GSECARS has embarked on a significant reconfiguration of the entire setup at 13-ID as they prepare to upgrade to two canted undulators. The upgrade will be funded by $2.3 million provided by DOE, NASA, and NSF and by part of the $5.6 million awarded to the APS under the American Reinvestment and Recovery Act (ARRA).
The ARRA money (and existing APS staff and resources) will support design, fabrication, and installation of the two undulators and a new front end. Outside the shield wall, the main work will involve splitting the C station into two stations. The new C1 station will house a next generation, submicron microprobe; one undulator will be dedicated to this station and optimized for these lower energy microprobe studies. In the C2 station, the diffractometer, diamond anvil cell apparatus, and multi-anvil press will share the second undulator, which will be optimized for high energy. A new personnel door will be installed and the control area will be rearranged. There's a lot of detailed design work ahead. Fortunately, the D station will remain unchanged! The project started this fall and will take two years to complete. GSECARS aims to accomplish all this without losing any user operation time!
In response to a request for an administrative supplement for its active grant from the National Center for Research Resources/NIH, BioCARS received $342,000 in additional funding (the request was not part of the ARRA program). The funds will support several important 14-ID enhancements in the coming year and will help accelerate the tempo of the current scientific research program at BioCARS.
Planned improvements include a suite of new optics and instrumentation to support micro-crystal studies and time-resolved crystallography, a new high-heat-load X-ray chopper, an automated door for the 14-ID-B experimental station, and a new timing module that will enhance the flexibility and capability in supporting time-resolved studies.
The instrumentation and optics suite for microcrystallography will now include high-precision translation stages, a KB mirror system for secondary focusing, and submicron positioning stages and controller for fine positioning of small crystals. New items for time-resolved studies will include a new electronics board for the nanosecond laser, a high-intensity cw Xe lamp, spectrometers for broadband absorption and fluorescence measurements, an additional objective for the microspectrophotometer (for fluorescence measurements), and a programmable syringe pump for time-resolved flow-cell crystallography and solution scattering experiments.

The management contract between CARS and IMCA ended on December 31, 2009. Under the five-year contract, CARS provided technical expertise with the objective of upgrading 17-ID to a state-of-the-art high-throughput facility for structural biology in support of drug design. The upgrade is complete, and 17-ID now provides a very stable, very small beam with high flux, made possible by state-of-the-art adaptive optics. IMCA has reached a new management agreement with Hauptman Woodward Medical Research Institute. [top]
August 15, 2009, marked the end of a contract with FermiScan, a company seeking to develop a diagnostic method for breast cancer based on x-ray analysis of hair. Under the contract, CARS provided technical support and hosted a visiting scholar, Gary Corino. [top]
The small-angle scattering instrument at 15-ID will resume operation early in 2010 under a collaborative agreement between CARS and the APS. The APS ultra-small-angle scattering (USAXS) program at the APS, headed by Jan Ilavsky, will move to 15-ID-D and will operate within the ChemMatCARS user program. [top]
The administrators ask that you schedule all conference room use. You can check the room availability through the APS conference room calendar, available by local or VPN access (434 schedule). To schedule room 434-C010, contact Katie Tietz, 2 0450, firstname.lastname@example.org. [top]
Among the newest members of the CARS staff is Yongseong (Yong) Choi, who has been quietly plying his trade since November 2008 as a beamline scientist in GSECARS, responsible for x-ray microprobe and spectroscopy experiments. However, before joining the staff, Yong was no stranger to CARS, as his postdoctoral position with Kathy Kitts at Northern Illinois University (2008) was largely based here. Prior to that, he held a postdoctoral position in the Materials Science Division at Argonne. Yong received his Ph.D. in materials science and engineering from Northwestern University in 2005, where he studied the properties of magnetic materials. [top]
Patrick Dell officially joined the CARS staff in December as a Mechanical Design Engineer, working primarily in GSECARS. He can be reached at email@example.com. Patrick was previously on the staff of the University of Chicago Engineering Center and had already been supporting GSECARS in his current role. [top]
ChemMatCARS 2009 summer employee Janet Soltau was one of 100 DOE-funded undergraduate researchers selected to present their posters at a competition on November 8 and 9 at Oak Ridge National Laboratory. Janet is presently a senior majoring in physics, math, and education at the University of Vermont; she plans to become a science teacher. Her work at ChemMatCARS, conducted with Binhua Lin, K.I. Kim, and Brian Leahy of the University of Chicago, was supported by the Pre-Service Teachers program of Argonne's Division of Educational Programs. Her poster, titled "Silver Nanoparticle Monolayer Surface Morphology," is presently on display at the entrance to the 15-ID control area.
