Los Alamos Fast Camera System was operated on TFTR

Los Alamos scientists collaborated at the Princeton Plasma Physics Laboratory TFTR experiment. Our most recent emphasis was on documenting and understanding disruptions (the sudden and unwanted termination of the plasma current and stored energy). These events are a serious obstacle to building an eventual tokamak fusion reactor, as the energy released to the walls of the vessel can be localized, and cause damage the reactor. As part of our efforts to understand and prevent disruptions, we took high-speed movies of the plasma using a digital intensified Kodak system, which we had recently mounted on a periscope that views into the TFTR vessel.

Glen happy that the fast camera system is successfully reinstalled at PPPL from MIT.

LANL has installed a number of diagnostics on TFTR, and participated in a variety of physics experiments.
