Lightning arrestor connector lead magnesium niobate qualification pellet test procedures. [PDF]
Enhanced knowledge preservation for DOE DP technical component activities has recently received much attention. As part of this recent knowledge preservation effort, improved documentation of the sample preparation and electrical testing procedures for lead magnesium niobate--lead titanate (PMN/PT) qualification pellets was completed. The qualification

Failure analysis of rutile sleeves in MC3080 lightning arrestor connectors. [PDF]
The purpose of this SAND Report is to document efforts in the extraction and failure analyses of sleeve-style Lightning Arrestor Connectors (LACs). Several MC3080 and MC3079 LACs were recovered from the field and tested as part of the Enhanced Surveillance Campaign. A portion of these LACs failed retesting.

Lightning Arrestor Connectors Production Readiness [PDF]
The Lightning Arrestor Connector (LAC), part “M”, presented opportunities to improve the processes used to fabricate LACs. The A## LACs were the first production LACs produced at the KCP, after the product was transferred from Pinnellas. The new LAC relied on the lessons learned from the A## LACs; however, additional improvements were needed to meet ...

Investigations of techniques for reducing breakdown voltage in lightning arrestor connectors [PDF]
The success of the MC2796 and MC2797 lightning arrestor connectors (LACs) in providing lightning protection for several weapon systems has resulted in requests for other LACs with other protection capabilities. Among these has been the request for lower breakdown voltage.

Solderability study of 63Sn-37Pb on zinc-plated and cadmium-plated stainless steel for the MC4636 lightning arrestor connector. [PDF]
Cadmium plating on metal surfaces is commonly used for corrosion protection and to achieve good solderability on the 304L stainless steel shell of the MC4636 lightning arrestor connector (LAC) for the W76-1 system. This study examined the use of zinc as a potential substitute for the cadmium protective surface finish. Tests were performed with an R and

Reconstruction of the spatial dependency of dielectric and geometrical properties of adhesively bonded structures [PDF]
An inverse problem motivated by the nondestructive testing of adhesively bonded structures used in the aircraft industry is studied. Using transmission line theory, a model is developed which, when supplied with electrical and geometrical parameters ...
