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 alternative source of supply became necessary. Satisfactory pellets were produced without difficulty; however, it was determined that the conversion process could not be readily carried out in the existing NaF traps. Construction of a separate facility with provisions to handle the large quantities of hydrogen fluoride (HF) released during the process would be required to produce pellets at the rate needed. 1 fig., 2 tabs.

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 construction and operation viewpoint and is adequate for installation. According to both studies cited a tunnel of this size in reasonable geology will cost approximately $800 per linear foot. For the purposes of this analysis this is adopted as the standard tunnel.

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 pressures are compared with values obtained by other workers. The UH system retains broad, two-phase plateaus at temperatures to 1065/sup 0/C. The critical temperature must be above 1065/sup 0/C. 13 refs., 3 figs., 1 tab.

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.

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.

The laser system in the Laser Demonstration Facility is mounted on an array of 108 support columns. This milestone report describes the design, analyses, testing, fabrication, installation, and performance characteristics of these supports.

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 sector 19. Installation of the temporary stronger focusing is planned for summer 1985; full SLC FODO array focusing is scheduled for the following summer. This note presents the intermediate solution for sectors 11 through 19. In addition, the sector 10 quadrupole strengths required for matching beams into the doublet array are given. 1 figure, 4 tables.

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 very similar to that of WEN-1 to the northeast. Unknown faults in the granitic basement rocks, other than the Wendel fault, may be important channelways for the geothermal system. 4 refs., 3 figs.

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 data, both radiochemical and physiochemical, collected from this watershed.

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 conditions should result in the entrance to the fixed mask operating at a peak temperature of 105/sup 0/C with a peak thermal stress at 26% of yield.

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 results of astrophysical investigations in these fields are surveyed in this paper. 53 refs., 19 figs., 1 tab.
