## Specific detector setup


Configuration of the endcap disks can be done by setting values for the `FT3Base.layoutFT3` configurable,
the available options are presented in the following Table:

| Option | Comments |
| ---------------------- | ----------------------------------------------------------------------------------------------------------------- |
| `kSegmented` (default) | Currently, only OT disks have realistic implementation, for ML - simple trapezoids |
| `kTrapezoidal` | Simple trapezoisal disks (in both ML and OT), with `FT3Base.nTrapezoidalSegments=32` |
| `kCylindrical` | Simplest possible disks as TGeoTubes (ML and OT), bad for ACTS (wrong digi due to polar coorinates on disk sides) |

[ [Link to definitions](./base/include/FT3Base/FT3BaseParam.h) ]

For example, a geometry with the endcaps-only can be obtained by
```bash
o2-sim-serial-run5 -n 1 -g pythia8hi -m FT3 \
--configKeyValues "FT3Base.layoutFT3=kTrapezoidal"
```

Example O2 command to create a geometry with **segmented layers for TRK (expect for VD), FT3 and TOF:**

```bash
o2-sim-serial-run5 -n 1 -g pythia8hi -m A3IP TRK FT3 TF3 \
--configKeyValues "TRKBase.layoutVD=kIRISFullCyl;TRKBase.layoutMLOT=kSegmented;FT3Base.layoutFT3=kSegmented;IOTOFBase.segmentedInnerTOF=true;IOTOFBase.segmentedOuterTOF=true"
```

Example O2 command to create a geometry with **simple (non-segmented) layers for TRK, FT3 and TOF**:

```bash
o2-sim-serial-run5 -n 1 -g pythia8hi -m A3IP TRK FT3 TF3 \
--configKeyValues "TRKBase.layoutVD=kIRISFullCyl;TRKBase.layoutMLOT=kCylindrical;FT3Base.layoutFT3=kTrapezoidal;IOTOFBase.segmentedInnerTOF=false;IOTOFBase.segmentedOuterTOF=false"
```

### Output of the simulation
The simulation will produce a `o2sim_Hits<DetID>.root` file with a tree with the hits related to that detector.
