Mail-in data collection at SPring-8 protein crystallography beamlines

Abstract

A mail-in data collection system makes it possible for beamline users to collect diffraction data without visiting a synchrotron facility. In the mail-in data collection system at SPring-8, users pack crystals into sample trays and send the trays to SPring-8 via a courier service as the first step. Next, the user specifies measurement conditions and checks the diffraction images via the Internet. The user can also collect diffraction data using an automated sample changer robot and beamline control software. For distant users there is a newly developed data management system, D-Cha. D-Cha provides a graphical user interface that enables the user to specify the experimental conditions for samples and to check and download the diffraction images using a web browser. This system is now in routine operation and is contributing to high-throughput beamline operation.
