| The Electro-Polishing (EP) process is the best candidate of final surface removal for the production of ILC cavities. Nevertheless, the broad distribution of the gradient caused by field emission is still a serious problem for the EP process. One candidate of sources for the field emission is the sulfur component which is produced during the EP process. We studied the effect of post-EP rinsing treatments with ethanol, detergent, and H2O2 in various conditions by a unique method. Moreover, we tried to test sponge cleaning as a new post- EP process. This article describes the results of series tests of these post-EP processes. |
