28 I n practical terms, the project’s goal is to construct and operate a tokamak experiment which can confine a deuterium-tritium plasma in which the α-particle heating dominates all other forms of plasma heating. Formally, the primary mission of the ITER project is to demonstrate sustainment of a DT plasma producing ~500 MW of fusion power for durations of 300 500 s with a ratio of fusion outp...

An experimental investigation of shock wave induced heating and compression in planar targets relevant to direct-drive inertial confinement fusion (ICF) was conducted on the OMEGA laser system. A physical understanding of shock wave heating, radiative heating, and heating by energetic electrons in direct-drive ICF is necessary because the achievement of energy gain requires accurate control of ...

Background—We sought to clarify, using functional and biological approaches, the role of epoxyeicosatrienoic acids, nitric oxide (NO)/reactive oxygen species balance, and endothelin-1 in conduit artery endothelial dysfunction during essential hypertension. Methods and Results—Radial artery diameter and mean wall shear stress were determined in 28 untreated patients with essential hypertension a...

The timescale for energy release is an important parameter for constraining the coronal heating mechanism. Observations of “warm” coronal loops (∼ 1MK) have indicated that the heating is impulsive and that coronal plasma is far from equilibrium. In contrast, observations at higher temperatures (∼ 3MK) have generally been consistent with steady heating models. Previous observations, however, hav...

Results of ICRF heating experiments in Alcator C-Mod during the November 1994 June 1995 campaign are summarized. Efficient heating of high density ( , ; 3 x 1020 m-3 ) plasmas was demonstrated with high power densities (up to 5 MW/m 3 volume averaged, 0.6 MW/m 2 surface averaged). These experiments were carried out with RF powers up to 3.5 MW at 80 MHz, at magnetic fields up to 8 T and plasma c...

We have performed a series of idealized MHD calculations of the response of an anode plasma layer to the rising magnetic field in an applied-B ion diode. The purposes of this study were to consider Joule heating of the plasma layer, which could pose potential problems for lithium ion diodes, and the leakage of flux behind the ion-emitting surface, which is related to impedance collapse. We find...
