sPHENIX MAPS tracker discussion

[Grazyna Odyniec <g_odyniec AT lbl.gov>]

Hi Ming and All,

Slides are very informative. 8 of them, 4 on blue BP and 4 on yellow, 
right ? So, left, right, up and down (in respect to the BP) on both sides ?

Can we get closer to the BP, for example at ~ L0 distance ? Slide 5 
shows 2 inches. It may be less background there than the L0 would get.

I assume that background may deteriorate radially. Or perhaps one can 
plan to be as close as possible to the BP?.

I was thinking that perhaps it would be good to have 2 on the L0 level 
and two 'on as close as possible' level. 2 inches may be far away from 
the "problem".

This way we will be able to help CA-D and also know what the MVTX is 
getting.

BTW: at what distance from the BP are the  CA-D monitoring devices?

My 3 cents ...

Grazyna
