Abstract

Problems with the oil cracking have been encountered in using the Edwards 9B3 diffusion pump with Edwards 200 grade pump fluid. These have been solved by using a different fluid, reducing the power to the heater without a loss of pumping speed and by constructing a more effective cold trap.
