Abstract
A method of determining payload potential may include the steps of receiving data on a first bias voltage and a resulting first collected current of a first needle of a multi-needle Langmuir probe, receiving data on a second bias voltage and a resulting second collected current of a second needle of the multi-needle Langmuir probe, assigning a value for the electron temperature in which the multi-needle Langmuir probe was operating, and using the current and voltage data, the assigned electron temperature value and Langmuir probe theory to calculate the platform potential of the multi-needle Langmuir probe.

- using the current and voltage data, the assigned electron temperature value and Langmuir probe theory to calculate the platform potential of the multi-needle Langmuir probe.
A device for determining platform potential, the device comprising:
- a multi-needle Langmuir Probe;
- and
- a processor,
- wherein the processor is arranged to receive data on a first bias voltage and a resulting first collected current of a first needle of the multi-needle Langmuir probe;
- receive data on a second bias voltage and a resulting second collected current of a second needle of the multi-needle Langmuir probe;
- assign a value for the electron temperature in which the multi-needle Langmuir probe is operating;
