An Automated, High-Throughput System for GISAXS and GIWAXS Measurements

POSTER

Abstract

Grazing incidence small-angle X-ray scattering (GISAXS) and grazing incidence wide-angle X-ray scattering (GIWAXS) are important techniques for characterizing thin films.~ In order to meet rapidly increasing demand, the SAXSWAXS beamline at the Advanced Light Source (beamline 7.3.3) is implementing a fully automated, high-throughput system to conduct SAXS, GISAXS and GIWAXS measurements.~ An automated robot arm will transfer samples from a holding tray to a measurement stage.~ Intelligent software will align each sample in turn, and measure each according to user-defined specifications.~ Users will be able to mail in trays of samples, and will be able to monitor and control their experiments remotely.~ Data will be pipelined to the NERSC supercomputing facility, and will be available to users via a web portal that facilitates highly parallelized analysis.
