As a part of R&D to­ward the RFQ based heavy ion ir­ra­di­a­tion sys­tem, the 1 MeV/n RFQ was de­signed, brazed, in­stalled and com­mis­sioned by staff re­searchers and en­gi­neers at KOMAC of KAERI. This 1 MeV/n RFQ sys­tem in­cludes the mi­crowave ion source, EBIS, RFQ, quadru­pole mag­nets, switch­ing mag­net and the tar­get sys­tems. The dig­i­tal based Low-Level RF was de­vel­oped to pro­vide the sta­ble ac­cel­er­at­ing field to the RFQ. This Low-Level RF has fea­tures such as di­rect RF de­tec­tion/gen­er­a­tion with­out mixer, non-IQ sam­pling, PI feed­back con­trol, it­er­a­tive learn­ing based feed-for­ward con­trol, and the dig­i­tal RF in­ter­lock. In this paper, the char­ac­ter­is­tics of Low-Level RF are de­scribed, as well as the processes and re­sults of an ini­tial RF dri­ving test for the RFQ’s RF con­di­tion­ing.
