Detector HighlightsDetector Highlights• MAR-165 CCD detectors (2)

One funded by GSECARS-NSF and second by NSF-MRI UNLV/Dera single-crystal diamond cell grant.

• MAR-345 online image plate

GSECARS now has 2, new one funded by GSECARS-NSF

• Roper visible light CCDs

4 new cameras for LVP, tomography, diagnostics


Detector HighlightsDetector Highlights• Silicon Drift Diode detectors for energy-dispersive spectroscopy

GSECARS has 4-element detector on 6-month loan from SII under SBIR grant, being used right now.

Second 8-element (?) detector to be funded by grant to Kathy Kitts at NIU.

• Pilatus Pixel Array detector

State of the art detector. 500x200 array of 170x170 micron pixels. Each pixel has energy discriminator and 20-bit counter. Can count 2MHz/pixel, more than 200 frames/second.

Revolutionary for surface diffraction.

Could be used for very fast diffraction studies


Hardware Development HighlightsHardware Development HighlightsBM-C Development (interface diffraction and single-

crystal diffraction at high pressure): •Mirror tank, vertical focusing mirror installed. •Unfocussed monochromator being used, bender being
