This paper is a progress report on the studies of the BNL volume H{sup {minus}} ion source. We have measured the H{sup {minus}} yield, {ital I}{sub H{sup {minus}}}, and the ratio {ital I}{sub {ital e}}/{ital I}{sub H{sup {minus}}} as function of the size of the extraction aperture, strength of the conical filter field, size and position of the filament, and of the phase of the filament heating current. The H{sup {minus}} current density in the extraction aperture was lower for the largest aperture, while there was a broad maximum when the conical field varied. Position of the filament and the phase of the filament heating current are very important parameters.
