Charge Neutralization as Studied Experimentally and Theoretically

  • Chapter
Artificial Particle Beams in Space Plasma Studies

Part of the book series: NATO Advanced Study Institutes Series ((NSSB,volume 79))

Abstract

The problem of vehicle.neutralization is simply stated. The electrostatic potential, Φ, of an isolated sphere of radius a meters emitting negative charge at a rate of I amperes will charge up at the rate of

$$ \frac{{d\Phi }} {{dt}} = 9\frac{I}{a}{\raise0.7ex\hbox{${kV}$} \!\mathord{\left/{\vphantom {{kV} {\mu s}}}\right.\kern-\nulldelimiterspace}\!\lower0.7ex\hbox{${\mu s}$}} $$
((1))

If there is no return current, a meter-size body emitting as little as a 10 mA electron beam would be charged up to 9 kV potentials in 0.1 ms. Such large potentials would inhibit the electron beam from leaving the vicinity of the vehicle. A one ampere beam would charge up a vehicle in microseconds.
