workshops & special sessions

The MARC conference will hold workshops for the first time. A total of six or seven workshops are anticipated being held on Sunday (March 25, 2012) , and a separate special session on Fukishima to be held during the evening during after regular sessions have concluded. The schedules will be established early in 2012. Sunday workshop sessions are expected to be held from 9-11 and 1-3. We anticipated three workshops being held concurrently in each session (so three from 9-11 and three more from 1-3). Titles, organizers and summaries for each will be posted below as details are developed. Please contact Steve LaMont or Sam Glover if you have any questions.

Sunday workshops sessions

Federally Sponsored R&D: Is it meeting the needs of the Radiochemistry Community?

Panel Discussion: Representatives from the Federal Funding Programs and other select entities will be requested to present information on funding allocations for the past three years as well as projections of funding allocations anticipated for FY 2013. A focused question and answer session will follow to identify the needs of the research community and establish how well they are being met by existing programs. Anticipated topics will cover direct funding to students, infrastructure improvement needs (particularly to the type and scale of the projects), Research and Development and other mechanisms for improving the state of the University community. Presenters are sought who may have direct insight into the currently existing programs and the needs of the community at large. (Currently expected speakers should represent the DOE-NE, NRC, NNSA, DTRA and DHS programs.)

Guide to the Expression of Uncertainty in Measurements for Nuclear Safeguards

The international organization for standardization (ISO) developed the Guide to the Expression of Uncertainty in Measurements (GUM) as a standardized way of expressing uncertainty in measurements. GUM is a step-by-step approach that can be applied to measurements of all kinds, and its use facilitates research and development, enforcement of laws and regulations, trade, international comparison of measurement standards, quality assurance, and judgment of safety risks. The workshop provides an introduction to the GUM principles as applied to nuclear safeguards measurements. The following topics will be covered (i) review of the applicable statistical principles, (ii) step-by-step approach to evaluation of uncertainty following GUM, and (iii) application of GUM concepts to nuclear safeguards measurements with thermal ionization mass spectrometry being used as case study.

Analysis of high-resolution nuclear spectra with the Cambio application.
Organized by G.P. Lasche, Sandia National Laboratory; and R.L. Coldwell

Popular nuclear spectral analysis applications typically use either the results of a peak search or the best match of a set of linear templates as the basis for their conclusions. These proven methods work well in controlled environments. However, they often do not perform well in cases where the critical information resides in well-masked peaks, or where the data is sparse and good statistics cannot be obtained, and where little is known about the detector that was used. To address these limitations, non-linear fitting techniques have been introduced into an application called "Cambio" suitable for public use. With this approach, free parameters are varied in iterative steps to converge to values that minimize differences between the actual data and the functions that describe the fit to the data. A single parameter that represents the effect of each nuclide on the entire spectrum is varied simultaneously together with other user-selected parameters for energy calibration, attenuation by intervening matter, detector resolution, and peak-shape deviations. After a brief overview of Cambio's approach to analysis, workshop attendees will be provided with Cambio free of charge, enabled for analysis, and will be guided step-by-step through the analysis of several interesting high-resolution nuclear spectra with Cambio. Because the intent will be to provide practical, guided analysis with Cambio, it is recommended that attendees bring their own laptop computers so that they can best benefit from the workshop. Please contact George Lasche with any questions regarding this workshop.

New Methods for Cooling HPGe Detectors

The last decade has witnessed great advances in mechanical cooling options for HPGe detectors. While these technologies are not developed with the gamma spectroscopy industry, all have benefited from the advances. The size and weight of these coolers has decreased, while the sophistication and reliability have increased. This workshop will explore various cooler technologies now available and there potential applications within the gamma spectroscopy community.

Advances in DSP Instrumentation, and Supporting Program Languages

Although the use of Digital Signal Processing (DSP) is not a new technology in gamma spectroscopy, the basic concepts and benefits of using DSP are still not fully understood in the community. In addition, future applications for more sophisticated DSP implementations are being generated everyday. In addition, Software Development Kits (SDK's ) have become common for most Gamma Spectroscopy hardware. The combination of these two features is opening up measurement possibilities that are supporting a new range of applications. This workshop will explore the basic principles behind DSP in gamma spectroscopy and some examples of the application benefits under various parameter ranges such as throughput, detector size and resolution variations as well as a review of the Software Development Tools currently available.
