Deuteron Beam Power Ramp-Up at SPIRAL2

Résumé

The SPIRAL2 linac commissioning started on 8 July 2019 after obtaining the authorisation to operate by the French Safety Authority. The tuning of the two Low Energy Beam Transport (LEBT), Radio Frequency Quadrupole (RFQ), Medium Energy Beam Transport (MEBT), Superconducting (SC) linac and High Energy Beam Transport (HEBT) was done with H⁺, 4He2+ and D⁺ beams during three periods of six months each in 2019, 2020 and 2021. The results obtained in 2021 with a D⁺ beam are presented. The strategy for the tuning of the MEBT, including three rebunchers, is described. The comparison between the beam parameter measurements and reference simulations are also presented. The main results of the power ramp-up to 10 kW in the linac with a 5 mA D⁺ beam are next reported. Finally, the extrapolation from the nominal power (200 kW) to the obtained results is analysed.
