Description
A lower hybrid current drive (LHCD) system is being installed on the Alcator C-Mod tokamak. Initially, 12 klystrons operating at 4.6 GHz will deliver a total power of 3 MW to the coupler. The LHCD system will make it possible to modify the current density profile in the outer half of the plasma. This implies that the q-profile can be manipulated, thereby enabling the study of advanced tokamak regimes. In this paper we describe the overall structure of the control and data acquisition system for LHCD. The acquisition setup collects data from the active controller, the transmitter protection and the coupler protection systems. Long pulse tests of the klystrons are presented and a monitor camera is introduced
