Title: Microwave Analysis with Monte Carlo Methods for ECH Transmission Lines

Abstract

A new code framework, MORAMC, is presented which model transmission line (TL) systems consisting of overmoded circular waveguide and other components including miter bends and transmission line gaps. The transmission line is modeled as a set of mode converters in series where each component is composed of one or more converters. The parametrization of each mode converter can account for the fabrication tolerances of physically realizable components. These tolerances as well as the precision to which these TL systems can be installed and aligned gives a practical limit to which the uncertainty of the microwave performance of the system can be calculated. Because of this, Monte Carlo methods are a natural fit and are employed to calculate the probability distribution that a given TL can deliver a required power and mode purity. Several examples are given to demonstrate the usefulness of MORAMC in optimizing TL systems.

It primarily consists of a mode propagation solver, MORA; a transmission line deflection solver, DEFLECT; and a set of libraries that handle the Monte Carlo analysis, MORALIB. For sophisticated analysis, computer-aided design (CAD) and finite element analysis codes (FEA) can be incorporated.

Design and Analyses of Transmission Lines for the 110 GHzECH Upgrade to 6 MW for DIII-D

Technical Report Grunloh, H.J. ; Baxi, C.B. ; Chin, E. ; ...

During the summer of 1999 the installation of three new Electron Cyclotron Heating (ECH) transmission lines began as part of the 110 GHz ECH Upgrade to 6 MW project for DIII-D. An important step in the development of the transmission line design was the selection of the waveguide size. To make this selection, analyses were conducted to characterize the thermal and radio frequency (rf) loss performance of the key corrugated waveguide components under 1 MW, long pulse (10 s, 1% duty cycle) operation. Other factors that were analyzed included vacuum conductance and pumping speed, ease of installation, space considerations, andmore »« less

Active and Passive RF Components for High-Power Systems

Technical Report Nantista, Christopher D.

In recent years, R&D for pulse compression and power distribution systems for the Next Linear Collider has led to the invention of many novel rf components, some of which must handle up to 600 MW of pulsed power at X-band. These include passive waveguide components, active switch designs, and non-reciprocal devices. Among the former is a class of multi-moded, highly efficient rf components based on planar geometries with overmoded rectangular ports. Multi-moding allows us, by means of input phasing, to direct power to different locations through the same waveguide. Planar symmetry allows the height to be increased to improve powermore »« less

Protecting against damage from refraction of high power microwaves in the DIII-D tokamak

Journal Article Lohr, John ; Brambila, Rigo ; Cengher, Mirela ; ... - EPJ Web of Conferences

Here, several new protective systems are being installed on the DIII D tokamak to increase the safety margins for plasma operations with injected ECH power at densities approaching cutoff. Inadvertent overdense operation has previously resulted in reflection of an rf beam back into a launcher causing extensive arcing and melt damage on one waveguide line. Damage to microwave diagnostics, which are located on the same side of the tokamak as the ECH launchers, also has occurred. Developing a reliable microwave based interlock to protect the many vulnerable systems in DIII-D has proved to be difficult. Therefore, multiple protective steps havemore »« less

LOSS ESTIMATE FOR ITER ECH TRANSMISSION LINE INCLUDING MULTIMODE PROPAGATION

Journal Article Shapiro, Michael ; Bigelow, Tim S ; Caughman, John B ; ... - Fusion Science and Technology

The ITER electron cyclotron heating (ECH) transmission lines (TLs) are 63.5-mm-diam corrugated waveguides that will each carry 1 MW of power at 170 GHz. The TL is defined here as the corrugated wave guide system connecting the gyrotron mirror optics unit (MO U) to the entrance of the ECH launcher and includes miter bends and other corrugated wave guide components. The losses on the ITER TL have been calculated for four possible cases corresponding to having HE(11) mode purity at the input of the TL of 100, 97, 90, and 80%. The losses due to coupling, ohmic, and mode conversionmore »« less
High-power microwave transmission and launching systems for fusion plasma heating systems

Conference Bigelow, T.S.

Microwave power in the 30- to 300-GHz frequency range is becoming widely used for heating of plasma in present-day fusion energy magnetic confinement experiments. Microwave power is effective in ionizing plasma and heating electrons through the electron cyclotron heating (ECH) process. Since the power is absorbed in regions of the magnetic field where resonance occurs and launching antennas with narrow beam widths are possible, power deposition location can be highly controlled. This is important for maximizing the power utilization efficiency and improving plasma parameters. Development of the gyrotron oscillator tube has advanced in recent years so that a 1-MW continuous-wave,more »« less
