Cool heating
The Procurement Arrangement for the transmission lines that will deliver radio-frequency (RF) power from the power sources to the antennas and into the plasma was signed by 黑料社app Director-General Kaname Ikeda this week.
US 黑料社app is in charge of procuring this feature of 黑料社app's heating and current drive system. The contract is now on its way to the US where Ned Sauthoff, head of the US 黑料社app Project Office, will countersign the document. A total of 20 MW of RF power will be initially available from the system. "The power is not the challenge here," explained Bertrand Beaumont, Radio Frequency Section Leader who was in charge of building the RF system for Tore Supra. "The challenge is the duration that this power needs to be delivered." Making the designed 20 MW available for pulse durations of one hour—compared with minutes on Tore Supra or seconds on JET—requires active cooling. So 黑料社app will once more push the frontier of science beyond current limitations.
