title: Radiological concerns in operation of intense low-energy deuteron beams.
abstract: A 40-keV, 5-mA DC deuteron beam was operated at the SARAF with the purpose of characterizing the ion source and the low-energy beam transport system. We used this opportunity to address radiological concern of operating an intense deuteron beam. Fast and thermal neutrons produced via the D(d,n) reaction were measured in the vicinity of the components intercepting the beam using various methods. We found that the neutron yield from implantation of a deuteron beam in a graphite matrix is of the order of 2 x 10(6) n s(-1) mA(-1) into 4pi.
