Description
GANIL (Grand Accélérateur National d'Ions Lourds) started the operation of the SPIRAL2 superconducting linac in 2022. Experiments in the Neutron For Science (NFS) room, specific beam dynamics studies and different technical improvements are carried out during its operation in the second half of each year, after the run of the cyclotrons in the first half of the year. Up to now, accelerated particles are mainly D+ and 4He2+ beams with energies between 7 and 20 MeV/A. First linac tunings with 18𝑂6+ and 40𝐴𝑟14+ ion beams at energies between 7 and 14.5 MeV/A were also
carried out to prepare the Super Separator Spectrometer (𝑆3) experimental area commissioning. The paper presents a summary of the beam time distribution during the second year of operation, preliminary results of specific studies on cavity failure recovery and on pressure variation in the warm linac sections induced by beam losses.
