A quiescent plasma is sustained for 80 energy confinement times by only gas fuelling and neutral beam heating in an axisymmetric region of the Tandem Mirror Experiment Upgrade (TMX-U). This plasma should be unstable because of the bad magnetic curvat

Publikováno v: [Proceedings] The 14th IEEE/NPSS Symposium Fusion Engineering.

The MTX (Microwave Tokamak Experiment) experiment diagnostic capabilities were upgraded, with the addition of five new diagnostics. A second beamline was added on the existing Michelson ECE waveguide to accommodate the new polychromator. This provide

Stark‐effect measurement of high free‐electron laser electric fields in MTX by laser‐aided particle‐probe spectroscopy

Autor: M. Shiho, K. Ohasa, D. G. Nilson, K. Mizuno, Toshiatsu Oda, K. Odajima, Ken Takiyama, J. H. Foote

We are constructing a diagnostic system to measure the electric field (≳100 kV/cm) of a free‐electron laser (FEL) beam when injected into the plasma of the Microwave Tokamak Experiment (MTX). The apparatus allows a crossed‐beam measurement, wit

Thomson scattering diagnostic for the microwave tokamak experiment

Autor: J. J. Jolly, J. D. Barter, J. H. Foote, N. R. Sewall, L. F. Schlander

Publikováno v: Review of Scientific Instruments. 61:2861-2863

The Thomson scattering diagnostic system (TSS) on the microwave tokamak experiment (MTX) at LLNL routinely monitors electron temperature ({ital T}{sub {ital e}}) and density. Typical measured values at the plasma center under clean conditions are 900

Experiments on nonlinear absorption of ECH waves in MTX and a comparison with theory

Publikováno v: AIP Conference Proceedings.

Intense pulse electron cyclotron heating (ECH) experiments have been carried out on the MTX tokamak. Rf pulses at 140 GHz with peak power of 1–2 GW and 25 ns pulse length were generated by the ETA‐II/IM FEL and transported quasi‐optically to MT

Publikováno v: AIP Conference Proceedings.

Single pass absorption experiments using fundamental, O-mode ECH waves have been performed in the Microwave Tokamak Experiment (MTX) and found to be consistent with linear absorption theory, as predicted for the ECH source which is a 140 GHz, 400 kW
