Commissioning of polarized-proton and antiproton beams at Fermilab (open access)

Commissioning of polarized-proton and antiproton beams at Fermilab

The author described the polarized-proton and polarized-antiproton beams up to 200 GeV/c at Fermilab. The beam line, called MP, consists of the 400-m long primary and 350-m long secondary beam line followed by 60-m long experimental hall. We discuss the characteristics of the polarized beams. The Fermilab polarization projects are designated at E-581/704 initiated and carried out by an international collaboration, Argonne (US), Fermilab (US), Kyoto-Kyushu-Hiroshima-KEK (Japan), LAPP (France), Northwestern University (US), Los Alamos Laboratory (US), Rice (US), Saclay (France), Serpukhov (USSR), INFN Trieste (Italy), and University of Texas (US).

D0 Cryogenic In-Line Filters (open access)

D0 Cryogenic In-Line Filters

The DO cryogenic system utilizes liquid argon (serving as the detector ionizing medium) and liquid nitrogen (refrigerant for the argon). In order to keep these fluids pure and minimize the likelihood of plugged instrumentation due to contamination, in-line filters will be installed on the following lines (see Cryogenic Flow Diagram, drawing 3740-ME-222394): 445LN, 412LN, 447LA, 427LA. and 422GA. The lines referred to by these labels are argon dewar LN2 supply, cryostat LN2 supply, LAr dewar fill/drain line, cryostat LAr fill/drain line, and dewar-to-cryostat argon gas line, respectively. Five filters are required. As of this writing, one has been built and tested. The others are to be identical in concept and construction.

Dried plutonium nitrate decontamination using HNO{sub 3} or Freon 113 (open access)

Dried plutonium nitrate decontamination using HNO{sub 3} or Freon 113

A request was made of the Separations Technology Laboratory to perform tests to determine the relative effectiveness of Freon 113 and 18% (3.15M) nitric acid on removing dried plutonium nitrate from Hypalon{reg_sign} gloves destined for use in F B-Line. Freon 113 was very inefficient for removing dried plutonium nitrate under conditions of moderate agitation of the liquid in contact with the dried compound. Nitric acid proved to be an excellent agent for decontaminating purposes for both the gloves and for the Pyrex glass. In tests conducted on the glass or on the gloves on which dried plutonium nitrate had not been removed by Freon 113, followup with nitric acid efficiently removed the residual plutonium nitrate. Tests were also conducted to give some measure of the resistance of the Hypalon glove to continuous contact with 18% HNO{sub 3} or with Freon 113. Following two weeks` immersion, there was little physical difference noted from the starting material, except the glove piece immersed in the Freon underwent an 8% weight gain.

Education Proposals in Trade Competitiveness Legislation (open access)

Education Proposals in Trade Competitiveness Legislation

Improvement on America's competitive position in international trade is one of the major issues confronting the 100th Congress. Most legislative proposals have included provisions for increasing the funding levels for Federal education programs, expanding current programs, or authorizing new programs. The primary goal is to improve the productivity of the Nation's workers by raising the skill level of the workforce. Discussions about education's role i n addressing the competitiveness issue have included the contribution of education to productivity growth, comparisons of the educational achievement of American school children with that of their peers in other nations , the educational needs of illiterate adults , and the role of technology in education.

Electromagnetic pair production in relativistic heavy-ion collisions (open access)

Electromagnetic pair production in relativistic heavy-ion collisions

We survey the production of electron, muon and tauon pairs in collisions between nuclei at ultra-relativistic energies. Such studies enhance our understanding of the role of the vacuum in field theory, and provide essential input for several experimental programs. A variety of models for the nuclear and nucleon form factors have been considered, revealing some degree of sensitivity to assumptions about sub-nuclear structure. We predict that the cross sections, even at high invariant masses and transverse momenta, are large on hadronic scales, and should act as useful probes of nuclear and nucleon form factors. 21 refs., 5 figs.

The internal bunch coordinate monitor (IBCM) (open access)

The internal bunch coordinate monitor (IBCM)

An instrument has been developed and installed at the AGS for recording the transverse motion of each rf bunch. It can be operated from any node of the Apollo control system. A preliminary version of this report has appeared elsewhere. Appendix A is an instruction manual. Two digitizers, running off the same 100 MHz clock, sampled the output of either a horizontal or vertical pick-up electrode (PUE) pair. The coordinate of each rf bunch was calculated each time it passed the PUEs during a 320 microsecond interval. Thus, the motion of each bunch could be followed during this interval. Subsequent analysis computed the Fourier transform of this motion. Bunch motion has been studied at several times during the AGS cycle: the betatron oscillations induced by the tune meter's vertical kick have been seen, and their Fourier analysis gives results consistent with the tune meter; at transition, the effect of the radial kick on each bunch has been observed; coupled-bunch oscillations have been studied; and instabilities produced by high intensities have been observed. 6 figs., 1 tab.

Localized corrosion and stress corrosion cracking of candidate materials for high-level radioactive waste disposal containers in the US: A literature review (open access)

Localized corrosion and stress corrosion cracking of candidate materials for high-level radioactive waste disposal containers in the US: A literature review

Container materials may undergo any of several modes of degradation in this environment, including: undesirable phase transformations due to lack of phase stability; atmospheric oxidation; general aqueous corrosion; pitting; crevice corrosion; intergranular stress corrosion cracking (IGSCC); and transgranular stress corrosion cracking (TGSCC). This paper is an analysis of data from the literature relevant to the pitting, crevice corrosion, and stress corrosion cracking (SCC) of these alloys. Though all three austenitic candidates have demonstrated pitting and crevice corrosion in chloride-containing environments, Alloy 825 has the greatest resistance to these forms of localized attack. Both types 304L and 316L stainless steels are susceptible to SCC in acidic chloride media. In contrast, SCC has not been documented for Alloy 825 under comparable conditions. Gamma irradiation has been found to enhance SCC of Types 304 and 304L stainless steels, but it has no detectable effect on the resistance of Alloy 825 to SCC. Furthermore, while microbiologically induced corrosion effects have been observed for 300-series stainless steels, nickel-based alloys such as Alloy 825 seem to be immune to such problems. Of the copper-based alloys, CDA 715 has the best overall resistance to localized attack. Its resistance to pitting is comparable to that of CDA 613 …

Muon fluence measurements during the 1987-1988 fixed-target run (open access)

Muon fluence measurements during the 1987-1988 fixed-target run

Muon fluence and dose equivalent have been observed at the Fermilab site boundary for the MC, MW, and NM beam lines. For MC and MW, the 1987 annual dose equivalents of 2.9 and 1.2 mrem respectively, are less than the 10 mrem site boundary goal. For the new NM beam line, on the other hand, the observed value 13.1 mrem exceeded this operational goal. Indeed, it was this observation that necessitated the additional ''spoilers'' downstream of the E665 experiment. With these magnets in place, however, the 10 mrem goal should not be in jeopardy for future runs.

Optical simulation for imaging reconnaissance and intelligence sensors OSIRIS: High fidelity sensor simulation test bed; Modified user`s manual

The OSIRIS program is an imaging optical simulation program which has been developed to predict the output of space-borne sensor systems. The simulation is radiometrically precise and includes highly realistic laser, atmosphere, and earth background models, as well as detailed models of optical components. This system was developed by Rockwell Power Services for the Los Alamos National Laboratory. It is based upon the LARC (Los Alamos Radiometry Code, also by Rockwell), and uses a similar command structure and 3d coordinate system as LARC. At present OSIRIS runs on the Cray I computer under the CTSS operating s stem, and is stored in the OSIRIS root directory on LANL CTSS mass storage.

PACER Revisited (open access)

PACER Revisited

This paper discusses a modified version of the PACER concept for power and nuclear material production, which changes the working fluid in the cavity from steam to the molten salt, LiF + BeF/sub 2/. In the PACER concept, a 20-kt peaceful nuclear explosion is contained in a cavity about 200 m in diameter, filled with 200 atm of 500/degree/C steam. Energy from the explosion is used to produce power, and the neutrons are used to produce materials such as /sup 233/U, Pu, /sup 60/Co, and T. The present idea is to modify the PACER concept in three ways, to improve the practicality, predictability, and safety of power production from this technology and thus improve public acceptance of this power source. These improvements are line the cavity with steel; replace the steam with molten salt; and reduce the explosive yield to about 2 kt. This concept is the only fusion power concept where the underlying technology is proven and in hand today. 9 refs., 3 figs., 1 tab.

A review of experimental progress in gluonia (open access)

A review of experimental progress in gluonia

There has been considerable progress in gluonia investigations and their analysis. As requested by the Convenor, Rich Galik, I will cover the highlights of various conference papers and related work in an integrated manner which incorporates a review of the present state of glueballs (gluonia) to the extent space limitations allow. There are four general methods of searching for glueballs: J//psi/ radiative decay (iota, theta, xi(2.2)); OZI violating (g/sub T/, g/sub T/', g/sub T//double prime/); hadronic interaction pattern recognition of extra isosinglet states in addition to q/bar q/ nonets, iota, G, S*', g/sub s/; and double Pomeron exchange. These will be reviewed. 4 refs., 4 figs.

Seismic monitoring of the June, 1988 Salton Sea Scientific Drilling Program flow/injection test (open access)

Seismic monitoring of the June, 1988 Salton Sea Scientific Drilling Program flow/injection test

The purpose of the seismic monitoring project was to characterize in detail the micro-seismic activity related to the Salton Sea Scientific Drilling Program (SSSDP) flow-injection test in the Salton Sea Geothermal Field. Our goal was to determine if any sources of seismic energy related to the test were observable at the surface. We deployed our recording stations so that we could detect and locate both impulsive microearthquakes and continuous seismic noise energy. Our network, which was sensitive enough to be triggered by magnitude 0.0 or larger events, found no impulsive microearthquakes in the vicinity of the flow test in the 8 month period before the test and only one event during the flow test. This event has provided the opportunity to compare the detection and location capabilities of small networks and arrays in a geothermal environment. At present, we are carefully scanning all of the data that we collected during the flow test for evidence of anomalous seismic noise sources and for impulsive events smaller than the network detection threshold (magnitude 0.0). 8 refs., 4 figs.

Tank evaluation system shielded annular tank application

TEST (Tank Evaluation SysTem) is a research project utilizing neutron interrogation techniques to analyze the content of nuclear poisons and moderators in tank shielding. TEST experiments were performed on an experimental SAT (Shielded Annular Tank) at the Rocky Flats Plant. The purpose of these experiments was threefold: (1) to assess TEST application to SATs, (2) to determine if Nuclear Safety inspection criteria could be met, and (3) to perform a preliminary calibration of TEST for SATs. Several experiments were performed, including measurements of 11 tank shielding configurations, source-simulated holdup experiments, analysis of three detector modes, resolution studies, and TEST scanner geometry experiments. 1 ref., 21 figs., 4 tabs.
