Abstract : The capture coefficients were determined for carbon dioxide, nitrogen, and argon on a flat cryopanel. The gas flow rates studied varied between 0.021 torr liters per second and 0.433 torr liters per second. For flow rates greater than 0.05 torr liters per second the capture coefficients for each of the gases decreased with an increasing flow rate. It was found that the caputre coefficients of carbon dioxide also depend upon the cryopanel temperature. Above 0.05 torr liters per second the capture coefficients decreased with an increasing cryopanel temperature. (Author)
