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. 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.
Duration: 1.5 Hour(s)

REGISTERTests and 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.

REGISTERPressure Control for Vacuum Systems, Featuring Mass Flow Controllers
The control of pressure in vacuum systems can be critical to the achievement of process parameters necessary for certain vacuum-enabled processes. While application like thin film deposition by thermal and e-beam evaporation are enhanced by extremely low operating pressures, other techniques, like sputtering and certain chemical processes, can only be accomplished at pressures which are significantly HIGHER than the base pressure achievable by a high vacuum pumping system. The control of pressure in vacuum can be achieved by a variety of techniques. In this webinar several techniques will be described, with examples, to control operating pressure in vacuum. Both manual and automated techniques will be discussed as they apply to various applications.

REGISTERFourth 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!
