| MOP045 | Electropolishing for EXFEL Cavities Production at Ettore Zanon SpA | 220 |
|
||
| A new horizontal electropolishing (EP) facility has been implemented by Ettore Zanon SpA for the series production of the EXFEL cavities produced by the company. According to EXFEL specification a bulk EP of at least 100 micron is the first step of the surface treatment for high performances. Particular attention has been dedicated to find the best configuration during qualification of the system. Correlation between process variables, RF tests at room temperature at Zanon and vertical RF tests at 2 K at DESY have been investigated and the Niobium removal optimized. The facility has been designed for industrial scope, in order to guarantee the required quality and production rate of 4 cavities per week. One of the most important aspects has been the system automation to have complete control of the process. | ||

In the Specification for XFEL Cavity preparation (R1) two different preparation sequences are presented. Ettore Zanon Company as one of the two companies contracted for XFEL cavity production and preparation has chosen the so called BCP flash cycle. To fulfill the requested work flow and quality of infrastructure and processes, the company set up a complete new infrastructure in refurbished fabrication halls. The layout of the facility, set up of work flow of preparation and test results of resonators processed by E.Zanon in their infrastructure will be reported.
