ASTM E720-23 pdf free download – Standard Guide For Selection And Use Of Neutron Sensors For Determining Neutron Spectra Employed In Radiation-Hardness Testing Of Electronics.
This guide provides information on selecting and using neutron-activation detector materials for neutron spectra adjustment techniques in radiation-hardness testing of electronic semiconductor devices. It describes sensors utilized in various radiation hardness-testing facilities, with table footnotes offering insights into the suitability of each reaction based on cross-section accuracy, ease of use, and past successful applications. Additionally, the guide addresses the need for fluence uniformity, neutron self-shielding, and fluence depression corrections when determining sensor thickness, covers, and locations. These factors are crucial for accurately assessing neutron spectra from assemblies such as TRIGA and Godiva-type reactors, as well as Californium irradiators. The guide may also apply to other broad energy distribution sources up to 20 MeV.
