Webb4 dec. 2024 · A spallation neutron source at the Materials and Life Science Experimental Facility (MLF) in the J-PARC produces pulsed neutron beams by using 3-GeV protons with a repetition rate of 25 Hz. The neutron source emits fast neutrons on the injection of the primary proton beam, and the timing is defined as zero on $t$ . Webb17 juli 2013 · The neutron probe is relatively easy to use, accurate, and capable of measurements in real time. A probe with a fast neutron source is placed on the surface or lowered in an access tube (transparent to the neutrons), and the back-scattered slow neutrons are measured.
WebbPhysical and operational characteristics of the prototype probe, the neutron tube-transformer assembly, and the neutron tube are described. In logging operations, only the epithermal prompt fission neutrons detected between 250 microseconds to 2500 microseconds following the excitation neutron pulse are counted.
