Introduction to Vacuum Technology - Learning Activity 9: Data for the Rate of Rise Curves with No Leak

In this video, published by Erie Community College, physics professor Elena Brewer conducts the pump-down process on a Rough Vacuum System Trainer (RVET) with an empty chamber and no leaks. Throughout the pump-down process, learners will document how long it takes for the atmospheric pressure in the chamber to reach 50 millitorrs and then collect data on the pressure as it rises again. Data collected from this video will be compared with two other pump-down datasets in activity nine to identify rough vacuum system leaks using rate-of-rise curves.

The video corresponds with lessons in a student lab manual and instructor guide that accompanies the Introduction to Vacuum Technology E-book. This textbook provides an introduction to vacuum technology and science, and features topics curated to the needs of technicians in a production environment. The guides include student questions and a data table corresponding to the video.

The video runs 7:51 minutes in length. The E-book, and related student and instructor guides, videos, and labs are available to view separately.
