Project Science: Bi-Spectrograms

A Catalog of Bi-Spectrograms from the XRCF Calibration

The following catalog of x-ray bi-spectrograms (in GIF format) were obtained using the RAS and either the HIREFS or DCM monochromator in conjunction with the FPC detector. They represent FPC pulse height spectra as functions of the monochromator wavelength (or energy) setting. The latter is varied monotonically while data is accumulated. These spectra provide qualitative information for use as as planning tools for calibration activities.

The HIREFS monochromator uses either the SA, SB, SC, or SX grating. The DCM monochromator uses either the TAP, Ge, aSi, or KDP crystal pair.
