The neutron or x-ray storage ring/facility. Effective distance from sample Distance as seen by radiation from sample. This number should be negative to signify that it is upstream of the sample. Name of source short name for source, perhaps the acronym type of radiation source (pick one from the enumerated list and spell exactly) type of radiation probe (pick one from the enumerated list and spell exactly) Source power Source emittance (nm-rad) in X (horizontal) direction. Source emittance (nm-rad) in Y (horizontal) direction. particle beam size in x particle beam size in y Source intensity/area (example: s-1 cm-2) Source energy. For storage rings, this would be the particle beam energy. For X-ray tubes, this would be the excitation voltage. Accelerator, X-ray tube, or storage ring current Accelerator voltage Frequency of pulsed source Period of pulsed source Pulsed source target material any source/facility related messages/events that occurred during the experiment For storage rings, description of the bunch pattern. This is useful to describe irregular bunch patterns. name of the bunch pattern For storage rings, the number of bunches in use. For storage rings, temporal length of the bunch For storage rings, time between bunches temporal width of source pulse source pulse shape source operating mode for storage rings for storage rings Is the synchrotron operating in top_up mode? For storage rings, the current at the end of the most recent injection. date and time of the most recent injection. "Engineering" location of source The wavelength or energy distribution of the source
