About VacTran
VacTran facilitates the execution of laborious vacuum calculations, enabling rapid characterization and evaluation of vacuum system operational data and design alternatives.
It uses equations that have been widely published in textbooks and journal papers. These equations for gas flow, conductance, and gas loads have been taught to generations of practitioners in seminars, short courses, and schools.
Equations used in VacTran are applicable to many design problems, but have limitations. Complex problems are often better addressed by computational fluid dynamics and Monte Carlo methods, which are not included in VacTran. Please contact PEC if you need help assessing whether VacTran is an appropriate tool for your design.

In an increasingly competitive and economically constrained environment, inefficiency is no longer acceptable in many market sectors. Whether optimizing the production throughput of a coating system load lock or evacuating an accelerator ring of super conducting magnets, efficient and predictable design is a necessity.
VacTran can significantly reduce the calculation time and effort for designing vacuum systems, or for unrstanding the performance limitations in existing systems. VacTran was designed to ease the process of modeling a vacuum system. It was developed to solve common, real problems in industry and national labs. All suggestions for program improvement are gratefully acknowledged.
