The J. Bennett Johnston, Sr., Center for Advanced Microstructures and Devices (CAMD), Louisiana State University, plans to hold a workshop or workshops related to synchrotron X-ray based analytical techniques. Some of these techniques were considered as parts of workshops organized at CAMD over the past few years (2000-2004). The instructors will mostly include faculty and researchers from the LSU campus and CAMD. For some methods, external instructors will be used.
The techniques include:
These X-ray based techniques are also used in the laboratory, but the characteristics of synchrotron radiation provide some unique advantages which cannot be replicated elsewhere. They are used in a wide variety of disciplines ranging from archeology to environmental sciences to materials science to zoology.
The emphasis of the workshop will be more on practice than theory. Theory will be covered as needed. The goal of the workshop is to introduce new researchers to synchrotron X-ray radiation based techniques and, ultimately, turn them into productive users at CAMD. Users who are somewhat proficient in these techniques may also get new insights. Potential users may discuss applications of these techniques with CAMD staff. Beamline scientists at CAMD can help individual researchers with his or her personal education.
A participant may attend lectures and hands-on demonstrations related to one technique or all of them. More emphasis will be placed on hands-on demonstrations in small groups. The workshop will also point to Internet based resources which can allow an individual to become more conversant with these techniques. If successful, this type of workshop can be held more frequently.
We have included with the workshop two general lectures on synchrotron radiation, characteristics of the CAMD ring, and some rudimentary X-ray physics. We can decide about the schedule of the hand-on sessions with the CAMD staff at the individual workshops. All lectures will be held in CAMD Conference Room. It has been difficult to schedule all these workshops with so many constraints, such as spring break, American Chemical Society meeting in New Orleans, etc. We are also trying to bring one or more external speakers for small angle X-ray scattering.
The following is the tentative schedule for the workshops:
