DRAFT The size of the helium transfer lines can be determined from the calculated user heat loads and mass flows. Table 2.4.37 shows the diameters of two types of transfer lines, which will be used for the new facility as primary and secondary transfer lines. Table 2.4.37: Diameters of helium transfer lines. Diameter of Lines [mm] Type (Tab. 12) A B C D E Outer TL-1 40 80 40 40 50 380 TL-2 68 140 44 44 90 560 The basic helium distribution concept is that all helium coming from the refrigerator cold boxes is supplied via the transfer lines to a distribution box (cf. Figure 2.4.153) and then to the secondary transfer lines in the various tunnel sections. Figure 2.4.153: Flow sheet for a distribution box. The installation of the transfer lines and the connections to the feedboxes require large manual labour cost. The lines will be delivered in sections of about 12 m length, threaded into the tunnel and transported to their respective installation location. That location must provide the working space for welding, x-ray, pressure and leak testing and, as necessary, repairs. The FAIR system is installed in stages. The distribution system must be extended each time additional cryostats are installed. New sections may connect to sections already in operation. The connections of the helium and vacuum systems will be engineered in that way that implementation effort is minimized. The total length of the primary helium transfer lines (TL) is approximately 850 m. The primary helium transfer line will connect the refrigerators (CRYO1 and CRYO2) to three distribution boxes (DB1 to DB3) for local distribution to the separate users. Details of the distribution system and the positioning of the distribution boxes are given in Figure 2.4.154. The refrigerator, the primary transfer lines and the distribution boxes are located outside the radiation areas to simplify the installation and operating service. Inside the radiation areas space will be required for the penetrating secondary transfer lines and the individual user feedboxes. The lengths of the different transfer lines are listed in Table 2.4.38. 186
