The Enormous Toroidal Plasma Device (ETPD) is an experimental physics device housed at the Basic Plasma Science Facility at University of California, Los Angeles (UCLA). It previously operated as the Electric Tokamak (ET) between 1999 and 2006 and was noted for being the world's largest tokamak before being decommissioned due to the lack of ...

The characteristic torus-shaped chamber is clad with graphite to help withstand the extreme heat. A tokamak ( / ˈtoʊkəmæk /; Russian: токамáк) is a device which uses a powerful magnetic field generated by external magnets to confine plasma in the shape of an axially-symmetrical torus. [1]
A. The Enormous Toroidal Plasma Device. Figure 1 shows the device itself, consisting of a toroidal vacuum chamber with major radius 10 meters and rect-angular cross section: 2 meters horizontally by 3 meters vertically. The plasma chamber maintains a dynamic vacuum in the range 1 4 mTorr.
Other experimental devices ETPD: The Enormous Toroidal Plasma Device (ETPD) The ETPD device is housed on the main floor of the STRB building. The device was originally constructed as a tokamak and if run in that mode, it would still be the physically-largest tokamak in the world. Figure 1, left: Photograph of the ETPD device.
