[Tpe] base plate for calorimeter -TPE 2010

[David Kashy]

Hi Brian,
Here is the plate. Be sure to center the CG not on the plate, but on the 
pattern of 8 holes that are offset from the center.

You can use any or all of the holes in the four corners to mount the 
calorimeter, and you can put a spacer plate between our plate and the 
calorimeter too.

Please note that the beam should go from bottom to top of the page so 
the 8 hole pattern is toward the downstream edge of the plate.

As a follow up on the chicane tunnel, I believe we had two aluminum 
plates ~3/4" or 1" thick about 4'x4' square for the bottom of the tunnels.

Doug, Will you please take a look for those aluminum plates as we will 
need them again.
when you find them let me know. We will likely want to get two more 
because this time we probably will not use any borated polyurathane 
block and that was the structural material for the tops last time. We 
also will probably need more lead bricks or concrete block or both. I'll 
try to summarize the expected max quantities at a later date...


Thanks
Dave
