The GBT Control Room

The Control Room for the GBT is a couple of miles away from the telescope and is very specially built to be shielded from all outside RFI (Radio Frequency Interference). As much as possible, the room itself is electrically grounded so that the computers that run the GBT do not interfere with the very weak received signals nor are influenced from outside.

The copper plating on the walls and wire screens on the windows that effect the electromagnetic shielding of the Control Room. This essentially makes the entire room a Faraday Cage. The windows were installed at the insistence of the Operators so that they can visually see the GBT (which is hidden by the wall between the two windows here). The presence of windows makes the shielding procedure more difficult.

Two of the Operators of the GBT. The fellow on the right had not only heard of Bemidji, but had actually been in Bemidji. (He wanted me to know, and now you know. Us Graybeards stick together.)
