8. Single Undulator Module The single module datasets were were done for two purposes: 1) Determine the camera specifications needed to see undulator radiation from a single segment during commissioning. 14 GeV X Size (1 quadrant) = 60 mm, Y Size = 20 mm Energy resolution = .400 keV, Energy range = 0 to 24,690 keV 4 GeV X Size (1 quadrant) = 200 mm, Y Size = 60 mm Energy resolution = .040 keV, Energy range = 0 to 2,518 keV 2) Decide the practicalities of determining K differences in the undulator segments by measuring the x-ray spectra. X Size (1 quadrant) = 1 mm, Y Size = 1 mm Energy resolution = 1 eV, Energy range = 0 to 30,000 eV
