GSECARS
A national user facility for frontier research in the earth sciences using synchrotron radiation at the Advanced Photon Source, Argonne National Laboratory.
GSECARS provides earth scientists with access to the high-brilliance hard x-rays from this third-generation synchrotron light source. All principal synchrotron-based analytical techniques in demand by earth scientists are being brought to bear on earth science problems.
Users shipping to GSECARS, we are experiencing LONG delays in receiving international packages due to US Customs delays.
Please plan accordingly!

Latest Happenings at GSECARS
13 ID-D Table Upgrade
Unlocking a Sea Ice Secret
Prof. Rachel Obbard and her research group from Dartmouth College traveled to the Antarctic to collect samples of sea ice. Next stop: the GeoSoilEnviroCARS x-ray beamline at the Advanced Photon Source at Argonne National Laboratory in Illinois.
ANL Exemplary Student Research Program
GSECARS hosted three groups of local ESRP high school students at Sector 13 at the Advanced Photon Source. The students, with guidance from staff scientists Matt Newville and Tony Lanzirotti, used synchrotron radiation to perform experiments with topics ranging from the investigation of metals in dandelions to a microanalysis of canine hair to looking for biomarkers in fossils. The three groups will present posters at the APS User Meeting in May, 2013.
Using Python for Epics Channel Access
The PyEpics package provides low-level (C-like), procedural (caput/caget,…) and object-programmed interfaces for EPICS channel access. This allows for simple as well as sophisticated code development for beamline instrument control using Python.
