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.
GSECARS congratulates Dr. Vitali Prakapenka on his award of the 2026 Gopal K. Shenoy Excellence in Beamline Science Award!
