THE TEXAS EXPERIMENTAL TOKAMAK (TEXT) FACILITY

The Texas Experimental Tokamak is a medium-scale tokamak operated as a national user facility. Now in operation, it provides a plasma with a 1-m major radius, 28-cm minor radius, and 400-kA nominal plasma current at up to 3-T toroidal field for pulse lengths of 300 to 500 ms. The facility includes all standard tokamak diagnostics and an integrated data system that makes all data available after each shot, as often as once every 2 min. The design is generally conventional and conservative, the vacuum vessel provides numerous large-aperture radial and vertical ports for complete views of the plasma.
