- Summary:
- The DIII-D Fast Wave Current Drive (FWCD) system employs a pair of resonant loops of transmission line to reduce the four element phased antenna array to a two-port system. The equivalent two-port can be characterized by a 2 × 2 admittance matrix Y{sub ij}, the off-diagonal elements of which are non-zero due to the reactive coupling between the elements on the antenna array. By connecting another two-port network (a ``decoupler``) in parallel with the two feedlines, it is possible to reduce the off-diagonal elements of the admittance matrix describing the resulting two-port device to zero, thereby effectively producing a system with no coupling between the feedlines. In this paper we report a comparison of the theoretically predicted and experimentally determined characteristics of a decoupler in a high power ICRF system.
