Failure analysis of rutile sleeves in MC3080 lightning arrestor connectors. [PDF]
, 2006 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 connector lead magnesium niobate qualification pellet test procedures. [PDF]
, 2009 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

Investigations of techniques for reducing breakdown voltage in lightning arrestor connectors [PDF]
, 1977 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.

Lightning Arrestor Connectors Production Readiness [PDF]
, 2008 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 ...

Solderability study of 63Sn-37Pb on zinc-plated and cadmium-plated stainless steel for the MC4636 lightning arrestor connector. [PDF]
, 2004 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

Upward Lightning at the Gaisberg Tower: Initiation Mechanism and Flash Type and the Atmospheric Influence [PDF]
, 2022 Upward lightning is much rarer than downward lightning and requires tall ($100+$~m) structures to initiate. It may be either triggered by other lightning discharges or completely self-initiated. While conventional lightning location systems reliably detect downward lightning, they miss a specific flash type of upward lightning that consists only of a ...

Exploring terrestrial lightning parameterisations for exoplanets and brown dwarfs [PDF]
Planetary & Space Science, 204 (2021), 105247, 2021 Observations and models suggest that the conditions to develop lightning may be present in cloud-forming extrasolar planetary and brown dwarf atmospheres. Whether lightning on these objects is similar to or very different from what is known from the Solar System awaits answering as lightning from extrasolar objects has not been detected yet. We explore

Theory of ball lightning [PDF]
Sci. Rep. 6, 28263 (2016), 2014 We present a comprehensive theory on the formation of ball lightning, a luminous sphere sometimes observed after normal lightning. In a ball lightning event, a relativistic electron bunch can be produced by the stepped leader of lightning and coherently emit high-power microwave when striking the ground.

Seasonal Predictability of Lightning over the Global Hotspot Regions [PDF]
, 2021 Skillful seasonal prediction of lightning is crucial over several global hotspot regions, as it causes severe damages to infrastructures and losses of human life. While major emphasis has been given for predicting rainfall, prediction of lightning in one season advance remained uncommon, owing to the nature of the problem, which is short-lived local ...
