General
 In the July EB it was decided to start an informal task force to look at in
details what can be done to accelerate the schedule in the first 6
months following the insertion of the barrel calorimeter.
 The task force had its first meeting 27th of July and since then has met
roughly once a week.
 The following is a summary of a possible installation sequence worked
out in the task force meetings. The sequence covers the period from
completion of the BT in July ’05 to the end of the Calorimeter A
assembly on the Truck in the beg of ’06.
 The sequence has also been implemented in a working schedule.
 All the working documents of the task force (including the working
version of the schedule) are available on EDMS at:
https://edms.cern.ch/document/490947

Starting point
 Our starting point is the mechanical completion of the Barrel Toroid in
July ’05. By this time:
 Barrel Calorimeter is ready, tested with all possible services we can
install.
 Toroid installation platforms are still in place.
 Jacks supporting the BT are still in place.
 Some Muon chambers (especially in bottom sectors 12, 13 and 14)
are installed.
 Some cable trays, Muon rails and brackets of the access gangways
have been installed on the coils/warm structure.
 Muon access gangways in sector 13 installed.
 Cryogenic lines installed in the bottom sector.

From mid July onwards
 When the BT is mechanically assembled we move on to a hectic
installation period which consists of parallel work almost all over the
detector and the cavern.
 To simplify the planning of this period we have divided the next ~4
months (from mid July) in 5 short phases that are easier to manage.
The length of the phases are from 2 to 4 weeks and they are marked
with letters A-E.
 For this presentation I have also added 5th phase (F) which was
discussed in the last two task force meetings and which covers the
period from end Oct ’05 to Jan ’06.

What else can be done during phase B
 Finish fixation of Solenoid Chimney & Control Dewar
 Remove truck A and install muon elevating platform A
 Install phi scaffolding on the surface of the barrel calorimeter
 Finish installation of the cable trays
 Start connecting up the cooling and vacuum pipes.
 Start connecting up the cryogenic lines
 Install the muon elevating platform on side C between the Truck and
BT. This is a new idea and makes it possible to assemble end-cap
calorimeter and install muon chambers in parallel on the same side.
The platform has to be installed, operated and accessed above the rail
line.
 Start installing BT busbars under the HS arches.

Phase C: From end Aug till mid Sep ’05.

We can now start 4 main activities in parallel:
1. Calo and ID services installation along the Barrel and exit at z=0

Start first putting in place the radial cable supports at z=0
2. Muon Barrel installation

In the present scenario we can install chambers from both ends. Side
A platform has access to the full face. Side C platform is put in
between the BT and Truck C and has access only to sections above the
rail height. Access gangways are installed where possible.
3. Cryo lines connections + cryo services installation
4. End-cap Calorimeter C assembly on the Truck


Cable trays z=0 : First operation. Install all the support structures and
z=0 cable trays at z=0 sector by sector in the order 5, 13, 3, 7, 9, 1

Install pipes from z=0 to cooling units (cal) and distribution racks (ID)
on HS and make connections at z=0.

Muon Barrel installation, step 1
Chambers before removal of the BT top platforms
Must wait for 1 month before re-tightening the BT bolts and removing
the platforms. Cannot start installing BMS chambers in sectors 4 and 6
before the platforms are removed -> try to do something else in
between.
BOS chambers: all on normal rails (If simpler install all from side A)
BIS & BIL: If possible, insert first 3 chambers per side and park at large Z
till services are in place. Can now be inserted from both sides no need
to jump over at Z=0. The chambers can be later moved into their final
positions without using elevating platform.


The brackets for the access gangways in the BT coil will be installed where
possible as the coil is assembled.
After removing the BT coil jacks, and the barrel calorimeter put into
position, the gangways and barrel muons will be installed as the BT
assembly platforms are removed.

Connection of Barrel Cryogenic lines
 All the cryogenic lines inside BT are already installed while building it up
or in phase A. In the same way all the lines along the Barrel
Calorimeter up to z=0 are installed already on the Truck.
 As soon as the calorimeter is moved inside to its final position we can
start connecting up the lines at z=0:
-
LAr and LN2 lines on top of the cryostat
FT vacuum lines on top
LAr dump line on bottom
Insulation vacuum lines on bottom

Goals for phase C
At the end of phase C :
 All barrel calorimeter cables are installed (but in many sectors still
not connected up)
 Installation of the ID cables from PP1 to PP3 has started.
All possible BIL,BIS chambers are either in the parking position or
in the final position. All BOS chambers in top sectors installed.
The cryo-ring is being connected in sector 5 at Z=0.

Muon Barrel installation, step 2
Chambers after removal of BT top platforms
First step: remove BT top platforms. Then, install BMS chambers in sectors
4 and 6 first after which aim at completing sector 5 asap.
BMS chambers in sectors 4 & 6:
Will be brought in from Sector 5.
Sector 5: As soon as calo & ID services installed at z=0 finish BIL. When
BMS in sectors 4 & 6 done install all BML, EIL4 and BOL. Might still
need to leave a gap for services at Z=0.
Sectors 3 & 7: Install all BOL (possibly on extended rails to leave a gap
for services). The first 3 BML chambers could also be installed at this
stage but it seems better to wait and install full sectors at one go once
the ID services through Muons are done and all BIL chambers installed.

Removal of lateral platforms & Muon installation
 Lateral platforms provide good access in many areas and should
therefore kept in place as long as possible. However, they need to be
gradually removed to:
give space for the gangways and chamber installation in lower
sectors
give space for the installation of the last BOF/BOG chambers
between the feet after which we can put back the HS extensions
which the flexible chains in sectors 11 and 15 will be supported
from. The chains in turn must be installed before the Muon chamber
installation in these sectors can be completed (access still to be
sorted out).
 After removal of the lateral platforms all the rest of the BOS and BOL
chambers can be installed on side A, BOS chambers possibly also on
side C.
 Chambers in the inner layers are still dependent on the ID services
installation and must wait for the installation of the ID services through
the gaps in Muons to PP2s.

Summary

“Installation Summer 2004 task force” has worked out a schedule proposal for
the 6 months following the completion of the BT.

The schedule is now much more detailed than before, especially on the
installation of services.

The main difference in the sequence w.r.t previous version is that on both sides,
A and C, the installation of the Muon barrel chambers is done partially in
parallel with the End-cap Calorimeter assembly, and on side C the assembly of
the first Big Wheel is started when the barrel chambers installation is still going
on.

The rest of the schedule has not been discussed in the task force, but I have
now scheduled the assembly of all four Big Wheels on side C before lowering
End-cap Toroid C. On side A the sequence is in reverse order.

In the schedule all the Big Wheels on side A are assembled before closing the
beam pipe (March ’07). However, in case of problems and delays we must be
able to assemble the Big Wheels also with the beam pipe closed.
