The design of the cable trays is almost final. Inside the tunnel, you can see an overview of the trays along with a view along the tunnel and a view looking into the ports.

The trigger signal and HV cables will be carried by a set of trays running at 11 ft height along the beam line. This is part of the beampipe protection system. A tray runs straight out from the IP connecting this set of trays to one port.

A second tray runs along the +Z face of the magnet and feeds the far left port. This tray will carry trigger and TOF HV cables.

The 2 ft tray running along the tunnel near the wall will carry TOF timing and ADC cables. It starts above the TOF walls at a height of 13.5 ft and runs 90 ft down the tunnel. At that point, the cables drop down to a second tray at about 10 ft high and return to feed the first two ports on the left.

The far right port is for power and water-cooled bus. The two middle ports are for future use.

Outside the ports, the cable spill out into 2 ft trays which run horizontally. About half way down the berm, there is a set of sideways trays. Most of the TOF cables will travel to the left and then go down a second set of angled trays and under the house. They will enter the electronics room through holes in the floor. Tow of the trays leading under the house are fed by T's on the sideways trays and two follow directly from the trays out from the ports.

In addition, the straight-shot tray from the IP continues horizontally, entering the counting house through the back wall near the ceiling of the electronics room. This tray ends near the Trigger rack with is just to the right of center in this room.
