Vacuum chambers used for space simulation often require large vacuum pumping systems or multiple, smaller vacuum pumping systems to accomplish evacuation in a reasonable time frame. Appreciable high vacuum pumping speed is required to complete evacuation and maintain vacuum at desired levels. There are numerous technical and economic challenges, as well as special design criteria that should be considered when selecting equipment and implementing techniques for large chamber evacuation. In this paper, selection criteria for rough vacuum and high vacuum equipment is reviewed with a focus on system sizing, system configuration, vacuum system operation and maintenance.
