Abstract:
We calculate the effect of dust on drifting electrons for an LAPD sized volume.
We also calculate the settling time of dust for various grain sizes.
We conclude that very fine dust below 30 microns or so can be a problem. Larger grains fall down quickly enough even in the presence of the expected convection velocities.
We would welcome an independent verification of the calculations.
