||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.
