Tables 1-6 summarize electrical CABLE requirements, optical FIBER requirements, WATER line requirements, AIR DUCT requirements, RACK requirements, and OTHER space requirements for the SVT. These requirements are justified below. In estimating the cross sectional area of cable paths required, cables were treated as having square cross sections of area .
For each RACKS to individual READOUT ELECTRONICS location (i.e., 24 separate paths, 12 to each end of the TPC) the integrated cross sectional area of the required CABLES (11 CABLES) is 3 .
All CABLES entering each end of the SVT SUPPORT STRUCTURE (360 CABLES) have an integrated cross sectional area of 35 . WATER lines require an additional 6 of space in each end, so at least 41 is required through each end of the SVT SUPPORT STRUCTURE. The cross sectional area of a 1 in wide ring with an outer radius of 7.8 in (the radius at the small end of the ``CONE'') is 46 .
Two OPTICAL FIBERS from each of the 24 READOUT ELECTRONICS locations go directly to DATA ACQUISITION in the COUNTING HOUSE. Sharp turns must be avoided and each of the 24 paths requires a cross sectional area of 0.1 .
Two WATER lines (1.5 in, inside diameter, each) must connect the supply side of the SVT HEAT EXCHANGER (located outside the experimental hall) to two WATER MANIFOLDS near one end of the SVT SUPPORT STRUCTURE; from each MANIFOLD 5 -- (0.75 in, outside diameter, each) WATER lines enter the SUPPORT STRUCTURE (10, total) and go to another WATER MANIFOLD near the SVT. An identical requirement exists at the other end of the SVT in order to return the water to the HEAT EXCHANGER (via a low pressure water system located on the NORTH PLATFORM, THIRD LEVEL). This water cooling system must be independent from any other cooling system. SPACE is required for the mechanical part of this system.
Large AIR DUCTS must be located at each end of the SVT SUPPORT STRUCTURE for SDD surface cooling. These DUCTS connect to the SVT LIGHT PLATES which make the SVT light tight. The SVT AIR CONDITIONING system must be independent from any other air conditioning system. SPACE is required for the MECHANICAL part of this system.
NOTE: A multi-conductor (number of conductors to be determined) must run from the RACKS to the Capacitive Displacement Measuring System (CDMS) located on the SVT ladders.
NOTE: In addition, WATER must be provided to each of the 24 READOUT ELECTRONICS locations for electronics cooling. The TPC WATER system which cools the TPC READOUT ELECTRONICS will provide the SVT READOUT ELECTRONICS cooling WATER. Each (24 total) READOUT ELECTRONICS area will generate about 100 Watts of power.
