Multilayers

Measurement of reflectance from a depth-graded W/Si multilayer designed and fabricated for HEFT. Typical values for the interface width are 3.5–4 Å for this material combination. This particular sample was characterized up to 40 keV.


Detectors

Spectrum taken with the HEFT 8 × 8 pixel prototype CdZnTe detector coupled to our custom low-noise ASIC readout chip. The detector was cooled to −25 °C.
