The Beam Break-Up Numerical Simulator

Description: Beam Break-Up (BBU) is a severe constraint in accelerator design, limiting beam current and quality. The control of BBU has become the focus of much research in the design of the next generation collider, recirculating and linear induction accelerators and advanced accelerators. Determining the effect on BBU of modifications to cavities, the focusing elements or the beam is frequently beyond the ability of current analytic models. A computer code was written to address this problem. The Beam Br… more

Charge states of high Z atoms in a strong laser field

Description: We present a numerical solution of the Thomas-Fermi atom in the presence of a static electric field as a model of the adiabatic response of a heavy atom in the presence of a strong laser field. In this semiclassical approach, we calculate the resulting charge state of the atom and its induced dipole moment after the field is turned on. Due to the scaling properties of the Thomas-Fermi approach, the resulting total atomic charge and dipole moment can be expressed as a universal function of the f… more

Cryosorption of helium on argon frost TFTR (Tokamak Fusion Test Reactor) neutral beamlines

Description: Helium pumping on argon frost has been investigated on TFTR neutral beam injectors and shown to be viable for limited helium beam operation. Maximum pumping speeds are {approximately} 25% less than those measured for pumping of deuterium. Helium pumping efficiency is low, > 20 argon atoms are required to pump each helium atom. Adsorption isotherms are exponential and exhibit a two-fold increase in adsorption capacity as the cryopanel temperature is reduced from 4.3 K to 3.7 K. Pumping speed was… more

The effects of photon spectrum and variable thermal conductivity on the distribution of temperature in an inclined plate crotch absorber

Description: Absorption of photons in a metal is varied up to the photon energy spectrum. For example, larger wavelength photons generally can be more easily absorbed when they pass through an absorber while shorter ones tend to penetrate. This spectral variation of photon energy absorption takes place angularly due to the angular variation of the synchrotron radiation power. In this note, the effects of photon spectrum have been investigated for the thermal analysis of crotch absorbers. In addition, the ef… more

Electron crystallography of PhoE porin, an outer membrane, channel- forming protein from E. coli

Description: One approach to studying the structure of membrane proteins is the use of electron crystallography. Dr. Bing Jap has crystallized PhoE pore-forming protein (porin) from the outer membrane of escherichia coli (E. coli) into monolayer crystals. The findings of this research and those of Jap (1988, 1989) have determined these crystals to be highly ordered, yielding structural information to a resolution of better than 2.8 angstroms. The task of this thesis has been to collect and process the elect… more

Energy confinement time and electron density profile shape in TFTR (Tokamak Fusion Test Reactor)

Description: The electron density profiles of intense deuterium neutral-beam- heated plasmas (P{sub tot}/P{sub ohm} {gt} 10) are characterized as a peakedness parameter (F{sub ne} = n{sub eo}/{l angle}n{sub e}{r angle}) in the Tokamak Fusion Test Reactor (TFTR). The gross energy confinement time ({tau}{sub E} = E{sub tot}/P{sub tot}) at the time of maximum stored energy is found to be a weak function of the plasma current and total heating power but depends strongly on the peakedness parameter.
