Rack Layout in USC55 (version 7.5)

Both floors are shown. Racks are installed out to #11, 15 on S1,2. Row A is closest to the shaft. Racks 0 (S1) and 1 (S2) are closest to the interaction hall (UXC55).  Rack rows are spaced 1.5 m front face to front face (B-C,D-E,F-G,H-J)) and 1.0 m rear face to rear face (A-B,C-D,E-F,G-H,J-K). *There is a 30 cm underfloor structural beam between racks 8 & 9 (and 17 & 18 on S1). #There is a 30 cm gap between racks S1C08 and S1C09 and also between S1F08 and S1F09 for a vertical structural column. %There are holes between the floors located at E03, E05 and F05. RED RACKS HAVE CRITICAL LENGTH FIBERS TO THE DETECTOR. GREEN RACKS HAVE NON-CRITICAL PATH FIBERS TO THE DETECTOR. DAQ RACKS ARE BLUE. GREY RACKS ARE RESERVATIONS. Definition of abbreviations. Information about racks. Rack Wizard (rack entry tool). Descriptions of S1 Racks. Descriptions of S2 Racks. PC entry tool.
Green Shaded Racks have automatic fire suppression. Yellow-shaded racks are standard PC racks
