sPHENIX MAPS tracker discussion

[John Haggerty <haggerty AT bnl.gov>]

Hello,

We finished the last ESRC review on Monday, and so you are indeed next.  
BTW, we can move the dry run to your convenience, but we can't easily 
change the Nov 15 review.

I think we will limit the scope of the review to not include the 
detector installation, because I suspect that the MVTX and INTT 
installation will engender a lot of discussion along the lines of "You 
mean it's only 2 mm from the beryllium?" so we will probably have to 
leave that for another ESRC meeting, and once you have the movie of the 
installation mock-up, that will probably be much quicker.

If we leave that out, then I think we're dealing mainly with electrical 
hazards and practices.  So you need to show that the cables and 
connectors are rated to carry the voltages and currents, they are 
(flammability) rated appropriately for the cable trays, PC boards are 
made of FR4, and you have appropriate interlocks, fusing, and current 
limits. You should have some slides on cooling.  Any commercial 
electronics needs to be either UL listed, or you have top explain that 
you have or will have it inspected by a lab Electrical Equipment 
Inspector (EEI).

You don't need to cover AC power distribution, or the generic interlocks 
provided by Joel, as they have been reviewed.  You don't have to cover 
electronics in the rack room, we'll also do that at a later time in a 
more general way.

If there are other hazards that I've forgotten, let me know.  I should 
mention that due to a number of recent electrical safety incidents in 
CAD that the audience may be lively.
