| Settings for the inclined EM calorimeter. | ||
| The barrel is filled with liquid argon. Passive material includes lead in the middle and steal on the outside, glued together. | ||
| Passive plates are inclined by a certain angle from the radial direction. | ||
| In between of two passive plates there is a readout. | ||
| Space between the plate and readout is of trapezoidal shape and filled with liquid argon. | ||
| Definition of sizes, visualization settings, readout and longitudinal segmentation are specified. | ||
