Automating Pro/Engineer Using Trail Files and External Programs (open access)

Automating Pro/Engineer Using Trail Files and External Programs

Keyboard macros provide shortcuts to many repetitive command sequences in Pro/Engineer. They map any number of frequently used command sequences to user-selected keyboard keys. They may be nested within each other and may also include user keyboard entry within the macro. Another powerful feature of Pro/Engineer is adding menu options. Menu options may be added to any Pro/Engineer menu and is an effective way to graphically display keyboard macros to make them more accessible. Command sequences are mapped to a single user-defined menu option added to the bottom of any Pro/Engineer window. The '{at}setbutton' command added to the 'menu{_}def.pro' file specifies the commands to associate with added menu options. Menu options may also be used to execute non-Pro/Engineer commands. The associated command is linked to a menu option within Pro/Engineer's Utilities menu (in the Misc menu) and is issued whenever the menu option is selected. Such a feature is useful for adding menu options to start the Pro/Engineer User Guide utility, start a text editor from within Pro/Engineer, or perform system level actions. The '{at}setbutton{_}exec' command is used in the 'menu{_}def.pro' file for non-Pro/Engineer commands. A more detailed description of adding menu options can be found in the Pro/Engineer Fundamentals …

Calculation of the cross section for top quark production (open access)

Calculation of the cross section for top quark production

The authors summarize calculations of the cross section for top quark production at hadron colliders within the context of perturbative quantum chromodynamics, including resummation of the effects of initial-state soft gluon radiation to all orders in the strong coupling strength. In their approach they resume the universal leading-logarithm contributions, and they restrict the calculation to the region of phase space that is demonstrably perturbative. They compare the approach with other methods. They present predictions of the physical cross section as a function of the top quark mass in proton-antiproton reactions at center-of-mass energies of 1.8 and 2.0 TeV, and they discuss estimated uncertainties.

Coil end design for the LHC dipole magnet (open access)

Coil end design for the LHC dipole magnet

This paper describes the design of the coil ends for the Large Hadron Collider dipole magnets of the CERN European Laboratory for Particle Physics in Switzerland. This alternative to existing European designs was provided by Fermi National Accelerator Laboratory by agreement between CERN and the United States. The superconducting cable paths are determined from both magnetic and mechanical considerations. The coil end parts used to shape and constrain the conductors in the coil ends are designed using the developable surface, grouped end approach. This method allows the analysis of strain energy within the conductor groups, and the optimization of mechanical factors during the design. Design intent and implementation are discussed. Inner and outer coil design challenges and end analysis are detailed.

Compact tokamak reactors part 2 (numerical results) (open access)

Compact tokamak reactors part 2 (numerical results)

The authors describe a numerical optimization scheme for fusion reactors. The particular application described is to find the smallest copper coil spherical tokamak, although the numerical scheme is sufficiently general to allow many other problems to be solved. The solution to the steady state energy balance is found by first selecting the fixed variables. The range of all remaining variables is then selected, except for the temperature. Within the specified ranges, the temperature which satisfies the power balance is then found. Tests are applied to determine that remaining constraints are satisfied, and the acceptable results then stored. Results are presented for a range of auxiliary current drive efficiencies and different scaling relationships; for the range of variables chosen the machine encompassing volume increases or remains approximately unchanged as the aspect ratio is reduced.

Consequence analysis of an unmitigated NaOH solution spray release during addition to waste tank

Toxicological consequences were calculated for a postulated maximum caustic soda (NaOH) solution spray leak during addition to a waste tank to adjust tank pH. Although onsite risk guidelines were exceeded for the unmitigated release, site boundary consequences were below the level of concern. Means of mitigating the release so as to greatly reduce the onsite consequences were recommended.

Conventional and superconducting rf linac designs for the APT project (open access)

Conventional and superconducting rf linac designs for the APT project

The proton linac for APT (Accelerator Production of Tritium) will produce a nominal CW beam power of 130 MW at 1300 MeV. Two designs are currently under consideration. Reference design is composed entirely of normal-conducting (NC) copper accelerating structures, while an advanced-technology design employs superconducting Nb cavities above 217 MeV. Front-end accelerator for both concepts is a 100-mA NC linac. In this paper, the two APT linac designs are described and compared in terms of key factors, including power efficiency, beam loss control, machine availability and flexibility, and construction and operating costs.

Desalination with carbon aerogel electrodes (open access)

Desalination with carbon aerogel electrodes

An electrically regenerated electrosorption process known as carbon aerogel CDI was developed for continuously removing ionic impurities from aqueous streams. A salt solution flows in a channel formed by pairs of parallel carbon aerogel electrodes. Each electrode has a very high BET surface area and very low resistivity. After polarization, anions and cations are removed from electrolyte by the electric field and electrosorbed onto the carbon aerogel. The solution is thus separated into two streams, brine and water. Based on this, carbon aerogel CDI appears to be an energy-efficient alternative to evaporation, electrodialysis, and reverse osmosis. The energy required by this process is about QV/2, plus losses. Estimated energy requirement for sea water desalination is 18-27 Wh gal{sup -1}, depending on cell voltage and flow rate. The requirement for brackish water desalination is less, 1.2-2.5 Wh gal{sup -1} at 1600 ppM. This is assuming that stored electrical energy is reclaimed during regeneration.

Development of a telemetric heat stress monitor. Final report (open access)

Development of a telemetric heat stress monitor. Final report

Hazardous-materials workers and firefighters wear clothing that protects them from external hazards, but the sealed environment of a protective suit makes its wearer susceptible to heat stress. A prototype of the Telemetric Heat Stress Monitor (THSM) was developed at LANL to warn workers, and personnel monitoring the workers, of incipient heat stress by detecting the workers` elevated temperatures and heart rates. The purpose of this CRADA was to transfer the information and technology from LANL to the industrial partner, and to assist in the further development of a commercial THSM product. The THSM is the first extensive telemetric physiological monitor to be developed; previous monitors used wires between the sensors and the recording and display equipment. Developing a reliable, small, battery-powered, inexpensive telemetry system to share the RF spectrum with today`s proliferating wireless devices was a significant technical accomplishment.

Environmental assessment for consolidation of certain materials and machines for nuclear criticality experiments and training

In support of its assigned missions and because of the importance of avoiding nuclear criticality accidents, DOE has adopted a policy to reduce identifiable nuclear criticality safety risks and to protect the public, workers, government property and essential operations from the effects of a criticality accident. In support of this policy, the Los Alamos Critical Experiments Facility (LACEF) at the Los Alamos National Laboratory (LANL) Technical Area (TA) 18, provides a program of general purpose critical experiments. This program, the only remaining one of its kind in the United States, seeks to maintain a sound basis of information for criticality control in those physical situations that DOE will encounter in handling and storing fissionable material in the future, and ensuring the presence of a community of individuals competent in practicing this control.

Experimental Investigation of the Classical Rayleigh-Taylor Instability

The evolution of the Rayleigh-Taylor (RT) instability in a compressible medium has been investigated at an accelerating embedded interface and at the ablation front in a series of experiments on the Nova laser. The x-ray drive generated in a gold hohlraum ablatively accelerated a planar target consisting of a doped plastic pusher backed by a higher density titanium payload with perturbations placed at the plastic-Ti interface. The targets were diagnosed by face-on and side-on radiography. In previous work focusing on single mode perturbations, wavelengths as short as 10 m have been observed to grow strongly at the embedded interface. Here multimode perturbations consisting of either 2, 10 or 20 modes superposed in phase have been investigated.

Final report for tank 241-AN-102, grab samples 2AN-95-1 through 2AN-95-6 and 102-AN-1 through 102-AN-4

Ten grab samples (2AN-95-1, 2, 3, 4A, 5A; 102-AN-1, 2, 3(A), 3(B), and 4) and one field blank (2AN-95-6) were taken from tank 241-AN-102. In support of the safety screening program, total organic carbon and cyanide were performed as secondary analyses because the differential scanning calorimetry results exceeded the notification limit. These were compared to safety screening limits at a confidence level of 95%. Waste compatibility analyses were performed on the 3 supernate samples and the field blank from the latest sampling event. Results presented in the 45 day and in this report show that the waste in Tank 241-AN-1D2 has energetics greater than 480 J/g (dry) and total organic carbon > 3 wt%; however, with a moisture content > 17 wt%, the tank may be considered ``conditionally`` safe in accordance with the Data Quality Objective to Support Resolution of the Organic Complexant Safety Issue.

First positron annihilation lifetime measurement of Pu (open access)

First positron annihilation lifetime measurement of Pu

We have made the first measurement of defects in an aged sample of {delta} phase, Ga stabilized Pu, using positron annihilation lifetime spectroscopy. This measurement validates the procedure necessary to perform measurements on this highly toxic material and obtain data representative of sample conditions. Comparison of the positron annihilation lifetime analysis of the data with calculated values suggests that He filled vacancies or vacancy clusters dominate the defect population. Such defects are the necessary precursor to void growth and swelling. The evolution of defects resulting from the radioactive decay of Pu during its life in the stockpile is one of the unknown quantities affecting our confidence in predictions of the limit on stockpile components. Radiation damage leads to changes in the size and strength of metals studied for reactor and accelerator use and similar effects may be expected in Pu. The evolution of radiation produced vacancies into larger void structures and accompanying macroscopic swelling may occur in Pu at some age. A detailed understanding of the defects in self irradiated Pu is required to predict the time scale of void swelling and related radiation effects. 1 fig.

Hanford Cost Saving Plan

Fiscal Year (FY) 1995 challenged us to dramatically reduce costs at Hanford. We began the year with an 8 percent reduction in our Environmental Management budget but at the same time were tasked with accomplishing additional workscope. This resulted in a Productivity Challenge whereby we took on more work at the beginning of the year than we had funding to complete. During the year, the Productivity Challenge actually grew to 23 percent because of recissions, Congressional budget reductions, and DOE Headquarters actions. We successfully met our FY 1995 Productivity Challenge through an aggressive cost reduction program that identified and eliminated unnecessary workscope and found ways to be more efficient. We reduced the size of the workforce, cut overhead expenses, eliminated paperwork, cancelled construction of new facilities, and reengineered our processes. We are proving we can get the job done better and for less money at Hanford. DOE`s drive to do it ``better, faster, cheaper`` has led us to look for more and larger partnerships with the private sector. The biggest will be privatization of Hanford`s Tank Waste Remediation System, which will turn liquid tank waste into glass logs for eventual disposal. We will also save millions of dollars and avoid …
