A getter screen consists of a cylinder of length l = 0.3m, diameter d=0.25m and its circular based plate. The getter screen is cooled with liquid nitrogen and coated completely with deposited titanium providing a constantly fresh surface. Sticking probability s=1 for N2 and mean thermal velocity = 470m/s. Find the pumping speed.
