Notes:
The experimental reactor cell designed and developed for the growth of films and crystals by closed cell physical vapor transport on the Space Shuttle Orbiter is discussed. The cell design has been proven by over 60 experiments, including 18 on two space flights, to be very satisfactory from the standpoints of minimal power use at operating temperatures of 400 °C, mechanical vibration resistance and approximation to ideal steady-state growth conditions. The performance realized is closely related to the assembly and cell preparation procedures which affect internal outgassing into a critical vacuum insulation region. The results of thermal performance studies of the cell as a function of this gas composition and pressure, as well as actually measured power and temperature relationships occurring during ground control and flight thin film growth experiments are presented. The cell design is presented in detail and the important aspects of the cell preparation and assembly identified.
