CHESS capillaries are designed to have rotationally symmetric ellipsoidal shapes to intercept a large beam area, and thus are suitable focusing optics for current CHESS beamlines which delivers an x-ray beam into 10~50um spot sizes with large x-ray flux.
The program’s name SRCCS, stands for Summer Research for Community College Students. Thanks to several volunteer mentors, we have exciting projects especially designed for SRCCS participants posted on our website: https://www.classe.cornell.edu/StudentOpportunities/SrccsProgram.html.
The annual awards support women life scientists conducting innovative, risk-taking research.
Margaret Bynoe, associate professor of immunology in the College of Veterinary Medicine; Carolyn Sevier, assistant professor of molecular medicine, also in the veterinary college; and Olena Vatamaniuk, associate professor of crop and soil sciences in the College of Agriculture and Life Sciences, each received awards of $15,000.
However, the "stopping power" of silicon is limited; it doesn't efficiently absorb (and ultimately detect) x-rays of energies above approximately 20 keV. For x-ray science applications at higher energies (which are the primary mission of CHESS) different approaches are required; using Cadmium Telluride (CdTe) as a sensor material is one of them. The Gruner group at Cornell has chosen to develop CdTe-based versions of the world-leading MM-PAD and Keck PAD detectors, to allow experiments at x-ray energies up to 200 keV.
The Amazon Basin is a complex network of interconnected terrestrial and aquatic environments, with chemical diversity dictated by the bedrocks and soils through which river tributaries pass. Overfishing has led to considerable declines in some species, while deforestation is producing stronger, earlier flood pulses, altering the flood cycle that migratory fishes rely upon.
The planning for the CESR upgrades is well under way, with Dave Rice leading the charge. The beamline project is being led by Chris Conolly. The beamline design process has taken a methodical path involving our user community, scientific advisory panels, and an external review committee that met on Friday, December 16th.
The failure of these materials begins at the microscale, often deep within the bulk of the deforming material, with the formation of voids and cracks. Typically, failure of this type must be studied forensically using destructive optical or electron microscopy post-mortem, making the causes of the failure difficult to determine. With new in-situ high-energy X-ray techniques, long standing questions regarding the initiation of material failure can be answered, improving our ability to produce lightweight, long-lasting engineering components.
Along their way they stopped at middle schools across the country to teach hands-on lessons on renewable energy based on a mini 3D printed solar-powered bicycle called SolCycle. In the fall, one of the students, Elizabeth Case, enrolled at Cornell University as a graduate student and contacted Xraise to collaborate on enhancing the lesson plan and to make it more accessible to teachers across the nation.
The upgraded controls are similar to the A-Line controls and consists of a PLC driven touch screen interface which controls the station beam stops, and shows the status of the safety interlock devices for the station. The screen and PLC are connected to the CHESS controls and data network, which allows the status of other networked equipment to be displayed. At the A1 station, users and staff can now see the status of upstream beamline components to aid in beamline setup.
