sPHENIX is a new detector at RHIC.

Hi Dennis,

nice slides.

The A/B scenarios that you explain on slides 12/13 in detail are shown 
before (Sl 7). Scenario A lists the Au+Au part as commissioning, while B 
lists this as physics running. You explain this on Sl 13 that part of 
p+p is then used for commissioning (which we will need to some extent no 
matter that, even in scenario A - in PHENIX we learned the hard way that 
p+p has much more stringent requirements than HI).

The committee might be confused about this without the later 
explanation. You might want to consider adding the one sentence to that 
effect on sl 13 earlier.

Just as background for Sl 14, with the scenario that has the Au+Au in 
the middle:

Each species switch will require us to physically change the oscillators 
in each ADC clockmaster module. We are now set for Au+Au. Starting with 
pp, we would need to change that, then change back for Au+Au. The 
in-the-middle scenario adds yet one more switch. With 3 trained people I 
would guess this will take about 1.5 days including all tests.

My 2cts,

        Martin
