Placement of I-bars in waiting position
The Two I-bars on the C-side are shielding the
access to the ITS-Service Chariot Connections.
? During ITS installation, a set of two I-bars
is installed on the A-side (Shaft Side).
Another set of I-bars is waiting on the C-side.
Once the TPC is in final position, the load is
transferred to the C-side I-bars and the
A-side I-bars are removed.
The Backframe Platform will be installed next
week. How to hold and handle the I-bars will be
investigated at the same time

Transfer Rails
Transfer Rails (Between DF and SF) must be placed
in the BSF in a parking position before the DF
is put in place

• Integration test was done without BSF !
  Installing rails after DF was possible. This is
  not the case in the final configuration.
• A test of the the installation of the transfer
  rails in the L3 magnet will be performed within
  the next weeks (August)
• Check installation procedure.
• Check if clearance to BSF is sufficient.

Access for Installation of Jacks
An access platform elements are hanging on the
TPC rails and they can also slide on the rails.
They are designed to fit between TPC and fixation
piece.

Displacement of TPC from DF to IP
During the movement of the TPC, the relative
position of SSW and TPC must be monitored ?
Simple mechanical device. The position of the
TPC will me monitored by the Surveyors. The
x,y,z, coordinates of the outer (and possibly
inner) reference rods on the shaft side will be
used to determine the position of the TPC. It is
not possible to install a useful survey station
on the C-side.
6
Alignment of TPC with Beam Axis
Once the TPC is in the final position, the TPC
axis is aligned with the beam axis. Again, only
the x,y,z, coordinates of the outer (and possibly
inner) reference rods on the shaft side can be
used to determine the position of the TPC.
7
Installation of DF platform
While the TPC is aligned in the final position,
the Platform for the ITS table in the DF is
installed. During the integration test we used
concrete blocks. Since in the cavern there is a
false floor with services underneath and since
the platform must be large than during the test,
a scaffolding type platform will be set up.
8
Installation of 1st ITS rail section
Two 6m sections of the ITS rails are inserted
through the TPC and fixed by the ITS rail
fixation points on the frontabsorber. Then, the
fixations points are slightly opened to allow the
ITS rails to move to the parking position
together with the TPC. Since we assume that
after movement of TPC to parking position and
back to the IP the TPC ends up in the same
position, the above procedure will make sure that
the ITS rails are well aligned with the TPC when
it moves to the IP.
9
Displacement of TPC from IP to Parking Position
(!! 4600mm !!)
R position of SSW and TPC must be monitored ?
Simple mechanical device. The transversal
movement of the TPC will again me monitored by
the Surveyors. ThisTPC movement will tell us how
the beampipe will be deformed during the final
displacement to the IP.

Installation of Spaceframe Platform
The platform elements beween TPC and
frontabsorber for ITS installation will be
installed.
