| | Since several years electro-polishing (EP) of
superconducting resonators is one of the major
preparation techniques in use for high gradient
superconducting resonators. At DESY the EP facility is
operational since mid of 2003. About 150 resonators have
been polished in this infrastructure since. Typical process
data, a maintenance plan and reliability of components
installed in the DESY apparatus as well as actual RF test
results of resonators will be presented. For the XFEL
project the industrialization of the electro polishing
processes is started. A status report of the industrialization
will be given. | |

| | Under the contract RII3-CT-2003-506395 of the
European Union improvement on the electro-polishing
(EP) of multi cell resonators are made. Several methods
to improve resonator performances are studied.
Improvement of electrode shape, simulated by numerical
computer codes and test set ups are presented. With
respect to reproducible cavity performances and
industrialization of the EP process, a study for quality
control by acid management is started. An automated EP
system is developed at INFN Legnaro / Italy and within
the collaboration of Legnaro and DESY this automated
steering will be integrated into the DESY EP facility. We
will report on the status of the WP 5.2.2.and the progress
of the transfer of the automated EP. | |
