TI - Three Years of Operation of the SPIRAL2 LINAC: Cryogenics and Superconducting RF Feedback J2 - Proc. of LINAC2022, Liverpool, UK, 28 August-02 September 2022 CY - Liverpool, UK T2 - International Linear Accelerator Conference T3 - 31 LA - english AB - The superconducting LINAC of SPIRAL2 at the GANIL facility is in operation since October 2019. Its 26 super-conducting quarter wave resonating cavities (88 MHz) are operated at a nominal gradient of 6.5 MV/m, but most of the cavities can be operated up to 8 MV/m. They are integrated into 19 cryomodules and cooled down at 4 K by a dedicated refrigeration cryogenic system. In this paper, we will present a feedback after five years of operation of the cryogenic system, focusing on the main problems that have been faced, and on the diverse evolutions performed in order to improve the cryogenic system and to increase its reliability. We will also provide a feedback of the superconducting cavities performances status after three years of operation PB - JACoW Publishing CP - Geneva, Switzerland SP - 479 EP - 482 KW - cavity KW - cryogenics KW - cryomodule KW - operation KW - linac DA - 2022/09 PY - 2022 SN - 2226-0366 SN - 978-3-95450-215-8 DO - doi:10.18429/JACoW-LINAC2022-TUPOGE02 UR - https://jacow.org/linac2022/papers/tupoge02.pdf ER -
