Abstract
An effort has been made to reduce the main chamber neutral pressure during plasma operation by reducing the conductance from the volume beneath the divertor target to the main chamber. A method of sealing gaps between metal structures using Aramid cloth was developed. These seals resulted in a nearly 2-fold reduction in the main chamber pressure relative to sub divertor pressure
