Front End Boards (FEBs)

Information about the Front End Boards (FEBs) developed and produced by Columbia for the readout of the ATLAS liquid argon calorimeters.

Photograph of one FEB, with many of its components labelled. A total of 1524 FEBs is required to read out the entire LAr calorimeter system.
