Book Ion Cyclotron Range of Frequency Heating on the Tokamak Fusion Test Reactor

Download or read book Ion Cyclotron Range of Frequency Heating on the Tokamak Fusion Test Reactor written by and published by . This book was released on 1993 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complete ion cyclotron range of frequency (ICRF) heating system for the Tokamak Fusion Test Reactor (TFTR), consisting of four antennas and six generators designed to deliver 12.5 MW to the TFTR plasma, has now been installed. Recently a series of experiments has been conducted to explore the effect of ICRF heating on the performance of low recycling, Supershot plasmas in minority and non-resonant electron heating regimes. The addition of up to 7.4 MW of ICRF power to full size (R ∼ 2.6 m, a ∼ 0.95 m), helium-3 minority, deuterium Supershots heated with up to 30 MW of deuterium neutral beam injection has resulted in a significant increase in core electron temperature (?T{sub e}=3--4 key). Simulations of equivalent deuterium-tritium (D-T) Supershots predict that such ICRF heating should result in an increase in ?{sub alpha}(O) ∼ 30%. Direct electron heating has been observed and has been found to be in agreement with theory. ICRF heating has also been coupled to neutral beam heated plasmas fueled by frozen deuterium pellets. In addition ICRF heated energetic ion tails have been used to simulate fusion alpha particles in high recycling plasmas. Up to 11.4 MW of ICRF heating has been coupled into a hydrogen minority, high recycling helium plasma and the first observation of the toroidal Alfven eigenmode (TAE) instability driven by the energetic proton tail has been made in this regime.

Book Broadband Measurements of Electron Cyclotron Emission in TFTR Tokamak Fusion Test Reactor Using a Quasi optical Light Collection System and a Polarizing Michelson Interferometer

Download or read book Broadband Measurements of Electron Cyclotron Emission in TFTR Tokamak Fusion Test Reactor Using a Quasi optical Light Collection System and a Polarizing Michelson Interferometer written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For the past three years, a Fourier transform spectrometer diagnostic system, employing a fast-scanning polarizing Michelson interferometer, has been operating on the TFTR tokamak at Princeton Plasma Physics Laboratory. It is used to measure the electron cyclotron emission spectrum over the range 2.5 to 18 cm/sup /minus/1/ (75-540 GHz) with a resolution of 0.123 cm/sup /minus/1/(3.7 GHz), at a rate of 72 spectra per second. The quasi-optical system for collecting the light and transporting it through the interferometer to the detector has been designed using the concepts of both Gaussian and geometrical optics in order to produce a system that is efficient over the entire spectral range. The commerical Michelson interferometer was custom-made for this project and is at the state of the art for this type of specialized instrument. Various pre-installation and post-installation tests of the optical system and the interferometer were performed and are reported here. An error propagation analysis of the absolute calibration process is given. Examples of electron cyclotron emission spectra measured in two polarization directions are given, and electron temperature profiles derived from each of them are compared. 34 refs., 17 figs.
