Canted Undulator UpgradeCanted Undulator Upgrade

• Proposal submitted to APS SAC Dec. 2006, very positive response. APS will contribute $1.5M for undulators and front-end components

• Greatly increases time for high-pressure, microprobe is separated and runs 100% of time

• Allows new undulators optimized for high-energy (high-pressure) and low-energy (spectroscopy, microprobe)

• Unsuccessful in getting Univ. of Chicago MRI slot for Jan 2008.• Now submitting split funding proposals to NASA, NSF, and DOE (~$700K each)

GSECARS Near Term Goals Pursue funding and (hopefully) design and

construction of canted undulators. Bring the 13-BM-C station fully online with

scientific programs in interface diffraction and single-crystal diffraction at high pressure

Complete D-DIA30 project Bring CO2 laser heating for the DAC in 13-
