ELECTROSTATIC RETURN OF CONTAMINANTS

Description:

The ESR tool is a first generation computational code created for the purpose of computing the return characteristics of spacecraft generated contaminants, which return to the spacecraft via the electrostatic return mechanism.  The ESR code does not compute the spacecraft charging, this task is left to preexisting codes.  The ESR code does compute the Debye sheath (if necessary), the returned contaminant mass rate, returned mass flux, returned mass ratio, return velocity, and surface sputter (where applicable).  To help the user, default values have been supplied for all program inputs.  However, the user is encouraged to supply the program with appropriate inputs which accurately reflect the specific spacecraft and environmental conditions being modeled.
