Cleaning Components for 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.

Annual Christmas Lecture on Vacuum Science & 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!

Dry Vacuum Pumps for Reduced Contamination & the Oil-Free Production of Vacuum

Oil contamination introduces an unwanted variable in vacuum processes which can ruin research results and create the need for an extensive cleaning of a vacuum system. Contamination resulting from backstreamed vapors from oil-sealed vacuum pumps is increasingly an issue that must be mitigated to produce pristine vacuum environments. Removal of oil contamination may require complete disassembly and other heroic measures to renew all vacuum-facing surfaces and return a system to pristine condition. A range of oil-free vacuum pumps have been developed for rough, high, and ultra-high vacuum. These pumps, including dry scroll, screw and roots pumps, for rough vacuum, as well as turbomolecular, cryopump, and various solid-state getters, for high and ultra-high vacuum, provide extremely clean routes for the production of vacuum. In this brief introduction, the specific pumping mechanisms, advantages, and drawbacks, of various dry pumping technologies will be discussed and a few example applications will be featured.
