More Spacecraft Shielding Backfired in Solar Maximum
A modeled LISA-like system gained charged-particle stopping events as aluminum mass rose.
Summary
A modeled LISA-like system gained charged-particle stopping events as aluminum mass rose.
Spacecraft structure can stop incoming particles, but it can also create secondary particles. A LISA-like charging analysis found that increasing surrounding aluminum from 16 to 24 grams per square centimeter reduced the stopping-proton population by 2.3% at solar minimum while increasing it by 17.0% at solar maximum, within the reported uncertainties. A first-order projection put the corresponding net charging-rate changes near minus 2% and plus 11%. The result is a modeled design tradeoff for precision test masses, not a measured failure of a flown spacecraft.
