Fast neutron spectroscope for measurements in a high intensity time dependent neutron environment

Claim 1

A SPECTROSCOPE FOR MEASURING NEUTRON ENERGY SPECTRA AS A FUNCTION OF TIME WITHIN A WIDE INTENSITY RANGE COMPRISING A PLURALITY OF ELEMENTS TO BE SIMULTANEOUSLY EXPOSED TO THE ENVIRONMENT TO BE EXPLORED, EACH OF SAID ELEMENTS HAVING A BODY OF HYDROGENS MATERIAL WITH WHICH THE INCIDENT NEUTRONS REACT TO RELEASE PROTONS HAVING ENERGIES BEARING A RELATIONSHIP TO THE ENERGY OF THE INCIDENT NEUTRONS, AN ABSORBING MEANS FOR EACH ELEMENT IN CLOSE PROXIMITY TO THE HYDROGENS MATERIAL EACH ABSORBING MEANS HAVING DIFFERENT ABSORPTION CHARACTERISTICS TO SAID PROTONS AND ACTING TO ABSORB A DIFFERENT PORTION OF THE PROTONS REACHING IT AND PASSING THE REMAINING PROTONS, AND SEPARATE MEANS FOR EACH ELEMENT TO MEASURE THE PROTON FLUX PASSING THE ABSORBING MEANS FOR EACH ELEMENT WHEREBY THE DATA THUS OBTAINED FROM THE DETECTORS CAN BE INTREPRETED MATHEMATICALLY IN TERMS OF THE ENERGY SPECTRUM OF THE INCIDENT NEUTRON ENVIRONMENT AS A FUNCTION OF TIME FOR THE NEUTRON INTENSITY RANGE FROM 1026 TO 1016 NEUTRONS CM.-2 SEC.-1.
