Led by Master Teacher Charles Canestaro, of the Cortland Enlarged City School District, the group started the day with the ever popular Foutan Boards kit. The boards, one of the most charismatic items offered by CHESS’s Physics Teachers Lending Library, gave the teachers an opportunity to learn about the structure and behavior of current and voltage in circuits.
Anatoly came to CHESS as a postdoc in Christine Papadakis’ group at the Technical University of Munich. In two experimental runs at D-line he explored solvothermal annealing of block copolymers, at this point the most complex annealing method. Solvothermal annealing is an extension of solvent vapor annealing [1] at room temperature which has been studied extensively by the collaborating groups of Christine Papadakis and Dorthe Posselt (Roskilde University, Denmark) over many years at CHESS.
Nearly four years ago, Justin Mach, an engineering specialist at Caterpillar, was invited by Armand Beaudoin, associate director of Insitμ, to work with CHESS on materials research that could be of benefit to the company. Mach conducted Caterpillar’s first experiment with CHESS in December 2014 to help validate a model of how residual stress occurs during welding. Caterpillar has continued this collaboration with both CHESS and the Advanced Photon Source (APS) to aid in further research and development in welding and in other processing stages of materials.
Chris Conolly looks at the concrete floor of Wilson Lab, eyeing up the numerous holes drilled by one of the contractors for the upgrade project. These one-inch holes pockmark the 10,000sf experimental hall of the Wilson Synchrotron Laboratory. In a way, these holes represent the numerous experiments conducted over the past 50 years.

The compound, kanglemycin A, is related to the antibiotic rifampicin, according to Katsuhiko Murakami, professor of biochemistry and molecular biology at Penn State and one of leaders of the project. “Rifampicin is already part of the cocktail of antibiotics used to treat tuberculosis, but many strains of the tuberculosis-causing bacteria have developed resistance to it,” Murakami said.
In early 2019, CHESS-U will have an increased energy of the electron beam, from 5.3 to 6.0 GeV, double the current from 100 to 200 mA, and reduction of the horizontal emittance of the x-ray beam from 100nm to 30nm.
