Data Management at the Advanced Photon Source
Data are crucial to the scientific discoveries enabled by experiments performed at the APS. Presently the APS generates approximately 10 PB of raw experimental data per year from its sixty-six operating beamlines that house over 100 unique instruments. This data is generated as a part of over 6,000 annual experiments performed by over 5,500 facility users each year. Similar to other synchrotrons, the amount of data generated at the APS continues to quickly increase due to beamline advances, such as new measurement techniques, technological advances in detectors, high-throughput instrumentation, multi-modal instruments that can acquire several measurements in a single experiment, and advanced data processing algorithms. This trend is expected to continue in the future. The revolutionized high-energy synchrotron facility proposed in the APS-U project will increase brightness and coherence, leading to further increases in data rates. Successful management of data is of vital importance to the current and future scientific productivity of the APS.
