Two-dimensional full wave simulation of microwave reflectometry on Alcator C-Mod

A new 2-D full-wave code has been developed to simulate ordinary (O) mode reflectometry signals caused by plasma density fluctuations. The code uses the finite-difference time-domain method with a perfectly-matched-layer absorption boundary to solve Maxwell’s equations. Huygens wave sources are incorporated to generate Gaussian beams. The code has been used to simulate the reflectometer measure...

Plasma wave simulation based on versatile FEM solver on Alcator C-mod

The finite element method (FEM) has the potential of simulating plasma waves seamlessly from the core to the vacuum and antenna regions. We explored the possibility of using a versatile FEM solver package, COMSOL, for lower hybrid (LH) wave simulation. Special care was paid to boundary conditions to satisfy toroidal symmetry. The non-trivial issue of introducing hot plasma effects was addressed...

Neutrals studies on Alcator C-Mod

The high neutral densities and short neutral mean free paths in the Alcator C-Mod divertor have provided a unique testing ground for our understanding of the role of neutrals in a tokamak. The high neutral pressures found in the C-Mod divertor can only be reproduced in models by including such collisional processes as ion-neutral and neutral-neutral collisions, neutral viscosity, as well as tak...

Overview of the Alcator C-mod Program Overview of the Alcator C-mod Program

Research on the Alcator C-Mod tokamak has emphasized RF heating, self-generated flows, momentum transport, scrape-off layer turbulence and transport and the physics of transport barrier transitions, stability and control. The machine operates with PRF up to 6 MW corresponding to power densities on the antenna of 10 MW/m. Analysis of rotation profile evolution, produced in the absence of externa...

Core Atomic Physics Studies in Alcator C-mod Core Atomic Physics Studies in Alcator C-mod

The Rydberg series (1s – 1snp) up to n=14 of helium-like argon (Z=18) has been observed from Alcator C-Mod plasmas using a high resolution x-ray spectrometer array. High n satellites to these lines of the form 1s2s – 1s2snp and 1s2p – 1s2pnp with 3 ≤ n ≤ 12 have been recorded. X-ray spectra of 2l nl′ transitions with 3 ≤ n ≤ 18 in molybdenum (Z=42) and 3 ≤ n ≤ 12 in krypton (Z=36) and niobium (...
