Re: Bertan HV

["Paul T. Debevec" <debevec@uiuc.edu>]

Dear Peter,
I never had red Bertan supplies.  I do have (but I do not know where it 
is) a supply with a gray panel that had one channel negative and one 
channel positive.  I think that this is the supply that you used when 
the ePC were here.  I doubt that you will find Illinois property tags on 
the red supplies that you are using.  If one channel is useful, I can 
hunt for the gray panel supply.  It is likely with Steve or Matthias.  
If you need more than one channel, we can see if one of our high energy 
colleagues can help out.  Both Mats Selen and Steve Errede have done 
chambers and may have something available.  I could contact Bertan to 
see if they have some in stock. My guess is no.  I am out of town 
Friday, but I will look for email later today and Thursday.
Regards, Paul
