Title: Antenna-plasma coupling calculations for the ITER low-field side reflectometer

Abstract

Here, the antenna-plasma coupling for the ITER low-field side reflectometer system (LFSR) was studied using a hybrid 3D reflectometer simulation code. Reflections from equilibrium profiles were simulated to optimize the power that is coupled the receive antenna. At the optimal coupling the effects of density fluctuations were also calculated, showing that the density fluctuations decrease the average coupling by as much as 6~dB. This study indicates that after some minor changes to the proposed design of this reflectometer system, the antenna-plasma coupling of the ITER LFSR is sufficient to design and build a system that meets the required specifications.

Preliminary design overview and performance assessment of the ITER low-field side reflectometer

Journal Article Muscatello, Christopher M. ; Anderson, Clayton ; Anderson, James Paul ; ... - Nuclear Fusion

The design of the ITER low-field side reflectometer (LFSR) has matured to a complete end-to-end preliminary design. LFSR will supply three key plasma measurements: (1) electron density profile, (2) electron density fluctuations, and (3) poloidal rotation. Simultaneous measurements of the three quantities are enabled by an array of six monostatic antennas which inject from an equatorial port on the outboard side of the ITER vessel. Low-loss transmission lines, consisting of corrugated, overmoded waveguide and miter bends, transmit the 30–165 GHz, O- and X-mode signals to and from the ITER plasma. Integrated transmission-line components serve a range of purposes, such asmore »« less

Performance demonstration of vacuum microwave components critical for the operation of the ITER low-field side reflectometer

Journal Article Muscatello, C. M. ; Anderson, J. P. ; Boivin, R. L. ; ... - Review of Scientific Instruments

Final design studies in preparation for manufacturing have been performed for functional components of the vacuum portion of the ITER Low-Field Side Reflectometer (LFSR). These components consist of an antenna array, electron cyclotron heating (ECH) protection mirrors, phase calibration mirrors, and vacuum windows. Evaluation of these components was conducted at the LFSR test facility and DIII-D. The antenna array consists of six corrugated-waveguide antennas for simultaneous profile, fluctuation, and Doppler measurements. A diffraction grating, incorporated into the plasma-facing miter bend, provides protection of sensitive components from stray ECH at 170 GHz. For in situ phase calibration of the LFSR profile reflectometer,more »« less

Thermal Loads and Cooling Design for ITER in-Port Low Field Side Reflectometer Diagnostic System

Journal Article Wang, Wenping ; Zolfaghari, Ali ; Neilson, Hutch ; ... - Fusion Engineering and Design

The current design for the ITER Low Field Side Reflectometer (LFSR) diagnostic system contains six circular waveguides that function as both launch and receive antennas. The front end of LFSR system, interfacing with the plasma facing DFW and its supporting diagnostic shielding Modules (DSM), is integrated into Equatorial Port Plug 11(EPP#11). In-vessel LFSR configuration is mainly divided into two sections, i.e. Front Antenna Unit (FAU) and in-vessel Transmission Line (TL) components. During plasma normal operation, the 14 MeV neutrons from D-T fusion reactions penetrate into the port plug and LFSR components. Neutronics code ATTILA is used for assessing the volumetricmore »« less

Optimization studies of the ITER low field side reflectometer

Journal Article Diem, S J ; Wilgen, J B ; Bigelow, T S ; ... - Review of Scientific Instruments

Microwave reflectometry will be used on ITER to measure the electron density profile, density fluctuations due to MHD/turbulence, edge localized mode (ELM) density transients, and as an L-H transition monitor. The ITER low field side reflectometer system will measure both core and edge quantities using multiple antenna arrays spanning frequency ranges of 15-155 GHz for the O-mode system and 55-220 GHz for the X-mode system. Optimization studies using the GENRAY ray-tracing code have been done for edge and core measurements.
