The Cit Pellet Injection System: Description and Supporting
The Compact Ignition Tokamak (CIT) will use an advanced, high-velocity pellet injection system to achieve and maintain ignited plasmas. Two pellet injectors are provided: a moderate-velocity (1 to 1 S-km/s), single-stage pneumatic injector with high reliability and a high-velocity (4to 5-km/s), two-stage pellet injector that uses frozen hydrogenic pellets encased in sabots. Both pellet injector...
متن کاملRF-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 کاملA compact lithium pellet injector for tokamak pedestal studies in ASDEX Upgrade.
Experiments have been performed at ASDEX Upgrade, aiming to investigate the impact of lithium in an all-metal-wall tokamak and attempting to enhance the pedestal operational space. For this purpose, a lithium pellet injector has been developed, capable of injecting pellets carrying a particle content ranging from 1.82 × 10(19) atoms (0.21 mg) to 1.64 × 10(20) atoms (1.89 mg). The maximum repeti...
متن کاملCommissioning Results of the Lcls Injector*
The Linac Coherent Light Source (LCLS) is a SASE xray Free-Electron Laser (FEL) project presently under construction at SLAC [1]. The injector section, from drive-laser and RF photocathode gun through first bunch compressor chicane, was installed in fall 2006. Initial system commissioning with an electron beam has recently been completed. The second phase of construction, including second bunch...
