Each is documented individually in the readme, in chronological order. Data files are provided in three compressed folders (one for each experimental run). A .CSV file is also included for each experimental run, which gives file-specific parameters (e.g. beam position, energy, etc).This dataset consists of several hundreds of data files taken by the Focusing Optics X-ray Solar Imager (FOXSI) sounding rocket x-ray detectors during tests at the Advanced Light Source (ALS) at the Lawrence Berkeley National Laboratory. These tests involve illumination of the FOXSI semiconductor double-sided strip detectors with a fine, collimated beam at known X-ray energies produced by the ALS synchrotron. Some of the tests involve fine scans across the surface of the detectors, characterizing spatial dependence of detector performance, including at multiple locations within specific strips. The purpose of these experiments was to improve characterization of the detectors both before and after the flight of FOXSI-3. This characterization includes determining detector quantum efficiency, as well as measuring charge sharing between detector strips.Attribution-NonCommercial 3.0 United Statessemiconductor detectorsdetector testsdetector efficiencycharge sharingX-ray astronomysynchrotron beamlineDatasethttps://doi.org/10.13020/KKFH-5M05
