Detailed Description
Algorithm that digitizes the Monte Carlo STK hits based on a purely geometric criterion.
This algorithm assigns the energy released by single particles traversing a wafer of the silicon detector to the strips after propagating and diffusing charge deposits along the particle trajectory.
Needed event objects:
| name | type | store | optional | description |
|---|---|---|---|---|
| stkWaferHitsCollMC | StkHitsColl | evStore | no | The MC hits in the STK wafers. |
| stkWaferParticleHitsCollMC | StkParticleHitsColl | evStore | no | The MC particle hits in the STK wafers. |
Needed global objects:
| name | type | store | optional | description |
|---|---|---|---|---|
| stkGeoParamsColl | StkGeoParamsColl | globStore | yes | Geometric parameters of the STK. |
Produced event objects:
| name | type | alias | store | description |
|---|---|---|---|---|
| stkDriftDiffHitsCollMC | StkHitsColl | stkHitsCollMC | evStore | The hits in the strips of the STK. |
Produced global objects:
| name | type | alias | store | description |
|---|---|---|---|---|
| stkGeoParamsDriftDiffColl | StkHitsColl | stkGeoParamsColl | evStore | The geometry parameters of the digitized STK. |
Parameters:
| name | type | default value | description |
|---|---|---|---|
| pitch | float | 0.0050 | The pitch used for the digitization of the top SCD hits [cm]. |
| minStepSize | float | 0.0002 | The minimum substep size along the particle path within the silicon [cm]. |
| diffusionType | string | gaussianNonLinear | The diffusion model to be used [gaussian,gaussianNonLinear]. |
| packet/biasVoltage | float | 80 | The bias voltage applied to the silicon [V]. |
| packet/intrinsicVoltage | float | 35 | The intrinsic voltage of the silicon detector [V]. |
Gaussian diffusion parameters: N.B: These parameters are only available when using the naive gaussian drift model
| name | type | default value | description |
|---|---|---|---|
| packet/gaussian/holeEffDiffCoeff | float | 0.050 | The effective diffusion parameter for holes. It is expressed as a relative sigma growth per unit of distance travelled. |
| packet/gaussian/electronEffDiffCoeff | float | 0.050 | The effective diffusion parameter for electrons. It is expressed as a relative sigma growth per unit of distance travelled. |
