Abstract
A transmission system has been designed to produce a high intensity (s imilar to 100 W) and high quality (well-collimated and high purity) be am in the submillimeter wave range (f=354 GHz). Calculations using the Huygens equation for scalar diffraction show that this system can pro duce a high quality beam. The final goal is to apply it to scattering measurements of density fluctuations driven by instability and wave pr opagation during ion cyclotron resonance heating in the Compact Helica l System (CHS) in the National Institute for Fusion Science at Nagoya. It will provide a high S/N ratio and high spatial and wave number res olution.
