Construction Status and Test Operation of the DIAC at KAERI

KEK (High Energy Accelerator Research Organization) TRIAC (Tokai Radioactive Ion Accelerator Complex) was a radioactive isotope accelerator that can provide beams of uranium fission fragments with a maximum energy of 1.1 MeV/nucleon produced by protons of 30 MeV and 1 µA (30 W in beam power, actually deposited in the production target) from the JAEA Tandem Accelerator. The DIAC team has a plan to reassemble this device as a stable ion beam accelerator with a minimized change for the low energy beam line including the ion source and the target system. The new stable ion accelerator will be used not only for basic research but also for the application of heavy ion beams. Until recently, most of power supply, the cooling water supply and vacuum pump systems have been installed for a performance evaluation of the DIAC. The experimental results of the plasma generation in the ECR ion source are presented. We are planning to evaluate a radiation shielding analysis for an operation permit and perform the beam transport experiments from the ECR ion source to the IH linac by the end of next year
