“…Nevertheless, our simulations are in qualitative agreement with the field data in that they predicted statistically significant signals for every declaration in the field test where the hydrogen concentration was in fact due to a buried mine. 1.0 x 10 -8 287 745 2.6 1.0 x 10 - 8 1.0 x 10 -7 6118 14274 2.3 1.0 x 10 -7…”

“…where: A = net free-field sensor activity at EOI (dps) from eq (1) A = decay constant of the reaction product (s' 1 ) C = decay correction factor given in test report. For an uninterrupted irradiation of length T at a constant fluence rate, C is equal to [(1-exp(-AT))/AT].…”

“…In general, this calibration will be most effective if a calculated fission-spectrum-averaged cross section is used in eqs. (1 ) through (5). In particular, it should be obtained with the same fission spectrum shape and energy dependent reaction cross section as are used to establish a spectrum-averaged cross section for subsequent neutron field measurements (e.g.…”

Standard neutron fields have been developed at NIST beginning as early as 1975. They have been applied since that time as irradiation facilities and benchmarks for (1) validation of microscopic neutron interaction data for the design and operation of nuclear reactors of all types; (2) characterization of in situ neutron fields for reactor materials dosimetry; and (3) neutron transport calculations. This series of NIST Interagencey Reports (NISTIR) provides a detailed description of three of these neutron fields: the Cavity Fission Source (CFS), The Califomium-252 Fission Neutron Irradiation Facility (CNEF), and the Materials Dosimetry Reference Facility (MDRF). This report provides operational information for the CFS including facility configuration, assembly and irradiation procedures, and neutron fluence determination. NOTE: o This document describes facility operations and irradiation procedures as of 1995. o Dimensions and related specifications of facility hardware and reactor components are in the engineering units employed in the primary documentation upon which this report is based.
