Abstract:
Recently we demonstrated threshold Key Performance Parameter of the FRIB linac system by acceleration of Ar-36 ion beam up to 204.4 MeV/u. The staged commissioning of the linac started in 2017 with beam acceleration in the CW RFQ and continued in following years by acceleration of argon beam to 2 MeV/u in 2018, to 20 MeV/u in 2019 and KPP energy of 200 MeV/u was achieved on March 19, 2020 by using only 251 SC cavities out of 324. The beam commissioning periods were very short to allow completion of hardware installation in the tunnel. This talk will present status of accelerator systems prior to and during the commissioning, beam tuning procedures, beam measurements and main results of each commissioning stage.
