A large high current EBIS source, working at room temperature, and using a noncryogenic solenoid, has been completed in Saclay. This source, whose current density is lower ({approx_equal}100 Acm{sup {minus}2}) than the cryogenic EBIS, has been designed to be used at very low pressures with turbo and Ti sublimator pumping. An ultimate vacuum of 8{times}10{sup {minus}12} mbar has been reached and may be obtained in a few days after opening. This ultrahigh vacuum allows very long confinement times. The electron beam has been injected and large amounts of Ar{sup 16+} and Ar{sup 17+} ions have been obtained in July. These preliminary results are in good agreement with theoretical simulations. More details about the special dynamics of the warm EBIS are presented. {copyright} {ital 1996 American Institute of Physics.}
