This model finds the plasma density distribution, n(x,y), and the positive electrical potential, {phi}{sub {infinity}}, between the surface of a planar magnetron cathode and a distant, uniform plasma. The intended application is for parameter studies of gas discharges in the range of 1--100 mTorr, which are often used as sputtering sources. The primary results are formulas which show how the spatial variation of the magnetic field, B(x,y), shapes the plasma density and influences the potential, as well as determining the magnitude of the magnetron current parallel to the cathode surface.

This engineering note provides the information used for purchasing two venturi flowmeters and one orifice flowmeter. One venturi and one orifice performance curve is provided along with the purchasing information. Performance data is also given to supplement the performance curves.

The raw calculations are attached as Appendix A. The calculations provide the analysis of the heat transferred while the LN{sub 2} subcooler is in use. In order to achieve an acceptable conclusion, the assumption of a fully developed thermal boundary layer was made. The hot fluid or the fluid condensing on the inside surface will determine the rate of heat transfer because A{sub o} = A{sub i} and h{sub o}A{sub o} >> h{sub i}A{sub i}. The conclusion drawn is to use a 1/2-inch OD copper tube wound approximately 8 times about an 8-inch diameter circle. There are also calculations concerning the size of the nitrogen supply and subcooler vent. The maximum mass flow rate was determined as 52.5 g/s and the sizing of the nitrogen supply and subcooler vent should be chosen accordingly.

The Petroleum Marketing Monthly (PMM) provides information and statistical data on a variety of crude oils and refined petroleum products. The publication presents statistics on crude oil costs and refined petroleum products sales for use by industry, government, private sector analysts, educational institutions, and consumers. Data on crude oil include the domestic first purchase price, the f.o.b. and landed cost Of imported crude oil, and the refiners` acquisition cost of crude oil. Refined petroleum product sales data include motor gasoline, distillates, residuals, aviation fuels, kerosene, and propane. The Petroleum Marketing Division, Office of Oil and Gas, Energy Information Administration ensures the accuracy, quality, and confidentiality of the published data in the Petroleum Marketing Monthly.
