Re: Power Supply Record?

[Geoff Savage <savage@fnal.gov>]

The DZero Experiment at Fermilab has a HV record that includes a  
state machine.  Fritz Bartlett, the developer of our HV record, has  
just become a "Guest Scientist Retiree" so he is still available for  
consultation.  We have a tutorial on our HV system at -
http://www-d0online.fnal.gov/www/groups/ctl/tutorials/high-voltage- 
tutorial.pdf.

I can make the software available for those who are interested.
