Chimney Open Issues

Description: In the process of developing a design for the design report, many side questions or comments arose which were not completely answered or investigated because the work was outside the scope of developing a base design. I have pored over my meeting notes and tried to list all such chimney 'open issues' in this engineering note.

Control Dewar Secondary Vacuum Container

Description: This engineering note provides background information regarding the control dewar secondary vacuum container. The secondary vacuum container has it's origin with the CDP control dewar design. The name secondary vacuum container replaced the CDP term 'Watt can' which was named after Bob Watt (SLAC), a PAC/DOE review committee member who participated in a review of CDP and recommended a secondary vacuum enclosure. One of the most fragile parts of the control dewar design is the ceramic electrical… more

Control Dewar Subcooler Heat Exchanger Calculations

Description: The calculations done to size the control dewar subcooler were done to obtain a sufficient subcooler size based on some conservative assumptions. The final subcooler design proposed in the design report will work even better because (1) It has more tubing length, and (2) will have already subcooled liquid at the inlet due to the transfer line design. The subcooler design described in the 'Design Report of the 2 Tesla Superconducting Solenoid for the Fermilab D0 Detector Upgrade' is the final de… more

Control of movement in an arbitrary polygonal terrain

Description: Efficient algorithms are presented for coordinated movement of semi-automated, computer-generated forces in a command hierarchy. At each level in the hierarchy, units move toward a goal, selected at a higher level, along paths which combine maintenance of a desired formation with minimization of a penalty integral -- some weighted combination of factors such as time, fuel, exposure, attrition, etc. Topics considered are the representation of terrain as a convex polygonal mesh, generalization of… more

D0 Solenoid Upgrade Project: D0 Solenoid Current Leads

Description: This engineering note documents information gathered and design decisions made regarding the vapor cooled current leads for the D-Zero Solenoid. The decision was made during design group meetings that the D-Zero Solenoid, rated at 4825 amps, should use vapor cooled current leads rated at 6000 amps. CDF uses 6000 amp leads from American Magnetics Inc. (AMI) and has two spares in their storage lockers. Because of the spares situation and AMI's reputation, AMI would be the natural choice of vendor… more

Development of advanced NO[sub x] control concepts for coal-fired utility boilers

Description: The complete CombiNO[sub x], process has now been demonstrated at a level that is believed to be representative of a full-scale boiler in terms of mixing capabilities. A summary of the results is displayedin Figure 5-1. While firing Illinois Coal on the Reburn Tower, Advanced Reburning was capable of reducing NO[sub x], by 83 percent. The injection of methanol oxidized 50--58 percent of the existing NO to N0[sub 2]. Assuming that 85 percent of the newly formed N0[sub 2] can be scrubbed in a liq… more

Development of vanadium-phosphate catalysts for methanol production by selective oxidation of methane

Description: Amax R D will perform laboratory scale development of a promising, practical catalyst for the selective oxidation of methane to methanol. The primary component of this catalyst is vanadium-phosphate (VPO) which has shown good activity and selectivity in the partial oxidation of n-butane and propane but has not been studied in detail for methane oxidation. The goal of the project is to develop a catalyst which allows methane oxidation to methanol to be conducted at high conversion and selectivit… more

An Efficient Microwave Power Source: Free-electron Laser Afterburner

Description: A kind of microwave power source, called a free-electron laser afterburner (FEL afterburner) which consists of a free-electron laser buncher and a slow-wave output structure sharing a magnetic wiggler field with the buncher, is proposed. The buncher and the slow-wave structure can operate in either a travelling-wave state or a standing-wave state. In the buncher, the wiggler field together with the radiation field makes an electron beam bunched, and in the slow-wave structure the wiggler field … more

Engineering development of advanced physical fine coal cleaning for premium fuel applications. Quarterly technical progress report No. 4

Description: This project is a major step in the Department of Energy`s program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effective replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These conce… more

Errors when shock waves interact due to numerical shock width

Description: A simple test problem proposed by Noh, a strong shock reflecting from a rigid wall, demonstrates a generic problem with numerical shock capturing algorithms at boundaries that Noh called excess wall heating.'' We show that the same type of numerical error occurs in general when shock waves interact. The underlying cause is the non-uniform convergence to the hyperbolic solution of the inviscid limit of the solution to the PDEs with viscosity. The error can be understood from an analysis of the a… more

Fundamental studies of coal liquefaction

Description: The results for the control run for a single particle are shown in Figure 1. The figure, which includes other thermolytic data for Illinois No. 6 coal, shows that the particle was stable in size to around 440[degree]C. At that point it contracted very rapidly to about half its size over the next 15[degrees]. Also shown are data for the same coal from SRI's field ionization mass spectrometer (FIMS), in which case a sample of the coal is heated at 2.5[degrees]C/min from ambient to 500[degrees]C a… more

The action continues in Figure 4 where the particle contracts to about half its initial size over a 45 sec period as the temperature, increases from 424{degrees}C to 430{degrees}C, at which point the contraction stops… more
