Abstract : Science Applications, Incorporated (SAI) fielded two experiments on the Mighty Epic Event: (1) a Neutron Time of Flight (NTOF) experiment that made nine measurements of neutron fluence as a function of time; and (2) a Fast Spectral experiment that made 18 X-ray fluence measurements as a function of spectral energy, plus two gamma flux measurements. Data were recorded on oscilloscopes in Roses 004, located in the ROSES drift, and in alcove 1-4 near station 2. Digital data were generated in ROSES 004; transmitted to trailer 12039, in the mesa trailer park, and stored on magnetic recording tape. Excellent data were recorded on all channels. The NTOF data was particularly noise-free which has not been the case on several previous tests. The 'clean' data can be attributed to revised system grounding techniques and the use of short signal cable runs to the ROSES.
