plane together with its sub-carrier and the guide rail. The upper guide rails serve as tilt prevention mostly, see exploded view in the right part of figure 5.8. Figure 5.8.: Left: lower edge of one double plane together with its sub-carrier connection to the guide rail. Right: Upper edge of one double plane, displaying its connection to the upper guide rail. Figure 5.9 illustrates the use of the second detector frame for maintenance purposes. The front sides of both frames are constructed such, that the sliding rails of the both frames can be connected easily. The double planes can be moved from one to the other frame individually, thus giving space for maintenance purpose. When all 30 double planes are inserted into one housing, the weight of NeuLAND amounts to about 32 tons. The detector frames and the fully-assembled detector will be moved using air cushions. Figure 5.9.: The two NeuLAND frames, arranged for moving double planes. On the left hand side, the front-sides of both frames are put to minimum distance, on the right part half of double planes have been moved to the second frame. 72
5.4. Peripheral Systems 5.4.1. Read-Out Electronics - TacQuila NeuLAND will be built in a modular manner, composed of 30 double-planes. Each double-plane will be independent with respect to its supply and read-out systems. In figure 5.10 the present layout of the support boxes in the four corners of each double plane is detailed. 6 5 4 A D D 84 A ( 1 : 10 ) 496 3275 C C B B t
