feature about 15 30-min-long presentations from leading X-ray science experts around the world and will target applications in chemistry, physics, materials science, geology, planetary science, biology, biophysics and medical research. If you already are a synchrotron user, we hope to show you if any of your research could be carried out efficiently at compact synchrotrons. If you have not used synchrotron X-ray techniques before, the workshop presentations should help you decide if becoming a home-synchrotron user could enhance your research and help addressing key science questions you are studying. The website of the workshop, with a schedule of talks and information about the speakers can be found here: https://sites.google.com/hawaii.edu/compact-synchrotron-workshop Pre-registration is required, and registration link is posted on the workshop website. We hope to see you all virtually at the workshop! Mahalo, Przemek Dera
