Paper Abstract

A single free standing synthetic diamond window seems to have higher absorption coefficient value atmillimeter wavelength region at this time although it is claimed that it possesses good mechanical strengthand higher thermal conductivity characteristics. It certainly does not rule out the use of diamond film onsingle crystal high resistivity silicon to improve its mechanical strength and thermal conductivity. Onemay have to use an appropriate film thickness for a particular wavelength in gyrotron window application.It is also necessary to use an appropriate thickness for the silicon perhaps equivalent to a quaterwavelengthin order to avoid the reflection mismatch
