Electrode Transmission Line Corrections to the ATLAS Forward Calorimeter Pulse

The ATLAS Forward Calorimeter liquid argon electrodes are short, coaxial transmission lines which cannot be impedance matched to the readout. Because they are short, such an electrode can be approximated by a capacitor. But a full treatment of the electrode as a transmission line changes the shape of the current pulse in small but significant ways and contributes to the timing resolution.
