On the interpretation of Langmuir probe data inside a spacecraft sheath

QC 20100519. Uppdaterad från submitted till published (20101213).
If a Langmuir probe is located inside the sheath of a negatively charged spacecraft, there is a risk that the probe characteristic is modified compared to that of a free probe in the ambient plasma. We have studied this probe-in-spacecraft-sheath problem in the parameter range of a small Langmuir probe (with radius r(LP)<U-1, there is first a transition region II in applied potential, U-1
