The ITER fusion research facility will employ twenty-four, MW-class gyrotrons for electron cyclotron heating of the fusion plasma. Each of these gyrotron will require an RF load for commissioning and periodic maintenance and testing. These loads must dissipate approximately 1 MW of long pulse / continuous RF power with less than 0.5% of the power reflected back into the transmission line. This program is using additive manufacturing to reduce the cost and improve the performance.
