    "abstract": "Decay times of plasma flows and plasma profiles have been measured after a\nsudden biasing switch-off in experiments on the CASTOR tokamak. A biased\nelectrode has been used to polarize the edge plasma. The edge plasma potential\nand flows have been characterized by means of Langmuir and Mach probes, the\nradiation was measured using an array of bolometers. Potential profiles and\npoloidal flows can be well fitted by an exponential decay time in the range of\n10 - 30 microseconds when the electrode biasing is turn off in the CASTOR\ntokamak. The radiation shows a slower time scale (about 1 ms), which is linked\nto the evolution in the plasma density and paticle confinement.",
