Usable Dimensions

Sample irradiation space in the thermal column is created by pulling out graphite stringers. Removing a graphite stringer leaves a space 4 inches square and 4 feet long. (The neutron flux gradient over the 4-foot length shows about 2% reduction per centimeter of horizontal movement away from the innermost position.)
