Introduction to Vacuum System Design

This class is an extension of our Introduction to Vacuum Science and System Design session. Vacuum system design is a process initiated with answers to several key questions, including the size and purpose of the process that will occupy the vacuum space, base pressure requirements, frequency of access through the vacuum barrier, and budget. Those criteria are the basis of several decisions to be made about materials, fabrication techniques, pumping system components, instrumentation, and infrastructure. In this course students will review the fundamentals of vacuum technology and step through the design process including examples of the consequences of materials selection, fabrication techniques, mechanical tolerances, and seal designs. Vacuum system performance, including pump down times based on pumping system alternatives, will also be discussed.

Duration: 1 Hour(s)

Introduction to Vacuum Science & System Design

This class is designed to introduce the student to basic concepts in vacuum technology and how they apply to system design and operation. Subjects covered include molecular density in vacuum, the ideal gas law, molecular flow in vacuum pressure regimes, characteristics of gas composition at various molecular densities, general principles of gas-solid interactions, vacuum pump technology, pressure sensors, leak detection and the impact of fundamental design decisions and operating practices on vacuum system performance. It is intended for people who are new to vacuum or may not have any formal training. It also provides a general review for those who have had some formal training in vacuum technology. The student should achieve a general understanding of vacuum technology as a foundation for further training in vacuum system design and thin film deposition.

Introduction to Residual Gas Analysis: Characterizing Partial Pressures

The precise characterization of pressure in a vacuum system requires the analysis of the residual gases that are present. Residual Gas Analysis (RGA) or partial pressure analysis provides substantially more data than can be acquired by a simple measure of total pressure. The system uses atomic mass units to distinguish atomic and molecular gases in addition to gas compounds such as CO2, fingerprints, pump fluids, and other hydrocarbons. In this webinar the broad range of useful information, including trends in gas composition, outgassing rate, leak detection, and system cleanliness derived from RGA will be discussed. Principles of operation, pressure limits, sensitivity, mass ranges, spectra interpretation, detector placement, start-up and shutdown will also be discussed.

Duration: 1.5 Hour(s)

Detecting Leaks in Vacuum Systems

Leaks are the bane of vacuum systems. Leaks are one of the principal causes that inhibit the achievement of optimal base pressures. There are several approaches available to detect leaks of various sizes which do not involve expensive leak detection tools. In this course the methods to quantify leaks and a general approach to detection will be presented. In addition, specific techniques to detect leaks in rough, medium, high and ultra-high vacuum will be detailed. The use of helium-based leak detectors as well as the use of residual gas analysis for finding very small leaks will also be highlighted.

Vacuum Pumps for Ultra High Vacuum Applications - Part 2

The achievement of ultra-high vacuum pressures in a research or industrial system requires some extraordinary measures. Accordingly, the vacuum pumps required to reach 10-9–10-12 Torr are also extraordinary. In this second session on pumping systems for ultra high vacuum we will build on the system requirements and heroic measures discussed in session #1 and review the range of tools designed specifically to remove or trap the last few remaining gases present at these very low pressures. The course will include details on the operating principles of sputter ion pumps, sublimation pumps, and other techniques that can be employed to reach and maintain UHV pressures.
