Abstract :
There is a plan to upgrade the energy of the KEK 2.5-GeV linac to 8.5 GeV relevant to the B-factory project. The increase from the present 2.5 GeV requires reinforcing the existing microwave source. In order to realize this reinforcement with a limited budget, the upgraded modulator was designed so as to utilize those components of the old modulator as much as possible, expect for a necessary change in the main line components. This article describes the upgraded modulator specifications and its performance tests
