Vacuum Technology Explained – Part 4 of 4 – Ultra-high Vacuum

Vacuum is a required enabling condition for a huge range of scientific inquiries and industrial processes. The application of vacuum technology is complex, and requires basic understanding of the behavior of gas molecules in low-pressure conditions. Attend this webinar series to learn what you need to know.

Overview

Sub-atmospheric pressures are a necessity for a wide variety of processes affecting our daily lives, from the heat treatment of automobile components, to the manufacturing of microchips and screens that power our smart phones and computers, to the design and operation of analytical instruments that ensure the safety of our drinking water and food products.

Achieving the low pressure conditions required for these processes is not straightforward. For example, creating the vacuum necessary for particle physics research requires at least three, and often four, different vacuum pump technologies. Understanding how gas molecules behave at sub-atmospheric pressures is critical in designing effective vacuum environments, choosing the correct components and materials, and understanding maintenance requirements.

This webinar, the fourth in a four-part series, explains the process of generating, measuring, and maintaining ultra-high vacuum pressure (lower than approx. 10^-8 Torr). Ultra-high vacuum is a requirement for many scientific and industrial processes and can be difficult to achieve and maintain. Materials selection and pre-treatments such as baking become increasingly important. This session will include a brief review of concepts addressed in Sessions 2 and 3 (Rough and High Vacuum), and will cover applications requiring ultra-high vacuum, UHV pumps and gauges, materials, and troubleshooting UHV systems.
