Canted 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 Now submitting split funding proposals to NASA, NSF, and DOE (~$700K each)
