The Transmission Line for the SPIDER Experiment: From design to installation

An air insulated design of the TL, coping with the large dimensions required to host ISEPS diagnostic and power cables and duly screened against Electromagnetic Interferences (EMI), has been conceived. The paper reports on the construction solutions developed by the Manufacturer to meet the design indications and requirements of the technical specification for such unconventional device. Moreover, the factory type tests to validate the design and release the manufacturing of the overall TL are described. Finally, the paper reports on the on-site installation and commissioning activities for the final acceptance concluded in June 2016.
