Thermal neutron distribution 
It include six AmBe neutron source (strength （3.7～6.3）×106s^{1},Reference date 1967.7) and moderating medium constituting with olefin and graphite. The sources were distributed proportionally in the olefin with average neutron temperature between 293 K and 300 K, inside or outside of the graphite pile. The distance between source and center of moderator is 200mm. The thermal neutron fluence field is in the center of moderator, The uniform volume is a sphere with diameter 20 mm.
