Abstract
We use ion acoustic waves and an electron‐emitting hot probe to measure Langmuir sheath thickness as a function of negative electrode voltage. We find the thickness varies as voltage to the ¾ power, as expected, which suggests diagnostics for plasmas based upon these methods.This publication has 5 references indexed in Scilit:
