One array in each camera will operate as a bolometer and the second as a Lyman-alpha (L-alpha) emission monitor for estimating the recycled neutral flux. The camera configuration was optimized by simulations of tomographic reconstructions of the expected L-alpha emission. The diagnostic will provide spatial and temporal resolution (10 mus) of the radiated power and the L-alpha emission that is considerably higher than previously achieved. This optimism is justified by extensive experience with prototype systems, which include first measurements of L-alpha light from the divertor.
