Abstract:
The Measurement Science Group has played a major role in the development of projects such as the Time Projection Chamber, the KECK 10 meter telescope, Ge-76 dark matter measurement, and more recently Gammasphere all of which required substantial advances in instrumentation techniques and technologies. More recently the group was asked by DOE/OIT to help in the detection of orphaned radioactive sources buried in steel scrap. The orphaned source in steal scrap problem is a low level counting problem with many similarities to the detection of "dirty bombs". Developments underway include the now well recognized field operable, germanium based, spectrometric systems (CRYO3 a joint development with LLNL), imaging systems for gamma-rays and low energy X-rays diffraction applications with high spatial resolution, high event rate imagers.

The speakers will present an overview of the group activities, describe some of the instrumentation currently being developed and the group's approach to problem solving.
