Mark McCollum, Principal Research Engineer at the Holonyak Micro & Nanotechnology Lab at the University of Illinois at UrbanaChampaign, will guide you in how to think like a gas. So if you have gas at a pressure less than atmosphere, this a great opportunity to get in touch with your inner molecular identity. All the parts of vacuum systems will be discussed and may give you insight into why your vacuum chambers work (or don’t work) the way they do.
