Physics & Astronomy Colloquium at CSU Long Beach

Radiography at the Nevada National Security Site

Cygnus Facility

Stephen E. Mitchell

Nevada National Security Site

May 1, 2017
Time: 11:15am
Refreshments at 10:45am

The Nevada National Security Site (NNSS) Cygnus facility routinely operates a powerful X-ray machine capable of delivering energy in the form of penetrating radiation to study transuranic materials under extreme dynamic conditions. This form of radiation is derived from electrical energy produced from a pulsed power machine and converted to x-ray radiation from a thick-target Bremsstrahlung converter. The x-ray radiation is fast, intense, and energetic enough to penetrate an object under stress and produce a radiograph rich in information revealing areal, volumetric density, and surface/interface profiles to support laboratory code and simulation development. In this presentation, a survey of radiographic chain components, analysis, and techniques is presented to educate and inspire next-generation scientists, mathematicians, and engineers to advance the art.

All Physics students & faculty should attend!

See the colloquium schedule and its archive of previous talks

Colloquia are scheduled to start Mondays at 11:15am sharp in Peterson Hall 2, Room 126 (PH2-126). Refreshments are served from 10:45am to 11:05am in Room HSCI-224 (next to the department office) and everyone is invited to mingle with faculty and students!
