At the Japan Proton Accelerator Research Complex (J-PARC), the operation of a 400-MeV linear accelerator (LINAC) with an extraction H ion beam intensity of 60 mA is under investigation. This intensity is 20% higher than the 50 mA achieved by the J-PARC LINAC and about 50% higher than those of operating similar LINACs in the world. Recently, the J-PARC cesiated RF-driven H ion source successfully produces a beam enabling the 60 mA operation. A 66-mA beam with 95%-beam transverse normalized rms emittance of 0.23 
mm
mrad is produced by controlling the impurities of argon, nitrogen and water molecules in the hydrogen plasma and tuning rod-filter-field.
