Hi Dave,

    I very much like your approach and especially your statement in the conclusions -  the solenoid and flux return (HCAL) are a great foundation.  The traditional argument against the "ePHENIX" approach has been to focus on a particular aspect of detector performance and use that to declare the approach unsatisfactory, and this undercuts that argument very effectively.  I'm sure what you will say on slide 10 (something like "...this is one possible implementation..." ) will be consistent with your approach.

Dear sPHENIX,

I'll be giving a 10 minute (!) talk this Thursday at the EICUG Detector
Discussion Meeting at Temple University.  I'll be the last in a series
of talks about detector concepts, and the talk is so brief, that I'm
planning to focus on one main point – that starting with the BaBar
solenoid in the sPHENIX support structure and with the oHCal as an
instrumented flux return is a a great starting point for an EIC
detector.  Of course, you can do even better by also using the TPC and
the MVTX and the EMCal, but I think presenting a nearly "blank canvas"
as part of the spectrum of options has the potential to be maximally
inviting.

My draft slides are here:

Nils and Jin helped me get some up to date dimensions for the current
EIC concept detector to Dan Cacace, who has made some nice 3D
renderings.  I'm very happy to get feedback.  The big constraint is the
alloted time, so for anything significant that goes in, something will
have to come out.

I need to add names and institutions to some of the slides and finish
adding labels to some of the renderings.

Cheers,
Dave
