RF-driven Energetic Tritium Ion Tail Measurements in TFTR Using the Pellet Charge Exchange Diagnostic
Charge exchange interactions of ions with the ablation cloud of an injected lowZ impurity pellet can be used to measure the energy spectrum and radial profile of confined fast ions in a fusion plasma. On TFTR, we use this technique to directly measure energetic alphas from D-T reactions, tritons from D-D reactions, and RFdriven minority tail ions (e.g., H, 3He, T). This paper describes the stat...
متن کاملWall conditioning with impurity pellet injection on TFTR
Solid lithium and boron pellets have been injected into TFTR plasmas to improve plasma performance by coating the graphite inner wall bumper limiter with a small amount of lower Z pellet material, which reduces the influx of carbon from the walls and reduces the edge electron density. This new wall conditioning technique has been applied successfully when continued He conditioning discharges, w...
متن کاملCharge-exchange neutral hydrogen measurements in TFTR using Pd-MOS microsensors
An array of Pd-metal-oxide semiconductor (Pd-MOS) diodes has been used to monitor the fluence and energy of c~rge-exch~ge neutral hydrogen isotopes striking the wall of the Tokamak Fusion Test Reactor (TFTR). The array was positioned 4 cm behind the graphite-tiled waI1 at the toroidal midplane and exposed to several hundred plasma discharges. Hydrogen isotopes striking the Pd-MOS diodes were de...
متن کاملCharge exchange spectroscopy as a fast ion diagnostic on TEXTOR.
An upgraded charge exchange spectroscopy diagnostic has been taken into operation at the TEXTOR tokamak. The angles of the viewing lines with the toroidal magnetic field are close to the pitch angles at birth of fast ions injected by one of the neutral beam injectors. Using another neutral beam for active spectroscopy, injected counter the direction in which fast ions injected by the first beam...
