motivations for building new flash ADCs

[Frederick Gray <fegray@berkeley.edu>]

Hi, Peter,

Rene signed me up to give an instrumentation seminar in Louvain next Wednesday
on our new FADC board.  I should probably begin by explaining why we 
started builing this wonderful new device.  There were some clear reasons
that I can explain: pulse shape discrimination in the DEMON detectors, 
monitoring of thresholds on all TPC anodes/cathodes.  However, one of our 
largest motivations was the Alvarez search.  I am not sure that we have
ever written down (or even clearly thought out) exactly how we intend to 
use the additional data from the FADC to improve on a hypothetical 
TDC400-based analysis.  Any suggestions on how to formulate this best?

Also, I will continue Brendan's analysis of the source calibration data
and come up with some preliminary quotable numbers on the observed n/gamma
separation efficiency at various energies.  I will try to have them
ready tomorrow, since we will clearly need to discuss them before my 
presentation. 

Thanks,

-- Fred
