Abstract :
As part of a joint accelerator research project with the Los Alamos National Laboratory, NBS is now building a 200 MeV, high current, CW racetrack microtron (RTM). Upon its completion, scheduled for 1984, we propose to use this machine to provide CW electron beams to nuclear physics experimenters, and also as the injector for a second stage RTM to boost the final energy to one GeV. A building addition of 35,000 square feet will house the second stage RTM and new experimental facilities. Subharmonic RF beam splitting is planned to allow up to three simultaneous beams for experiments, with currents up to l00¿A each. In addition, low and high energy beams at low currents for tagged-bremsstrahlung experiments can be delivered at the same time. This proposed multi-user facility is intended to be a national center for electromagnetic nuclear physics research.
