title: A compact electron cyclotron resonance proton source for the Paul Scherrer Institute's proton accelerator facility.
abstract: A compact electron cyclotron resonance proton source has been developed and installed recently at the Paul Scherrer Institute's high intensity proton accelerator. Operation at the ion source test stand and the accelerator demonstrates a high reliability and stability of the new source. When operated at a 10-12  mA net proton current the lifetime of the source exceeds 2000 h. The essential development steps towards the observed performance are described.
