NeuLAND - FAIR

10. Installation procedure, its Time
Sequence, Necessary Logistics from A
to Z including Transportation
The parts for the NeuLAND submodules will be delivered to the GSI/FAIR site, where
the final assembly, testing and installation takes place. The detailed sequence and testing
procedures are described in chapter 7. For the mounting of submodules and the
arrangement of the submodules in double-planes a certain installation area has to be
allocated.
The area has to provide space for one NeuLAND detector frame, with a width of about
5.2 m, a height of about 3.3 m, and a depth of about 4.4 m (figure 5.5 in section 5.3).
In addition, space for storage of delivered scintillator bars and peripherals is required.
Racks for testing the submodules with their electronics and high voltage supplies need
to be installed. Two special mounting tables need to be provided, with an area of about
3×3 m 2 each. In total the required assembly space amounts to about 100 m 2 plus 50 m 2
for storage of submodules and peripherals close to the assembly location.
After full assembly and test of an double-plane, the double-plane has to be lifted from
the mounting table and inserted into the frame structure. This requires an indoor- or
mobile-crane for the transport of the double-plane with a weight of about 1 ton.
The time scheme foresees the production of one double-plane per month. First experiments
will be scheduled using a 20% detector, see chapter 12. We propose to move the
first detector frame from the assembly space to Cave C, after 20%, i.e. 6 double-planes
are ready to be installed. Depending on the location of the assembly area and its technical
equipment, we can either transport the double-planes and the frame individually
or all-together.
Starting with the 20% detector, NeuLAND will be gradually be built up with ready-built
and tested double-planes, while being located at Cave C. The supervened double-planes,
with their 200 read-out channels, each, will be integrated into the R 3 B DAQ system.
Ongoing cosmic calibrations, see section 8.2 will serve to monitor the implementation.
In the following we describe the procedure to move a fully mounted NeuLAND detector
from one experimental area to the other, i.e. from Cave C to the R 3 B hall. NeuLAND
with its frame can be moved to the outer area of the assembly hall using air cushions.
