A microwiggler Free-Electron Laser at the Brookhaven Accelerator Test Facility

Description: We report the design and status of an FEL experiment at the Brookhaven National Laboratory Accelerator Test Facility. A 50 MeV high brightness electron beam will be utilized for an oscillator experiment in the visible wavelength region. The microwiggler to be used is a superferric planar undulator with a 0.88 cm period, 60 cm length and K = 0.35. The optical cavity is a 368 cm long stable resonator with broadband dielectric coated mirrors. 8 refs., 2 figs., 4 tabs.

Biomodal spontaneous fission

Description: Investigations of mass and kinetic-energy distributions from spontaneous fission have been extended in recent years to an isotope of element 104 and, for half-lives, to an isotope of element 108. The results have been surprising in that spontaneous fission half-lives have turned out to be much longer than expected and mass and kinetic- energy distributions were found to abruptly shift away from those of the lighter actinides, showing two modes of fission. These new developments have caused a re… more

The Brookhaven Accelerator Test Facility laser linac beam line

Description: We report here the low emittance beam transport line for laser acceleration experiments at the Brookhaven Accelerator Test Facility (ATF). In order to preserve the low emittance ({approximately} 10{sup -10} m-rad) 50 MeV electron beam, great care has to be paid to the higher-order effects. The low-emittance transport line consists of two parts; the first part performs and emittance selection, and the other part provides the possibility of energy selection and beam transport to the experimental … more

Operating point selection and burn stability control for the International Thermonuclear Experimental Reactor

Description: The selection and burn stability control of near-ignited operating points for the International Thermonuclear Experimental Reactor (ITER) are considered. It is suggested that high density (<T{sub e}>{sub n} {approximately} 6-10 keV) operating points are preferred from considerations of proximity to magnetohydrodynamic (MHD) stability limits, divertor operation, and fueling even though those points are intrinsically thermally unstable. Results from simple 0-D transport simulations suggest that t… more

Traveling-wave-tube simulation: The IBC (Interactive Beam-Circuit) code

Description: Interactive Beam-Circuit (IBC) is a one-dimensional many particle simulation code which has been developed to run interactively on a PC or Workstation, and displaying most of the important physics of a traveling-wave-tube. The code is a substantial departure from previous efforts, since it follows all of the particles in the tube, rather than just those in one wavelength, as commonly done. This step allows for nonperiodic inputs in time, a nonuniform line and a large set of spatial diagnostics.… more
