Description

Abstract
The Brookhaven National Laboratory (BNL) 200 MeV Drift Tube Linac (DTL) operates at 6.67 Hz, delivering H⁻ beams for both the polarized proton program at RHIC and isotope production at BLIP. Over the past two decades, targeted upgrades—especially within the low-energy and medium-energy beam transport (LEBT and MEBT) sections—have dramatically enhanced linac performance. Beam transmission for high-current isotope production has improved by more than 100%, while transverse emittance has been halved for polarized proton operation. Moreover, beam losses have been reduced by three orders of magnitude, significantly lowering radiation levels and enabling higher current delivery. These upgrades translate into increased beam intensity to BLIP and superior quality and stability to EIC, marking a transformative step for the linac’s long-term operational reliability and scientific output.
