Beamtime at GSECARS, Sector 13
GSECARS provides earth, environmental and planetary scientists with access to the high-brilliance hard x-rays from the Advanced Photon Source (APS), a third-generation synchrotron light source at Argonne National Laboratory. GSECARS staff work with prospective users to help them submit beam time proposals, to prepare samples before they arrive, to collect their data, and to analyze the data and prepare it for publication after they leave the facility.
All the available beam time at GSECARS is open to the scientific community on the basis of peer-reviewed beam time proposals to the APS General User Program.

Proposals are peer reviewed and rated by a technique specific Proposal Review Panel (PRP). Beamtime is awarded based on score and feasibility. It is suggested that a user select more than one beamline when submitting a proposal to increase the chances of receiving beamtime. Proposals expire in two years or when the number of PRP recommended shifts has been used, whichever comes first.
GSECARS recommends that any potential users contact the beamline scientist in their field to discuss their proposal prior to submitting the proposal.
A User Agreement, signed by a user’s home institution, is required before any experiments can be run at the APS or at any of Argonne’s user facilities.
