I wrote this one at DDD, and it’s worth re-printing. I will slowly reprint my best of the best of prior works at DDD.
Gasket source, not that expensive https://mosequipment.com/products/titanrf-faraday-foam-gasket?variant=32016121921638 Shielding effectiveness calculator https://cecas.clemson.edu/cvel/emc/calculators/SE_Calculator/index.html CME discussion page at Montana State. I spent over 1 hour looking for Earth Ground Level frequency levels of electromagnetic impacts created by the CME. CME is typically described as a Billion or more tons of “charged particles”. the results where thin to none. http://solar.physics.montana.edu/press/faq.html Interesting discussion on non-nuclear EMP weapons and engagement. https://apps.dtic.mil/sti/pdfs/AD1124730.pdf A source thats need further research by me. https://www.researchgate.net/publication/345096381_The_Impact_of_Coronal_Mass_Ejections_on_the_Seasonal_Variation_of_the_Ionospheric_Critical_Frequency_f0F2 July 23, 2012, a massive CME https://www.nasa.gov/goddard/mapping-the-journey-of-a-giant-coronal-mass-ejection Another resource https://hesperia.gsfc.nasa.gov/summerschool/lectures/vourlidas/AV_intro2CMEs/additional%20material/corona_history.pdf Another b by bz really good, but it wil it be good enough to shut down grids prior to the next big one?
