I have designed new cable supports for the new ribbon cables running up the side of the tables in the vacuum chambers.
The clamps that I have designed (shown in basic sketch attachment 1) will secure the cable at each of the currently used cable supports.
The support consists of a backplate and a frontplate. The backplate is secured to the leg of the table using a threaded screw. The frontplate clamps the cable to the backplate using two screws: one on either side. Between two fascinating points, the cable should have some slack. This should keep the cable from being stiff and help reduce the transfer of seismic noise to the table.
It is possible to stack multiple cables in one of these fasteners. Either you can put two cables together and clamp them down with one faceplate or you can stack multiple faceplates with one cable between each faceplate. in this case the stack would go backplate then cable then faceplate then cable then the second faceplate. this configuration would require longer screws.
The exact specifics about which size screws and which size plates to use still have not been measured by me. But it will happen
