Endcap Calorimeter Prototype 
This is another view of the FFTB corridor looking upstream. The vantage point is upstream of the drift space shown in picture 2. In the area beyond the ramp, 220 V AC power is available. The distance from the 220 V AC service to the electronics racks is approximately 60 feet. SLAC may extend the 220 V AC service through conduit to the T-438 drift space.
