AXUV bolometer and Lyman-alpha camera systems on the TCV tokamak

A set of seven twin slit cameras, each containing two 20-element linear absolute extreme ultraviolet photodiode arrays, has been installed on the Tokamak a Configuration Variable. 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. (C) 2004 American Institute of Physics.
