sPHENIX discussion of software

[Martin Purschke <purschke AT bnl.gov>]

Hi Spencer and Dennis,

nice presentation, right on point. I like the slide titles, they are
refreshing and cool. And thank you for posting early!

I have a few suggestions for - hopefully - even more "punch" of the
message.

First, slide 3's optics - there is a nicer artist's view of sPHENIX out
there, and we have cool pictures of both an actually existing  Emcal
module, and our collection of HCAL modules, which might make this a but
more tangible. I just gave a presentation where I showed how sPHENIX
takes shape and extracted two slides from it at
http://www.phenix.bnl.gov/~purschke/forSpencer.pptx for your
consideration (sl 2, really). The HCal modules have me in the picture
(because it was my talk); we can certainly get you a new one without
anybody in it.

I know you feel strongly about your work that you show with slide 5, but
for this particular topic it is kinda hanging there and you might
consider sacrificing it for a more elaborate lead-in for the real
message. (That LED testing would have been good as a dedicated abstract
in its own right).

The bullet points in slide 6 are not wrong, but unless one is already an
expert, I don't think the message sinks quite in. 16 samples @ 6x beam
clock gives you this much, we can take only that much, so something has
to give - I think that makes it clearer than the 120MHz and the limit
where we lose that sort come out of nowhere. Some of that numerology and
pointers to much more detail is on Sl 14 of my last coll. meeting talk,
see below.

The blue histograms in slides 7 and 9 are hard to understand without
some lead-in. I would show an actual 16-sample waveform response to a
particle in the Emcal - for a few ready-made ones, look at the same coll
meeting talk https://indico.bnl.gov/event/8837/ sl 16 & 17. You can use
that to explain what one sees in the top plot in sl 7 and where those
numbers come from.

That's why I mentioned slide 5 - you may need to sacrifice something to
have enough time.

Just suggestions - please see what you want to incorporate.

Best, and have fun with the presentation.

        Martin
