The JET divertor LIDAR system, KE9D, is being modified to perform measurements of plasma edge electron temperature and density in the new gas-box divertor configuration. The change involves raising the line of sight from the divertor region so that the laser beam passes through the plasma edge reaching a depth of ~5cm inside the boundary. Changes are also being made to the detection system. This currently employs a grating spectrometer and a streak camera.
