Abstract

In GaAs, InGaAs, InGaP-photocathodes for I² to bond HES with input glass windows vacuum thermodiffusion welding (TDW) is used. By existing technology of TDW some problems are appeared, that connected with fragility, deformation, thermic matching of materials, also with thermic stresses in welded materials. In this report describe the methods of concrete problem-solving that attend TDW is described.
