As for the dilution refrigerator, the design of the modifications of the cryostat platform and the pumping lines can be started as soon as the magnet dimensions are fixed. In case that the target position will be changed, the pumping lines to the dilution refrigerator have to be modified. The gas handling system of the magnet has to be redesigned and rebuilt for the part not included in the magnet delivery. This is a major work and requires in addition to the manpower of the universities specific help of CERN technicians. The helium liquefier in hall 888 must be started before the testing of the magnet will start.
