Abstract
The LT-4 is a relatively small (major radius 0·5 m, minor radius 1'10· 1 m) experimental tokamak using a homopolar generator as its main power source to produce a toroidal field of 3 T. A fast currentforcing feedback control system maintains the plasma position constant to 1'1 1 mm. Fairly standard diagnostics are supported by a data acquisition system which handles 200 kbytes of data through 70 CAMAC controlled ADCs per discharge. Illustrative examples of data obtained during .typical operation show magnetohydrodynamic (MHD) activity (magnetic pick-up coils and soft X-ray detectors) as well as relaxation oscillations within the plasma.https://doi.org/10.1071/PH840137
