	Bulk of the beam from the linac is used for Brookhaven linac isotope producer (BLIP). The average current from the linac is up 125 uA. At this current BLIP has several target failures and yield uncertainty due to partially melted target salt. To reduce current density, we have tried octupoles in the past but did not produce uniform beam as calculated due to the x-y coupling present in the linac. A beam painting scheme with help of one x and y steers with 90 phase leg at 5 kHz will provide desire current density at the target. This paper discuss beam optics of the blip transport line and beam footprint on the target with given constrains.
