As a result, dedicated efforts were put into producing a more compact more robust more reliable and easier to assemble RF finger design for the new machine. The work was done in parallel on the beam coupling impedance reduction, which have a direct impact on the electron beam lifetime, and on the mechanical aspect with FEA validation and geometry optimization. Many test have been made, in a mechanical laboratory, including high resolution 3D computed tomography images in order to measure the electrical contact, and also in the existing ESRF storage ring with the electron beam, to validate the final design before launching the series production PB - JACoW Publishing CP - Geneva, Switzerland SP - 11 EP - 14 KW - vacuum KW - SRF KW - impedance KW - coupling KW - storage-ring DA - 2018/12 PY - 2018 SN - 978-3-95450-207-3 DO - 10.18429/JACoW-MEDSI2018-TUOPMA07 UR - http://jacow.org/medsi2018/papers/tuopma07.pdf ER -
