A 3.0mev Komac/KTF RFQ Linac

The Radio-Frequency Quadrupole (RFQ) linac that will accelerate a 20mA proton beam from 50keV to 3MeV has been designed and is being fabricated as the first phase, KOMAC Test Facility (KTF), of the Korea Multipurpose Accelerator Complex (KOMAC) project at the Korea Atomic Energy Research Institute (KAERI). The physical, engineering designs and fabrication status of the RFQ are described.
