Isotope production rates in a thick lead target in the reaction d+Pb at 2,52 GeV

The "Energy Plus Transmutation"-setup consists of a thick cylindrical lead target of 456 mm length and diameter of 84 mm, which is surrounded by a thick layer containing 206,4 kg of natural uranium. This small-sized target-blanket-assembly resembles the geometry and the constituents of an industry-sized subcritical system for power production and nuclear waste transmutation. The irradiations of the target-blanket-assembly are performed using deuteron beams of variable energies, delivered by the Nuclotron accelerator at the Joint Institute for Nuclear Research in Dubna. Using precision gamma-spectroscopy, the amounts of isotopes of bismuth, lead and thallium, produced in the lead target during the irradiation with a deuteron beam of 2,52 GeV [1,2] have been determined. The collected data on the isotope production are compared with the predictions of nuclear-reaction- and particle-transport-codes.
