Photon Spectrum From Bremsstrahlung (open access)

Photon Spectrum From Bremsstrahlung

Abstract: The number of photons of given energy radiated in Bremsstrahlung collision of electrons with nuclei is calculated relativistically. Expansions are obtained for energies small to mc-squared. The photon spectrum is averaged over a Maxwell distribution for the electrons. Numerical results are included.

Backmixing in Pulse Columns II, Experimental Values and Effect of Several Variables (open access)

Backmixing in Pulse Columns II, Experimental Values and Effect of Several Variables

Seven runs were made with the system Penn. Ref. Co. "Supersol" (dispersed) water (continuous) to investigate the effects of pulse frequency, amplitude plate spacing, volume flow ratio, and throughput on backmixing, using the technique of continuous injection of a tracer solution into the packed section. Backmixing was found to be surprisingly insensitive to all the above variables over the range studied with the exception of pulse amplitude and continuous phase flow rate, showing greatest dependence on the later. Backmixing increased with decreasing continuous phase flow rate and increased with pulse amplitude.

Functional Testing and Operating Manual for Consolidated Helium Leak Detector, Model 24-101A (open access)

Functional Testing and Operating Manual for Consolidated Helium Leak Detector, Model 24-101A

A pile gas leak detection system consisting of a purchased mass spectrographic type of helium detector, a long sampling line for use in remote or relatively inaccessable locations, a pump to pull a continuous sample of gas from the tip of the probe to the detector, and a rotameter to measure the gas flow rate in the sampling line has been developed, calibrated, operationally tested. The system is practical for use in locating all pile gas leaks larger than about 0.1 cubic foot per hour.

Gas Plated Coatings on Metals and Alloys : Progress Report No. 1 (open access)

Gas Plated Coatings on Metals and Alloys : Progress Report No. 1

The object of this project is to conduct studies on the coating of metals and alloys by the gas plating process. Coatings to be studied consist of chromium on copper; alloys of nickel chromium on copper; molybdenum on stainless steel and Inconel; chromium on stainless steel and Inconel; and tungsten and molybdenum and their carbides on stainless steel and Inconel.
