Fourth Annual Christmas Lecture on Vacuum Science and Technology
The tradition of the Christmas lecture began in 1825 at the Royal Institution, in London, long before formal science education was available for the masses. Originated by Michael Faraday, the lectures focused on a single topic and were an opportunity to share the excitement of science with the learned and layperson alike. In this third annual Lesker U Live Christmas lecture we will focus on the wonders of 2,500 years of vacuum science and technology. Vacuum science has increasingly become an enabling technology for many of the incredible technological advances we enjoy in communications, display, medicine, energy conversion, transportation, and the exploration of the universe. In this fun and informative webinar, we will discuss and demonstrate some of the marvels of vacuum technology which make it so ubiquitous in our modern world. The session will also be peppered with live quizzes - just to make sure you are paying attention!

REGISTERVacuum Pumps for High Vacuum Applications
There is no one vacuum pump technology that can work from atmosphere down to high vacuum (pressures in the range of 10-6 Torr) and below. The achievement of low pressures in research or industrial vacuum systems requires a well-engineered combination of pumping technologies. The mechanisms to pump gases at high molecular densities are quite different from the techniques needed to move molecules once their numbers are substantially reduced. In this webinar we will discuss some of the measures required to achieve high vacuum and review the range of tools designed specifically to get to a low base pressure. Simple modeling will be introduced which will illustrate critical pressure ranges during pump down and system-specific characteristics that must be considered when determining pump down time and base pressures. The course will include details on the operating principles of rotary vane and dry scroll pumps, as well as turbomolecular, cryopumps, and oil-based diffusion pumps required to reach high vacuum.

REGISTERCleaning Components for High & Ultra-High Vacuum Service
Despite nearly 2,500 years of progress in vacuum science, much of the practice of cleaning components for vacuum service remains shrouded in folklore. Further, many of the materials used by pioneers in this area are now banned for environmental and health reasons. In this brief webinar, basic procedures to clean components for high and ultra-high vacuum use will be discussed including the preparation of a facility in which to do cleaning, personal protective equipment, green or sustainable materials for cleaning, and tests to verify the efficacy of a cleaning process. Materials to be cleaned will include metals such as 300 series stainless steel, aluminum, and copper, as well as glass and some ceramics. Approaches to mitigate the contamination of components and vacuum chambers will also be reviewed.

REGISTERDetecting 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.

REGISTERIntroduction 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. This special 1.5 hour introduction to Residual Gas Analysis (RGA) or partial pressure analysis will review the additional data than can be acquired as compared to 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.

REGISTERTests & Modeling of Vacuum System Performance
Understanding the performance of a vacuum system can provide insights into the quality and repeatability of processes done in vacuum. There are several factors which can result in large differentials between what a vacuum system was designed to accomplish, on paper, and what can be achieved empirically. In this 1-hour webinar we will discuss a few simple tests that can be used to effectively characterize the performance of a vacuum system. In addition, we will review the basic equations that relate ultimate pressure, gas load, chamber volume, cleanliness, and pumping speed. We will also discuss tactics to optimize vacuum system performance and take questions from participants on their specific vacuum system issues.
