Hi Boris,

I'm thinking that a larger toriod serves two benifits: a larger 
charge reserve to feed the streamer as you mentioned and the 
background E-field. Example, raise the toriod to just under breakout 
and the E field at a point in space in the vicinity of the torid will 
increase as well.  It seems like this will stress the molicules and 
put them into a higher energy state (read this to mean that it would 
take less energy to put them over the top and cause ionization).  If 
this thinking is true, then both field and reserve capacity are important.
