Neutronic Spectrometry Measurements in Sodium

MEASUREMENTS WERE MADE OF NEUTRONIC PENETRATION IN SODIUM, WHICH COULD SERVE AS A REFERENCE AND AS A BENCHMARK FOR COMPUTER CODES. THE MODEL EMPLOYED CONSISTED OF AN ASSEMBLY OF 7 CONTAINERS FULL OF SODIUM FOR A TOTAL OF 10 TONS AND A USEFUL LENGTH OF ALMOST 4 METRES. MEASUREMENTS WERE PERFORMED AT VARIOUS DEPTHS ALONG THE CENTRAL AXIS OF THE STRUCTURE WITH PROTON RECOIL PROPORTIONAL COUNTERS. THE ENERGY BAND EXPLORED WAS BETWEEN 100 AND 650 KEV. HERE WE REPORT NOT ONLY THE ORIGINAL SPECTRA OF THE IMPULSES BUT ALSO THE NEUTRONIC SPECTRA FOUND BY UNFOLDING WITH THE SPEC-4 CODE
