Abstract
The pressure drop method was used to experimentally determine the capture coefficients of nitrogen gas on a flat cryopanel maintained at a temperature of 25°K. The capture coefficients for 300°K nitrogen varied from a maximum of 0.70 for low system gas loads to a minimum of 0.10 for high system gas loads.
