Abstract：
Cusp source is one of the essential elements in high density cyclotron, whose properties have a great impact on the extracted beam of the cyclotron. The article introduces the design and machining of the H- cusp source applied to the high intensity proton beam cyclotron. By investigating deeply the technology of high intensity plasma production, long life DC filament emission of electrons, magnetic confinement, electron filtering, residual gas and electron extraction control, we designed a new cusp source with an average beam density of 15—20mA based on the 10mA H- cusp source at CIAE.
