Well, I did actually try both antistatic garland and a few simple
needles and they made very little difference below 3kV. I had not
heard of this carbon fiber brush but I will look into it. I find it
hard to believe that it is going to be able to reduce the corona
threshold to below 1kV (which we would need), but I will look.

Thanks,

Sean
