A technique to determine the outgassing occurring within a vacuum system as a continuous function of time and to analyze the resulting curve for information on the source and nature of the outgassing is described. Applications in determining the optimum combination of such parameters as temperature, time, materials, restrictions, and pumps on hermetic volume exhaust and cellulose dehydration are discussed. This technique was also used to study such phenomena as the outgassing characteristics of insulating materials and vacuum gages, the flow of gasses through orifices and short tubes, and the gettering action of various materials A digital computer and data reduction facilities were incorporated to eliminate the detailed hand calculations and plotting. This has resulted in a rapid and inexpensive method for the study of vacuum engineering problems. (auth)
