In order to specify the beam intensity bottlenecks of the J-PARC cesiated RF-driven H ion source, the extraction and acceleration voltages (V
and V
) higher than the design values of 10 kV and 40 kV were examined. A 100 mA beam, whose about 93 mA has transverse emittances used for a common RFQ design, was stably operated with a duty factor of 5% (1 ms 
50 Hz) by using the V and V of 12.4 kV and 49.6 kV, respectively. This breakthrough with important information on the space-charge limited bottlenecks in the extraction and acceleration gaps will derive the optimal electrode shapes for the source operated with a beam intensity higher than 100 mA and realize the next generation benchmark H ion source for high intensity and high energy H LINACs.
