Abstract : In November of 1952, representatives of du Pont's Atomic Energy Division had preliminary conversations with various Argonne people concerning a movable neutron chamber for the Savannah River developmental reactor. The usefulness of such a flux measuring instrument had been demonstrated during ZPR-II experiments at Argonne. The ZPR-II facility made provisions for probing along both horizontal and vertical axes. Separate but functionally similar probes were used for each axis: an ion chamber at one end of a length of rigid aluminum tubing was connected to its galvanometer tube and amplifier at the other end by a coaxial cable passing through the bore. This entire assembly was inserted to the desired depth in air-filled sleeves passing through the fuel lattice. Six fixed sleeves were provided in the horizontal direction, while two vertical sleeves were capable of installation in any of a multiplicity of locations.
