Some photos from our calibration runs in Feb. 1998 and Sept. 1998. These took place in the CRyogenic Integration Facility (CRIF) at GSFC, and used 3 sources:

• Double-Crystal Monochromator (DCM), which produces monochromatic (single-energy) X-rays by using a pair of crystals. It was used for energies of 1000 to 10000 eV.
• Surface-Normal Rotation monochromator (SNR). This produces beams of low-energy (<1000 eV) X-rays with an extremely small spread in energy.
• Continuum source. This produces X-rays over a wide range of energies.
