61/1-009 - Room C (CERN)

Alejandro Castilla Loeza (Lancaster University (GB))

Visit of Research Instruments to CERN for a detailed discussion on the lessons learned from the manufacturing of two DQW pre-series bare cavities, mitigation measures, and following steps in views of the series production. There will be punctual intervention from CERN experts, visits on site to the relevant installation and presentations of RI.
