RE: Kicker vacuum

["David W Hertzog" <hertzog@uiuc.edu>]

Konrad,
	Yes, please go ahead with the mods for the kicker vacuum and
thanks.

	Also, from MuLan, Dan Chitwood here knows the most about them.
He has run a lot of tests in our laboratory of "cross talk" and
influence of one hit on another hit's timing.  He is also someone you
should describe your problem with (and, others like Tim Gorringe at
Kentucky, who did a lot of simulations of the thing).  If you give us
the basic "category" of the problems you are plagued with, we can point
to our expert in that (hopefully it's not yet another problem ... we
have found many as I told you in the past).

	Too bad about that thing. It had a lot of nice features but now
it is grinding down several collaborations and lots of manpower.

	Regards,
	Dave

Dear Konrad,

Thanks for your effort, Dave will comment on the kicker. In Mucap Fred 
Gray is the top expert on CAEN. He will be around most of our run,
ideal to have a thorough discussion with our FAST CERN colleagues.

Best regards

Peter
