Canted Undulator Upgrade Proposal submitted to APS SAC Dec. 2006, waiting for response Greatly increases time for high-pressure, microprobe is separated and runs 100% of time

COMPRES 2007 Annual Meeting Detector 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

COMPRES 2007 Annual Meeting Detector 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

COMPRES 2007 Annual Meeting Hardware Development Highlights BM-C Development (interface diffraction and single- crystal diffraction at high pressure): Mirror tank, vertical focusing mirror installed. Unfocussed monochromator being used, bender being fabricated. In commissioning for surface diffraction this week, DAC experiments soon Proposals in BM-D Brillouin Spectroscopy Instrument Upgrade to diamond cell apparatus COMPRES infrastructure project led by UIUC (J. Bass) Two cycles now run in “user mode” Report at this meeting
