For this report we have collected the papers presented by the HIFAR group at the IEEE Particle Accelerator Conference held in Washington, DC, on March 16-19, 1987, which essentially coincides with the end of the reporting period. In addition, we report on research to determine the cause of the failures of Re-X insulator that are used as the high-voltage feed-through for the electrostatic quadrupoles on MBE-4. This report contains papers on the following topics: LBL multiple beam experiments, pulsers for the induction linac experiment (MBE-4), HIF insulator failure, experimental measurement of emittance growth in mismatched space-charge dominated beams, the effect of nonlinear forces on coherently oscillating space-charge dominated beams, space-charge effects in a bending magnet system, transverse combining of nonrelativistic beams in a multiple beam induction linac, comparison of electric and magnetic quadrupole focusing for the low energy end of an induction-linac-ICF driver. Eight individual papers have been indexed separately. (LSP)

This study examined the use of group counseling and group discussion as a method of demonstrating changes on selected personality variables of first-year theology students. It was hypothesized that the subjects would become less dogmatic (more open-minded), motivated from a more internal locus of control, feel less anxious, and demonstrate greater creativity and self-concept following their participation in either group counseling or group discussion. Group counseling was hypothesized to be the best method for effecting changes. The subjects were first-year theology students at a southwestern theological seminary. These participants planned to work in some phase of ministry; several planning to be ordained as priests or to enter the deaconate. This study was based upon the premise that ministers often assume a counseling role and they therefore, need training in counseling skills and an opportunity to enhance their personal development. Group counseling and group discussion were explored as possible means to achieve these ends. Each of the five personality variables was measured on a pretest-posttest design. The subjects were tested prior to meeting in one of the two formats and tested again after fifteen hours of participation in one of the groups. A control group was also tested at these same …

This volume contains the proceeding and individual papers presented at the Fifth PTCOG meeting and International Workshop on Biomedical Accelerators. The meeting was divided into sessions on the biomedical aspects of therapy delivery, new biomedical accelerators, facilities, and beam localization and status report. Individual papers have been abstracted and indexed for the Energy Data Base.

The basic objective of the Heavy Ion Fusion Accelerator Research (HIFAR) program is to access the suitabilty of heavy ion accelerators as iginiters for Inertial Confinement Fusion (ICF). A specific accerelator techonolgy, the induction linac, has been studied at the Lawerence Berkeley Laboratory and has reached the point at which its viability for ICF applications can be assessed over the next few years. The HIFAR program addresses the generation of high-power, high-brightness beams of heavy ions, the understanding of the scaling laws in this novel physics regime, and the vadidation of new accelerator strategies, to cut costs. The papers in this report that address these goals are: MBE-4 mechanical progress, alignment of MBE-4, a compact energy analyzer for MBE-4, Cs/sup +/ injector modeling with the EGUN code, an improved emittance scanning system for HIFAR, 2-MV injector, carbon arc source development, beam combining in ILSE, emittance growth due to transverse beam combining in ILSE - particle simulation results, achromatic beam combiner for ILSE, additional elements for beam merging, quadrupole magnet design for ILSE, and waveforms and longitudinal beam-parameters for ILSE.

Phosphate ores contain elevated levels of natural radioactivity, some of which is released to the environment during processing or use of solid byproducts. The effect of radionuclides from Idaho phosphate processing operations on the local communities has been the subject of much research and study. The literature is reviewed in this report. Two primary radionuclide pathways to the environment have been studied in detail: (1) airborne release of volatile radionuclides, primarily /sup 210/Po, from calciner stacks at the two elemental phosphorus plants; and (2) use of byproduct slag as an aggregate for construction in Soda Springs and Pocatello. Despite the research, there is still no clear understanding of the population dose from radionuclide emissions, effluents, and solid wastes from phosphate processing plants. Two other potential radionuclide pathways to the environment have been identified: radon exhalation from phosphogypsum and ore piles and contamination of surface and ground waters. Recommendations on further study needed to develop a data base for a complete risk assssment are given in the report.

Human colony-stimulating factor-1 (CSF-1) was purified from the serum-free conditioned medium of a human pancreatic carcinoma cell line. The four-step procedure included chromatography on DEAE Sepharose, Con A Sepharose and HPLC on phenyl column and reverse-phase C-3 column. The purity of human CSF-1 was demonstrated by sodium dodecyl sulfatepolyacrylamide gel electrophoresis (SDS—PAGE) as a single diffuse band with a molecular weight (Mr) of 42,000-50,000 and was further confirmed by a single amino-terminal amino acid residue of glutamate. Under reducing conditions, purified CSF-1 appeared on SDS-PAGE as a single protein band with a Mr of 21,000-25,000 and concurrently lost its biological activity, indicating that human CSF-1 consists of two similar subunits and that the intact quaternary structure is essential for biological activity. When treated with neuraminidase and endo-8~D~N—acetylglucosaminidase D, the Mr of CSF-1 was reduced to 36,000-40,000 and to a Mr of 18,000-20,000 in the presence of mercaptoethanol.

The hypothesis that Dark Matter is made out of exotic particles is definite enough to be testable in a variety of ways. We review the first generation experiments looking for dark matter particles, using conventional techniques. They may find those particles and in any case will provide powerful constraints. We argue that in the long run, cryogenic detectors will have to be used for that type of physics, and since the European effort is covered by other speakers, we review the present developments in this area in the USA. 18 refs., 1 fig.

Solid ice-like mixtures of natural gas and water in the form of natural gas hydrated have been found immobilized in the rocks beneath the permafrost in Arctic basins and in muds under the deep water along the American continental margins, in the North Sea and several other locations around the world. It is estimated that the arctic areas of the United States may contain as much as 500 trillion SCF of natural gas in the form of gas hydrates (Lewin and Associates, 1983). While the US Arctic gas hydrate resources may have enormous potential and represent long term future source of natural gas, the recovery of this resource from reservoir frozen with gas hydrates has not been commercialized yet. Continuing study and research is essential to develop technologies which will enable a detailed characterization and assessment of this alternative natural gas resource, so that development of cost effective extraction technology.
