Neutron Radiography with a Sealed-Tube Neutron Generator and Graphite Moderated System
Neutron radiographs of good quality have been produced by using a sealed-tube neutron generator and a graphite moderator system. The graphite moderator is a right-cylinder 76.2 cm in diameter and 76.2 cm high. A thermal neutron flux at the object of 1.1 x 105 n/cm2-sec and a cadmium ratio of 3.5 was...

| Summary: | Neutron radiographs of good quality have been produced by using a sealed-tube neutron generator and a graphite moderator system. The graphite moderator is a right-cylinder 76.2 cm in diameter and 76.2 cm high. A thermal neutron flux at the object of 1.1 x 105 n/cm2-sec and a cadmium ratio of 3.5 was measured. The collimator ratio was 7.25; the X-ray intensity was 0.50 mr/sec; and the resolution was. measured to be 0.025 cm. Experimental techniques for determining fast and thermal neutron fluences are also described. |
