View from Outside the Linear Accelerator at Stanford University. It is a 2 mile above ground
structure containing powering, security, and facilities for the LINAC laser buried 30ft deep
directly below the structure. Buried 30ft below ground to protect against radiation..
View from inside sector 28 of the above ground section at the linear accelerator it is
approximately ¼ of a mile in this direction.
Section of cable tray that runs along the outer walls of the above ground section of the LINAC
being pulled out of the trays to feed equipment in the center of the above ground structure.
One of the many racks managing the fiber used for security, timing and other jobs that we are
required to document with Bentley Inside Plant
SLAC employee I trained this week pointing out a fiber patch panel we will need to document
with Bentley Inside Plant
Retired coaxial plant mounted to this frame formerly used for security camera signal replaced
by fiber over the years
Stack of 3 – 24in wide steel cable trays we are required to document in Bentley Comms.
These trays run in various configurations with various parts and pieces throughout the entire
2 mile length of the LINAC. The Comms Duct module is being used for this currently in a
“hybrid” fashion. More functionality will be required in Comms to accurately depict this type
of facility however.
Note the curved structure coming from the top of the ceiling dropping to the top of the large
frame structure. This is a “cascade” piece connected to the cable trays running along the walls
to support large amounts of varied cable types that we need to account for in Bentley Comms
View from inside sector 28 of the above ground section at the linear accelerator it is
approximately 2 ¾ miles in this direction.
Snapshot taken of a glass front rack that will be documented in Bentley Comms ISP module
containing fiber patches and timing gear.
View from the outside of the above ground facilities covering the 2 mile long LINAC. This shot
was taken outside sector 28.
This photo is of a 30ft “riser” location at sector 28-17. These 30ft holes are located at 30ft
intervals the entire length of the LINAC. The fiber we are tasked with documenting drops
down these risers from the wall mounted cable trays with the use of cascades at many
locations. We are required to document these locations where fiber drops 30ft below to
where the laser is located. The tarp like filling between pipes is a radioactive shielding that is
required fill at all riser locations.
This photo is of a 30ft “riser” location at sector 29-1. These 30ft holes are located at 30ft
intervals the entire length of the LINAC. The fiber we are tasked with documenting drops
down these risers from the wall mounted cable trays with the use of cascades at many
locations. We are required to document these locations where fiber drops 30ft below to
where the laser is located. The tarp like filling between pipes is a radioactive shielding that is
required fill at all riser locations.
This is a remnant of the retired coaxial network replaced by fiber in recent years. This is a 4
port 20db tap location. We could have done a nice job with the coax layout 
