[cid:image003.png@01D6A796.B18F9B80] Deadline for APS Proposals and Beam Time Requests Cycle 2021-1 Friday, October 30, 2020, 11:59 PM Chicago time New General User Proposals (GUPs) New Beam Time Requests for 2020-1 on existing active proposals. ** Please note the following information: At this moment, current APS guidance for the 2021-1 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 (https://beam.aps.anl.gov/pls/apsweb/gup0005.start_page<https://anl.us17.list-manage.com/track/click?u=cf3ed56636b3937a7799bf9d3&id…>) will accept proposals and beam time requests until 11:59 pm (Chicago time) on October 30, 2020. *Start and end dates for this run are not yet finalized. The cycle will nominally run February-April.

Virtual hands-on tutorial on synchrotron computed microtomography
by Mark Rivers 17 Oct '20

17 Oct '20

Dear GSECARS Users, On October 29 and 30, Dr. Mark Rivers at GSECARS will host virtual hands-on tutorial sessions on synchrotron computed microtomography. Two identical tutorial sessions will be offered. We will use Zoom, and each session will last 4 hours (1-5pm CDT). Title: Virtual Hands-On Tutorial on Synchrotron Computed Microtomography Teacher: Mark Rivers rivers(a)cars.uchicago.edu<mailto:rivers@cars.uchicago.edu> Dates: October 29 and 30 Time: 1-5 PM CDT Number of participants: 12 each day, 24 total Background reading: Introduction to Computed Microtomography & Applications in Earth Science (https://cars.uchicago.edu/data/rivers/ClayMineralSociety/05-Rivers.pdf) Schedule 1:00 Introduction to beamline 1:20 Introduction to computed microtomography 1:40 Overview of data collection process 2:00 Break 2:10 Collect absorption and phase contrast tomography data on Doug Schmitt's Chicxulub samples 3:10 Break 3:20 Overview of tomography data reconstruction 3:40 Reconstruct the Chicxulub data 4:30 Discussion 5:00 End If you are interested, please contact Mark Rivers at rivers(a)cars.uchicago.edu<mailto:rivers@cars.uchicago.edu> with your preferred date. If the number of applicants exceeds 12 for one session, we will follow a "first come first serve" selection process.

AGU Town Hall: COMPRES-GSECARS Merger
by Consortium for Materials Properties Research in Earth Sciences 15 Oct '20

15 Oct '20

Save the Date: AGU Town Hall on COMPRES-GSECARS Merger, Dec. 7 In response to the Dear Colleague Letter released by NSF announcing its intention to unify all EAR supported synchrotron facilities into a single management structure (aka COMPRES-GSECARS merger), we will be holding an AGU Town Hall for the community to discuss possible paths forward. https://agu.confex.com/agu/fm20/meetingapp.cgi/Session/101435 The meeting will be held on Monday, 7 December 2020, at 10:30-11:30 (America/Los Angeles). We will be releasing an update in the near future with a final agenda. If you have any questions please contact: Carl Agee (agee(a)unm.edu<mailto:agee@unm.edu>) Mark Rivers (rivers(a)cars.uchicago.edu<mailto:rivers@cars.uchicago.edu>) Andrew Campbell (campbell(a)geosci.uchicago.edu<mailto:campbell@geosci.uchicago.edu>)

COMPRES Keynote Lecture Series: Joseph O'Rourke on Oct 22, 2020
by Consortium for Materials Properties Research in Earth Sciences 08 Oct '20

08 Oct '20

Please join us for the COMPRES Keynote Lecture Series with: Dr. Joseph O'Rourke Arizona State University on October 22, 2020 at 4pm EDT Zoom link: https://unm.zoom.us/j/92342893928?pwd=ZTdKQW1zZ0M3U0lERE1BUnRETHNDZz09 Talk title and abstract: Chemistry Controls Dynamos in Metallic Cores: A Tour of the Solar System and Beyond Magnetic fields provide unique windows into the deep interiors of planetary bodies and their evolution over deep time. Most worlds in our Solar System with radii >1,500 km and metallic (iron-rich) cores are known to have a dynamo today or had one in the past. Simple models assume that dynamos typically arise from thermal convection, which leads to a simple criterion for dynamo activity: the total heat flow across the core/mantle boundary must exceed that which is conducted upwards along the adiabatic temperature gradient in the core. However, chemical processes in metallic cores, including crystallization of an inner core and reactions with the basal mantle, can overpower thermal convection. In this lecture, we will tour the galaxy to see how chemistry may help or hinder a dynamo. We will start on Earth and then travel to our Moon and the other terrestrial planets (Mercury, Venus, and Mars). Next, we voyage out to Jupiter to explore why one Galilean satellite (Ganymede) has an active dynamo but not the others (especially Io and Europa). Finally, we leave our Solar System to speculate about the significance of future detections of magnetic fields at super-Earth (or super-Venus?) exoplanets. Ultimately, the general importance of chemical processes to dynamos highlights the need to understand key material properties across a highly multi-dimensional space of pressure, temperature, and composition.
