4. Outgassing
   When a beam line or device is under vacuum, any oils or moisture in the device has a lower vapor pressure and evaporates. This is known as outgassing and spoils vacuum making it difficult for the device in question to pump down to operating vacuum levels. For this reason it is necessary to ensure th...
