Paper Abstract

As part of the Strategic Defense Initiative (SDI) program, Brookhaven National Laboratory (BNL) has constructed a Neutral Beam Test Facility (NBTF). This facility uses surplus capacity from the 200 MeV H- linac injector for the Alternating Gradient Synchrotron (AGS). An H- beam can be transported into the experimental area via a beam transport tunnel containing magnetic optics and a beam spectrometer. A reference target system, situated at the end of a 100-meter vacuum flight path extending from the experimental area confirms the pointing direction of the particle beam. This reference target system can also provide pointing direction information for laser beams. The facility is normally operated with a particle beam energy of 200 MeV and a beam current of approximately 0.5 mA (4.5 pps, 450 μsec pulse length) transported to the experimental area. Operation at lower beam energy is possible but at reduced beam current. A low divergence laser beam may be folded into the particle beam path as part of an ATP-related experiment. The facility is now in operation, and an ATP experiment is scheduled to run during May 1989.
