Radiation detection is an integral part of basic and applied science, as well as an important tool in international policy. Detectors are utilized for applications ranging from probing the innards of nuclei to verifying the 2015 Iran Nuclear Agreement. Since neutrons are an inevitable signature fissioning material, a common method for finding and monitoring such materials involves neutron detection. Neutron detection is especially challenging because while charged particles and gammas directly ionize a detection medium, neutrons do not. Most neutron detectors therefore require a “conversion” medium that creates a detectable signal. My thesis project has focused on using water – a ubiquitous medium (outside of drought-stricken California) – in order to detect neutrons for nuclear security applications.
The Physics and Astronomy Colloquium Series is open to all members of the university. Unless otherwise noted, talks are held on Thursday afternoons at 4:00-5:20 in Mendocino 1015. Schedule is regularly updated as dates, titles, and abstracts are received. Please check back often. To receive updates about the Colloquium Series, please join our Events Mailing List. For past semesters' series, see our archive.
