The lower FC panels will
be installed from the beam
side towards the north.
The floor protection will be
removed as this
progresses.
This may also be an
appropriate time to
complete the installation
of the floor cryo piping.
The lower half of the
remaining FC end wall will
be installed.
The TPC installation will
be complete.

into position for the
last FC.)

The first

It may be nice for electrical connections to be biased to one side for last minute access
Access for installing the last modular panels will be a challenge
Make it a requirement for the CPA and FC to be safe to support a person on a plank
near the CPA?
Blocking underneath, in line with the standoffs, to provide support for the FC
beams?  Need to look at real situation with piping and corrugations.

Possible option for installing FC
 
Low profile light duty crane with 2 lift
points.
Crane runs on installation beams.
Crane is could be designed to be fully
or partially disassembled with access
from the downstream side of the TPC.

    Lifting Height:
    24 ft (7.32 m)
    Width - stowed:
    2 ft .75 in (0.63 m)

    650 lbs (295 kg)

Working Height*:
42 ft 5 in (13.10 m)
Lift Capacity :
350 lbs (159 kg)
Platform Height:

Options for lifting the FC panels
For ProtoDUNE and probably DUNE the lifting equipment will have to be removed
before the TCO is closed.  The last FC’s would then be assembled in place.  For
protoDUNE probably makes sense to assemble all the FC in place.

Completion of the Jura FC as
follows:
Install the upper half of
the north FC wall.
Disassemble scaffolding
in this drift area.
Install the lower FC
panels from beam side to
N side.  Removal of floor
protective panels will be
completed and the areas
are covered with the FC
panels.
Install the lower half of the
north FC wall from the
outside of drift volume.
HV can be installed at this
point.  Need to evaluate the
optimal time for this.

The upper half of the north
Seleve end wall FC will be
installed.
The upper two FC panels
may be installed at this
point.  This will block
access to the CE for two
of the APAs.
After this is complete, all
of the remaining FC
panels must be moved
and stored inside the
cryostat for the closing of
the TCO.  Also all of the
materials for closing the
TCO must be in the
cryostat prior before
beginning the closure.  Is
there enough storage and
work space available?

After the TCO is closed,
the beam side Seleve FC
will be installed.
Then the final upper FC
will be installed.
The scaffolding from the
Seleve side drift can be
removed.
After the TCO is closed,
access to the cryostat will
only be possible through
the manholes.  All
materials not in the
cryostat must fit through
the manhole.  All tooling
inside the cryostat can
only be removed through
the manhole.

This installation sequence outlines the step-by-step process for installing the lower FC panels, completing the TPC installation, and mounting the modular field cage components. It includes the placement of beams with standoffs, translation of GP planes, mounting of profiles/racetrack modules, and making electrical connections. The use of captive nuts, fasteners, and plank blocking for support and safety considerations are also addressed.
