Preliminary report on the Pinex at TREAT. [Pinhole experiment for nonredundant pinhole array imaging of LMFBR fuel pins]

The neutron image of a GETR fuel pin was observed in a pinhole experiment (Pinex) performed at TREAT. The signal amplitude, recorded with intensified television cameras, compared well with expectations. The results carry favorable implications for continued development of nonredundant pinhole array techniques, as well as for refinement of single pinhole experiments, as diagnostic tools for the LMFBR safety program.
