Hi all,

	I attended this afternoon at CERN the FDR for the ALFE PA/S. The review 
went very well, and I have already heard informally that the green light 
will be given to submit the pre-production engineering run. That is 
great new, and is another very major milestone achieved! 
Congratulations to the BNL team on this very successful outcome of many 
years of intensive work!
	It is great to see that we have now successfully completed the 
development phases of our custom ASICs, which started many years ago. 
There are surely still challenges to be faced in the preproduction and 
then production of ~80k chips for each of ALFE and COLUTA.  However, it 
was not long ago that it was quite unclear whether it would even be 
possible to develop custom rad-tol ASICs, particularly with such low 
power rails, that would be able to meet our very stringent analog 
performance requirements. Not only have we now successfully accomplished 
this, but we did for both ASICs with one less iteration that we 
originally believed would be needed!

        All the best,
                        John
