            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
