Aspects of three field approximations: Darwin, frozen, EMPULSE

Description: The traditional approach used to study high energy beam propagation relies on the frozen field approximation. A minor modification of the frozen field approximation yields the set of equations applied to the analysis of the hose instability. These models are constrasted with the Darwin field approximation. A statement is made of the Darwin model equations relevant to the analysis of the hose instability.

Disruption angles

Description: This investigation has been stimulated by the question, to what extent beam disruption of two penetrating SLC bunches will modify the initial angular distribution of the incident beam, and whether the tails of the outgoing beam will be significantly enhanced and will lead to increased losses in the vicinity of the detector. We try to answer this question in three steps. 6 refs., 4 figs., 4 tabs.

Energy and angular distributions of radiation power from bending magnet and wiggler sources at a 6-GeV ring

Description: In order to design radiation ports and beam line components, it is essential to understand the distribution of power from a radiation source as a function of both the photon energy and the solid angle of emission. In this preliminary note, we assemble all the formula involved for the case of a bending magnet and a wiggler. Typical distributions are presented for the case of 6-Gev radiation.

An experiment to measure the electron neutrino mass using a cryogenic tritium source

Description: An experiment has been performed to determine the electron neutrino mass with the precision of a few eV by measuring the tritium beta decay energy distribution near the endpoint. Key features of the experiment are a 2 eV resolution electrostatic spectrometer and a high-activity frozen tritium source. It is important that the source have electronic wavefunctions which can be accurately calculated. These calculations have been made for tritium and the HeT/sup +/ daughter ion and allow determinati… more

Field-independent normalization of SSC Collider Ring costs

Description: The SSC Collider Ring represents the dominating cost element of the SSC project. The number of variables involved in optimizing the facility is very large so it is helpful to try to parameterize them in a way that allows a straightforward comparison of primary options. Cost information has been drawn from the Reference Designs Study supplemented by data from studies carried out by the Harza Engineering Company in Illinois. Various studies indicate that a 9' to 10' tunnel seems optimal from a co… more

Focusing upgrade for sectors 11 through 19

Description: In order to transport high current, single bunch beams to the SLC positron source for spring 1986 testing, it will be necessary to augment the strength of available focusing in sectors 11 through 19. We have decided to replace the sector doublet type QB quadrupoles with stronger type QE magnets. In conjunction with new Vax controlled power supplies, this sector 11 through 19 doublet lattice can be run at optimal settings for beam energies of several GeV up to the full SLC energy of 32 GeV by se… more

Galaxies and Saturn's rings: Gravitational analogues of nonneutral plasmas

Description: Orbit and collective dynamics in disk galaxies and in Saturn's rings are gravitational analogues of those occurring in nonneutral plasmas. The interesting problems for such ''gravitational plasmas'' are analogous to single-disk studies of transverse dynamics in particle beams. Of particular interest are various orbit-resonances with spiral density and bending waves in these disks which are analogous to electrostatic waves in nonneutral beam plasmas. The background physics, terminology and resul… more

Genocide Convention

Description: The Convention on the Prevention and Punishment of the Crime of Genocide has been a matter of pending business before the Senate since its transmittal to that body in 1949. On May 21, 1985, the Senate Foreign Relations Committee recommended that the Senate give its advice and consent to ratification of the Convention subject to eight conditions: two reservations, five understandings, and one declaration. This report examines the differing opinions on whether and under what conditions the Senat… more

GeoProducts WEN-2 well, Wendel-Amedee, California

Description: The GeoProducts WEN-2 well, drilled 2200 feet northwest of Wendel Hot Springs in Lassen County, California, penetrated 4330 feet (1320 meters) of Tertiary basalt flows and volcanoclastics. Production of 251/sup 0/F (122/sup 0/C) thermal fluids comes either from a fault or from intergranular permeability in a 570-foot thick quartzite conglomerate channel overlying the granitic basement rocks at a depth of 4900 feet. The chemistry, temperature and hydrostatic head of the resource in WEN-2 are ver… more

Groundwater protection EIS: Existing environment: Savannah River

Description: Per Groundwater Protection EIS commitments, a baseline of surface water hydrology and chemistry of each onsite stream is needed to define the existing environment of each watershed so that environmental impacts associated with the various waste site closure options can be assessed. This report summarizes the existing water quality of the Savannah River; lists the various waste sites encompassing this watershed; and summarizes the availability of surface water and floodplain sediment monitoring … more

Isotherms for the uranium-hydrogen system at temperatures of 700 to 1065/sup 0/C and pressures to 137. 89 MPa

Description: Pressure vs composition (P-C) isotherms for the UH system for temperatuers of 700 to 1065/sup 0/C and pressures to 137.89 MPa are shown. The sample was contained in a vessel concentric and located within a secondary vessel. Plateau pressure at 1065/sup 0/C is 700 atm. The single-phase region on the hydrogen-rich side starts at a H/U ratio of 2.35. Physical property measurements showed a thermal conductivity, k, value of 0.003 cal/cm sec K, R/sub c/ = 50. Experimentally determined plateau pressu… more

Pilot plant processing of sodium bifluoride to sodium fluoride pellets

Description: Sodium fluoride (NaF) traps in the PGDP purge cascade presently use NaF pellets to remove residual UF{sub 6} from the gas stream. These pellets are procured from ORGDP which converts sodium bifluoride pellets to NaF by thermal decomposition. Discussions of the possibility of no longer producing pellets at ORGDP, due to oven corrosion problems, led to a pilot plant test at PGDP. This test was designed to examine the feasibility of producing the NaF pellets at PGDP in the event that an alternativ… more

Reaction of Topopah Spring tuff with J-13 water: a geochemical modeling approach using the EQ3/6 reaction path code

Description: EQ3/6 geochemical modeling code package was used to investigate the interaction of the Topopah Spring Tuff and J-13 water at high temperatures. EQ3/6 input parameters were obtained from the results of laboratory experiments using USW G-1 core and J-13 water. Laboratory experiments were run at 150 and 250{sup 0}C for 66 days using both wafer-size and crushed tuff. EQ3/6 modeling reproduced results of the 150{sup 0}C experiments except for a small increase in the concentration of potassium that o… more

Thermal stress analysis of the SLAC fixed mask. Addendum

Description: X-ray beams emerging from the new SLAC electron-positron storage ring (PEP) can impinge on the walls of tangential divertor channels. A fixed mask made of OFHC copper is installed in the channel to limit wall heating. The mask is cooled with water flowing axially at 30/sup 0/C. Beam strikes on the mask cause highly localized heating in the channel structure. Analyses were completed to determine the temperatures and thermally-induced stresses due to this heating. The current design and operating… more
