Cables

Tunnel

The cables are installed in dedicated cable trays running parallel to the beam line. The cables for the B stations enter the LHCb cavern alongside the QRL. The cables for the F stations enter the cavern below the sector door separating UX85 and RB86. For each station, the following cables are installed.
Function SCEM Number of cables / station Connectors
HV 04.31.51.555.2 10 SHV female (09.41.25.130.5)
Signal 04.61.11.265.8 5 N male (09.46.11.800.1)
LED 04.61.11.225.6 2 BNC male (09.46.11.700.4)
Motion system (NE18) 04.21.52.130.6 1  
Grounding 04.08.61.950.9 1  
In addition, there are four plastic tubes (Festo PUN-8x1,25-BL) per station supplying the compressed air for the motion system. The cables and tubes from the B stations end up at the front-end crate location in the UP84 tunnel. The cables and tubes from the F stations end up next to the UX85/RB86 sector door.
