Here is a barrel hadronic calorimeter at radius 310 cm, extending to +- 380 cm. The energy resolution is 120%/ (the constant term is 0), the angular resolution on the shower-axis is 3 degrees in ; in phi it is 3.75 degrees. The resolution on the shower start-point is 7.22 cm in both R and z. The efficiency is 95 %, and the threshold is 0.4 GeV. It is made of iron (A=26), is 5.45 nuclear interaction lengths deep, and have a total of 52.0 radiation lengths. There is also 5 cm of material in front of the calorimeter. It is also iron, yielding 2.9 radiation lengths, and 0.3 interaction lengths. This represents a course-grain ("Tower") hadronic calorimeter.

Here is another barrel hadronic calorimeter with the same geometry, energy resolution, material, efficiency and threshold. It also has the same material in front as the example above. It is modular in and z (SHOWER_POS_MEAS=1), with 12 modules in and 10 in z.
This represents a course-grain ("Tower") hadronic calorimeter.
