ICRF Heating
Peaked density profiles may not only improve confinement properties, but also give the additional benefits of increased fusion production and ignition margin in BPX, as shown in Fig. 8.1. The ability to control density profiles in the core and scrape-off regions is governed by a number of both physics and operational considerations that make it difficult to specify optimized fueling systems. Fo...
متن کاملVi. Icrf Heating
Radio-frequency (RF) power in the ion cyclotron range of frequencies (ICRF) has been chosen as the primary auxiliary heating technique for BPX. This decision is based on the wide success of ICRF heating in existing large-scale experiments (JET, TFTR, JT-60), the capability of ion cyclotron waves to penetrate the high-density plasmas of BPX, the ability to concentrate ICRF power deposition near ...
متن کاملIcrf Heating and Profile Control Techniques in Tftr
In fast wave to ion Bernstein wave mode conversion experiments in DT supershot plasmas, localized efficient ion heating rather than electron heating was observed, due to Dopplerbroadened tritium cyclotron resonance overlap into the mode conversion region. The ion temperature heat pulse associated with RF power modulation in this regime could provide a diagnostic tool for measuring the local ion...
متن کاملOperation Results of KSTAR Integrated Control System for First Plasma
After the successful accomplishment of vacuum commissioning assisted by vacuum vessel baking and glow discharge cleaning, KSTAR had shifted to the cool-down phase in April 2, 2008 and completed cooling of all superconducting coils and structures down to the operation temperature of 4.5K for about a month by the helium refrigerator system with 9KW cooling capacity. For the next a month, all supe...
متن کاملElectron Heating by ICRF Mode-Conversion Heating in LHD
Electron heating regime using with radio-frequency waves in the ion cyclotron range of frequencies (ICRF) has been investigated in helical magnetic configuration. Mode-conversion scenario was applied to the LHD plasmas. When the wave frequency is change to be lower than that in the standard ICRF heating (minority ion heating) condition, the resonance layers are moved away to the peripheral regi...
