A collaboration between Oak Ridge National Laboratory and Western kentucky University examins the problem of characterization and assay of unclear waste with high intrinsic neutron and gamma-ray fields. This waste is defined as Remote handled-Transuanic waste (RH-TRU). A Radiofrequency Quadrupole Linac is used to produce pulses of neutrons, which impinge on the drum that contains the nuclear waste. The neutrons, after being thermalized in the matrix of the drum, are captured by the fissile material (~(239)Pu or ~(235)U), which releases fast neutrons upon fission. Experimental results will be presented to show the versatility of employing the RFQ with the Differential Die-away Technique.
