[Swreq] screen request for A-PEX in HALLA

[yves roblin]

A-PEX is a test experiment that is going to start running beam with the 
septum magnet in a specific configuration July 1st.

We requested (OPS/CASA) that they provide us with a readback on the set 
point of that septum magnet. This magnet is placed behind their target
and is controlled by them. In normal operations, it does not affect the 
beam delivery to the dump  and hence, is not controlled by OPS. In this 
particular
test, it is going to be run in a way that will steer the beam. We need 
to have a read back in the control room.

Hall A told me that the readback is the one from teh bigbite: MBIGBOXM

This is a current readback. The request is that one has to have that 
present on one of the screens. Perhaps the HALLA wall screen?

It should be labeled Hall A septum, the PV is MBIGBOXM.


PS:

They are also installing a new corrector in the beam line, 80 
centimeters upstream of their target. Simon Woods is going to do the 
cabling and indicated that he will work with software as he normally 
does to have this in the control system as well.
