The upgrade of the brookhaven linac isotope producer (BLIP) and the bnl linac

摘要

An upgrade project was recently completed on the 200 MeV H~- linac and the Brookhaven Linac isotope Producer (BLIP) in order to improve radioisotope production capacity and relability. The average beam current has increased from 60 #mu# A to 150 #mu# a. The increased average current is the result of increases in peak current from 25 mA to 37 mA, pulse repetition rate from 5 to 7.5 Hz, and pulse width from 500 to 530 #mu# s. To achieve this performance the 35 keV, 750 keV and 200 MeV beam transport were improved, and the RF transmission lines and RF power supplies replaced. Improvements to the linac control system, and the optics and vacuum system of the 200 MeV transport were implemented. At BLIP the target cooling system was upgraded to 3t kW and automated, the targets and target mechanical systems replaced with a more robust design, and the control system upgraded. With these enhancements BLIP is ready to address the lack of availability of acceleratory produced medical and research isotopes.
