CALL FOR PROPOSALS

Research time allocated through the General User mechanism is via competitive peer review emphasizing the excellence of science where there is intent to publish scientific results. A call for proposals is issued twice per year for experimental beam time. View participating beamlines

Proposal submission deadline is 12:00 noon CST.

Please note that the installation of new infrastructure is planned for spring 2017, which will reduce the number of available shifts. View Cycle 25 schedule. Due to the reduced number of shifts available in Cycle 25, please be advised that we are expecting the next round of General User allocation to be more competitive than normal.

Apply NOW for beamtime.
