$H^{-}$ Source Development at CERN

Future CERN programmes for LHC and ISOLDE require increasing the beam intensity and brightness from the PS Booster (PSB). This could be achieved by injection from a higher energy H- linac. A new injector will require a high performance, high reliability, negative hydrogen ion source. This paper will present the requirements for such a source together with the first results for a prototype microwave driven source.
