[Eesic] Hall A reconnects

[Peter Anthony Francis]

Good Morning Everybody,

After receiving Ed Folts email about reconnects for Hall A, I looked 
into Hall A's new beam line configuration.

Ed Folts response to new Hall A Beam Line.
  Hi Pete
  The Hall A beam line is going back to its original configuration prior 
to G2P. The only difference is an additional BPM in the upside down 
girder upstream of the main girder which I believe is a Musson BPM. As 
far as I know we don't have a good drawing for this accept for an 
assemblt dwg. I can get that if you want.
thanks
Ed


The Hall A Beam Line configuration prior to G2P I have attached as file 
Scans12524.pdf


I forwarded the drawing to Ed Folts to see if this drawing is correct 
for Hall A Beam Line and this is his response.

Were we are working yes. However the EP device has been removed at the 
far upstream end of the beam line and the calorimeter has been moved 
from the girder to the EP position. A new raster will also be installed 
at the EP position but it is yet to be designed.
thanks
Ed


So.....I don't think there is a completed Hall A beam line configuration 
as of yet but the document that I have attached, I'm assuming from ED is 
very close.

If I get any better drawings I will forward them to EESIC.
