Abstract
We are building an apparatus to conduct electron-atom scattering experiments. It is necessary for the scattering to occur in a vacuum so that no atoms or other particles are able to interfere with the scattered electrons before they arrive at the detector. Here we provide a detailed description of the vacuum system for the apparatus. The vacuum system includes an airtight chamber in which the scattering will take place, a turbo pump and a mechanical rotary pump in order to pump the system down (~10-7 Torr), and an ion gauge and gauge controller to measure the pressure. We also detail the interlock system used to shut down the turbo pump and pressure-sensitive equipment if the pressure within the chamber gets too high so that no equipment is damaged.
