Health Physics Lab
Picatinny Arsenal, NJ
Description: This facility contains two dry cell self shielded irradiators for assessing the effects of high intensity radiation on items of interest. One of the irradiators, known as the Dougherty Box, is a heavily shielded chamber that contains a cobalt-60 source, which emits gamma photons at 1.17 and 1.33 Mev. The other irradiator contains Cs-137, which emits gamma photons at 0.667 Mev. These devices are licensed by the U.S. Nuclear Regulatory Commission (NRC) for R&D; purposes.
Reliability Physics/Failure Analysis Laboratory
Picatinny Arsenal, NJ
The Reliability Physics / Failure Analysis Laboratory provides excellent capabilities. The Scanning Electron Microscope (SEM), equipped with both wavelength and energy dispersive spectrometers, enables the observation of microstructures and performs full elemental (both qualitative and quantitative) analysis. The SEM can produce images with resolutions as fine as 4nm. The laboratory contains all the equipment required to sample preparation and surface analysis, including high quality optical microscopes, carbon and gold coaters and a dedicated machine shop. Coupled with other fine facilities in the A&IFD; Laboratories, this lab can perform a number of analytical techniques in the area of semi-conductor failure analysis, such as voltage contrast and current induced failure detection. In the voltage contrast mode, a suspect device can be lowered while being examined with the microscope. All positively charged metalization runs will appear dark while negatively charged runs will appear light. While functioning, isolation of defective areas can easily be accomplished.
