Aldermaston. 2161100100011 INC-SOURCE (D-T) Low energy deuterium beam on rotating 2161100100012 tritium target. The irradiation was performed over 2161100100013 two days with a total output from the accelerator of 2161100100014 2.65 x 10**16 neutrons 2161100100015 SAMPLE U-238 foil sandwiched between two nickel foils 2161100100016 as neutron flux monitors. The complete package 2161100100017 was covered with cadmium to eliminate thermal 2161100100018 neutron capture.
