The ‘Mega Ampere Speherical Tokamak’ (MAST), has a typical plasma volume ± 7m3 and aspect ratio 1.3 to 1.4. It is equipped with a broad range of diagnostics including a high resolution, single pulse, Ruby laser TS system with 284 radial points, and a lower spatial resolution Nd:YAG system with 19 radial points (presently being upgraded), running at 200Hz. These are complemented by a scanning reflectometer, primarily intended for fast density profile measurement, and technically similar to the one on AUG (Silva [1]), except that there are only 3 channels and they are all on the low field side of the plasma. |
