Abstract
  • The SPIDER experiment (Source for the Production of Ions of Deuterium Extracted from an RF plasma) aims to qualify and optimize the full size prototype of the negative ion source foreseen for MITICA (full size ITER injector prototype) and the ITER Heating and Current Drive Injectors to be installed at ITER site. Both SPIDER and MITICA experiments are presently under construction at Consorzio RFX in Padova, with financial support from IO (ITER Organization), Fusion for Energy, italian research institutions and contributions from Japan and India Domestic Agencies. The vacuum vessel hosting the SPIDER beam source has been manufactured, tested and assembled on site during the last two years 2013-2014. The cylindrical vessel, about 6 m long and 4 m in diameter, is composed of two cylindrical modules and two torispherical lids at the ends. All the parts are made by AISI 304 stainless steel. The possibility of opening/closing the vessel for monitoring, maintenance or modifications of internal components is guaranteed by bolted junctions and suitable movable support structures running on rails fixed to the building floor. A large number of ports, about one hundred, are present on the vessel shell for diagnostic and service purposes. The main working steps for construction and specific technological issues encountered and solved for production are presented in the paper. Assembly sequences and tests on site (vacuum and functional tests) are furthermore described in detail, highlighting all the criteria and requirements for correct positioning and testing performances.
