    A review of the experimental study of single-mode oscillators based on stimulated bremsstrahlung and Cerenkov radiation of high-current relativistic electron beams is given. Three types of Cerenkov oscillators are investigated in detail: orotrons, surface wave oscillators and a flimatron (free electron maser (FEM) based on Smith-Purcell radiation). The bremsstrahlung oscillators studied are gyrotr... View full abstract»

  • Openings in a fusion reactor blanket (tokamak type)-trends in nuclear characteristics

    Publication Year: 1987 , Page(s): 16 - 27

    This paper briefly reports on the effects of openings (heating and pumping ducts) in a breeding blanket of a fusion reactor with tokamak physics on its nuclear characteristics. Predictions are based on 3-D Monte Carlo computations using the 3DAMC-VINIA subroutine complex operating without any numerical or geometrical simplifications; the ENDF/B library data are used in extenso. The objects under s... View full abstract»

  • Three-Dimensional Ray Tracing in Toroidal Stellarators

    We have applied a fully three-dimensional ray-tracing code to stellarators to examine the propagation of electromagnetic radiation near the electron cyclotron frequency in straight stellarators, toroidal stellarators, and tokamaks. The stellarators are simulated by using numerically computed vacuum magnetic fields and are assumed to have temperatures and densities which are constant on the flux su... View full abstract»

  • Plasma Performance of the Central Cell of a Cat-D Tandem Mirror Reactor

    Publication Year: 1987 , Page(s): 42 - 50

    A particle and power balance assessment of the central cell of a conceptual D-D tandem mirror reactor (TMR) is carried out using a two-dimensional (2-D) Fokker-Planck code and a zero-dimensional (0-D) simulation code. The two computational models produce excellent agreement except for the mean triton energy, the difference in which can be attributed to the fact that the 2-D code considers the long...

  • Multiarc Generator

    Publication Year: 1987 , Page(s): 51 - 55
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2807 KB)  

    A multiarc generator, comprised of stacked metal contact disks, has been tested. Arc formation occurred in the gaps between each cylindrically shaped contact piece during 3-to 30-kA discharges through various stacked disk configurations. Severe current limiting was demonstrated by stacked disks whose axial length was less than their diameter. Current extinction time periods for discharges through ... View full abstract»

  • Steady-State Orbitron Emissions

    Publication Year: 1987 , Page(s): 56 - 59

    The Orbitron maser has been operated at a pressure of 2 × 10-6 in the steady state. Electrons are supplied to the device by an oxide-coated tungsten cathode placed inside the cylindrical cavity. The plasma-free emission corresponded to harmonically related steady-state narrow lines. The fundamental (lowest frequency) line corresponds to a resonance in the cavity system, which could be observed wi... View full abstract»

  • ICRH Antenna Array Analysis and Resulting Problem of Generator Matching

    Publication Year: 1987 , Page(s): 60 - 69
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1587 KB)  

    A model for arrays of ion cyclotron resonance heating (ICRH) antennae is presented, each antenna being fed by a separate generator with its own tuning system. In view of wave spectrum shaping, arbitrary phasing is introduced between the generators. The array is analyzed in quasi-TEM modes, and its equivalent impedance matrix is derived. In the case of an antenna pair, we study the matching of both... View full abstract»

  • A New Method to Generate Square Pulses: Optoelectronic Switching in a Current Charged Transmission Line

    We demonstrated for the first time the operation of a new technique to generate square pulses of nanosecond duration at a 10-Hz repetition rate. This technique utilizes a current charged transmission line as an inductive storage element and a repetitive optoelectronic opening switch. View full abstract»

  • Temporally Resolved Spectroscopy of Laser-Induced Carbon Ablation Plasmas

    Publication Year: 1987 , Page(s): 73 - 77
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1922 KB)  

    Temporally resolved emission spectra (360-630 nm) of carbon ablation plasmas produced during laser hole boring by a 25-ns duration 1-J ruby laser pulse are presented. The emitted line radiation originates from, C+++ to C+ depending upon the time relative to the laser pulse. Plasma temperatures of 12-14 eV during the laser pulse to about 4 eV, 140 ns after the laser pulse are obtained by comparing ... View full abstract»
