Commissioning of the ECH/CD system on JT-60SA during the integrated commissioning phase

On JT-60SA an integrated commissioning has been conducting. During the integrated commissioning phase, measurements of the transmission efficiency and the conditioning of the ECRF TLs have been carried out. In order to evaluate the transmission efficiency, the RF power was calorimetrically measured at the dummy loads (DLs) installed at two different positions close to the gyrotron and the end of each TL. As a result, the transmission efficiency was evaluated to be 70% for Unit 1, and 81-85% for three frequencies of Unit 2. The commissioning and conditioning of the ECRF systems has also been conducted. The progress of the commissioning is also reported.
