Plasma performance of TEXTOR after pellet injection
The injection of pellets into tokamak discharges leads to a density increase, to the excitation of modes, to a profile peaking and to an improvement of the confinement. Here two topics are treated: (i) the profile peaking after the pellet injection as a function of the plasma current and the safety factor q(a); (ii) the mode excitation in runaway discharges and its influence on the runaways. An important diagnostic tool used for these measurements is the synchrotron radiation generated by the runaways. The emission of the synchrotron radiation allows the use of runaways as probes for the central plasma.
