The results of the investigation of the effect of cesium seeding on the properties of hydrogen and deuterium multicusp ion source plasma will be reported. The plasma properties were studied using electrostatic probes (electron density and temperature, plasma potential) and photodetachment (negative ion/electron relative density). In a multicusp hybrid ion source we found that the negative ion/electron density ratio is enhanced by cesium seeding, particularly at low pressure (a factor of 4 at 1 mTorr), while both the electron temperature and the electron density are reduced. We have also investigated the hydrogen-cesium volume source developed at the RRC Kurchatov Institute. {copyright} {ital 1996 American Institute of Physics.}
