VACTRAN

Computer Software for modeling vacuum system parameters, performing vacuum calculations, and compiling and generating vacuum-related databases Software for modeling vacuum system parameters, namely pumps, conductances, permeation, and out-gassing; computer software for performing vacuum calculations, namely vessel pressure versus time calculations, gas load versus time calculations, and delivered throughput versus time calculations; computer software for compiling and generating vacuum-related databases, namely common permeation and out gassing materials, pipes and o-rings
