	Funding: NASA In March 2014, we have successfully commissioned a newly designed low charge high brightness laser ion source (LIS) which delivers various singly charged heavy ions to the electron beam ion source (EBIS) at Brookhaven National Laboratory. Now the LIS is used at routine operation of the RHIC-AGS accelerator complex and is providing stable less-contaminated beams. The laser power density was optimized to provide singly charged ions with low material consumption rate. The nominal laser energy on the target is around 500 mJ with 1064 nm Nd:YAG of the wave length. The induced plasma by the laser is transported through a 3 m pipe to stretch ion beam pulse length to match the EBIS’s requirement and the degradation of the beam current caused by the long drift section of the pipe can be compensated by a longitudinal magnetic filed induced by a coil surrounding the pipe. We also employed a twin laser system to extend the beam width further. At the conference, we will discuss the effect of the new LIS on the various accelerated beams through the EBIS, RFQ and IH-linac.

	Brookhaven 200 MeV H⁻ linac has been operating for last 44 years and providing beam to nuclear physics program and isotope program. Two upgrade programs are in progress to make machine more reliable and to double the intensity. This paper will discuss in detail these upgrade programs.

Brookhaven 200 MeV H⁻ linac has been operating for last 44 years and providing beam to nuclear physics program and isotope program. Two upgrade programs are in progress to make machine more reliable and to double the intensity. This paper will discuss in detail these upgrade programs.
