	After reconfiguration of the low energy (35 keV) and the medium energy (750 keV) transport lines in 2009-10, the Brookhaven linac delivered the highest intensity beam since it was built in 1970 (~120 μA average current of H⁻ to the Brookhaven Linac Isotope Producer). It also delivered lower emittance polarized H⁻ ion beam for the polarized program at RHIC. To increase the intensity further, the match into the RFQ was improved by reducing the distance from the fnal focusing solenoid to the RFQ and replacing the buncher in the 750 keV line with one with higher Q value, to allow operation at higher power. We also found that drift tube linac tank number 7 was operating with about 1 MW lower power than design. The transmission efficiencies and beam quality will be discussed in the paper.
