Other than building the ion probe for that previous research, my exposure 
to that has been small.  I was sort of a temporary worker for part of a 
year for that project, and read just enough to get the job done.  
Hopefully, Brehob referrenced that Cambridge PhD thesis in her '89 or '90 
SAE paper.  If she did, and you can get a copy of that thesis, I think the 
reference list was just fabulous.  I think they often referred to 
"Langamuir probes" (spelling?) as the correct name for the sensors, but my 
memory is a little foggy here.

Another colleague has done some knock work here and looked into ion gap 
sensing.  His thesis emphasis shifted to optical methods, and I think he 
may have dropped the ion part.  That may have been because he needed 
radically new territory to cover for his thesis.  He probably still has 
some good references though, as he is very thorough in whatever he does.  
I'll ask him, too.

Later,
