  The for­mer SANAEM RFQ is up­graded with a newly man­u­fac­tured cav­ity, made of oxy­gen-free cop­per (OFC), hav­ing the ca­pa­bil­ity of ac­cel­er­at­ing pro­tons from 20 keV to 1.3 MeV. In the as­sem­bling of cav­ity vanes, flanges, etc., in­dium wire is pre­ferred over the braz­ing process pro­vid­ing a more flex­i­ble and easy method for vac­uum seal­ing. After as­sem­bling the cav­ity, argon plasma clean­ing is per­formed for the final clean­ing and RF pre-con­di­tion­ing. Vac­uum tests re­vealed that lev­els of 2·10-7 mbar could be achieved quite eas­ily. RF power con­di­tion­ing of the RFQ cav­ity is suc­cess­fully com­pleted with the ob­ser­va­tion of quite few sparks. In the com­mis­sion­ing tests with the pro­ton beam, a mag­netic an­a­lyzer is used to mea­sure the en­ergy of the par­ti­cles. This paper pre­sents the strat­egy and the re­sults con­cern­ing the com­mis­sion­ing of the pro­ton beam with spe­cial em­pha­sis on the RFQ cav­ity.
