Modelling of quadrupole cold precharger dust particle charging characteristics

A model to predict dust particle charging characteristics in a quadrupole cold precharger is developed. The space-averaged ion density and electric field are shown to increase with increasing applied voltage or discharge current. The predicted dust particle charging characteristics agree well with s...

Description
Summary:A model to predict dust particle charging characteristics in a quadrupole cold precharger is developed. The space-averaged ion density and electric field are shown to increase with increasing applied voltage or discharge current. The predicted dust particle charging characteristics agree well with simulated experiments within a factor of two for cold precharger operation after onset of corona discharges. The particle surface charge observed in the experiment increases with increasing applied voltage and agrees qualitatively well with the present model.< >
