Data and Plots for the dark and base leakage currents.

These graphs show the effect of cleaning the base on the Leakage Current. There is a measurable difference between a cleaned and uncleaned base. We also show the net Anode Current as a function of the difference between PMT+Base Current and the Base Alone Current.

Comparison before and after cleaning the bases (Postscript, GIF).
