Harmonic Metrics and Connections with Irregular Singularities
We identify the holomorphic de Rham complex of the minimal extension of a meromorphic vector bundle with connexion on a compact Riemann surface X with the L 2 complex relative to a suitable metric on the bundle and a complete metric on the punctured Riemann surface. Applying results of C. Simpson, we show the existence of a harmonic metric on this vector bundle, giving the same L complex. As a ...
متن کاملHigh efficiency quasi-optical mode converters for overmoded gyrotrons
This thesis reports on the design and experimental verification of two novel high efficiency quasi-optical mode converters for gyrotron oscillators. Gyrotrons produce high order TEm,p modes (m, p > > 1) at high frequencies (100-300 GHz). These modes must be converted to low order linearly polarized modes for transmission in corrugated waveguides or open mirror transmission lines. Because tradit...
متن کاملNonstationary oscillations in gyrotrons
The onset of stochastic oscillations in gyrotrons is studied by means of the self-consistent theory describing nonstationary processes. Complicated alternating sequences of regions of stationary, automodulation, and chaotic oscillations are found in the plane of the generalized gyrotron variables: cyclotron resonance mismatch and dimensionless current. The results of the investigations are impo...
متن کاملHigh Frequency Gyrotrons and Their Application to Tokamak Plasma Heating
High frequency (> 200 GHz) gyrotrons are potentially useful for several important applications, including plasma heating and radar. For electron cyclotron resonance heating of a moderate-size, high power density tokamak power reactor to ignition temperatures, a gyrotron frequency around 200 GHz appears to be necessary. The design of high frequency gyrotrons is discussed. Analysis of overall gyr...
متن کاملHarmonic Systems with Bulk Noises
We consider a harmonic chain in contact with thermal reservoirs at different temperatures and subject to bulk noises of different types: velocity flips or self-consistent reservoirs. While both systems have the same covariances in the non-equilibrium stationary state (NESS) the measures are very different. We study hydrodynamical scaling, large deviations, fluctuations, and long range correlati...
