| 19 | // <h2>AliTPCFCVoltError3D class </h2> |
| 20 | // The class calculates the space point distortions due to residual voltage errors |
| 21 | // on the Field Cage (FC) boundaries (rods and strips) of the TPC in 3D. It uses |
| 22 | // the Poisson relaxation technique in three dimension as implemented in the parent class. |
| 23 | // <p> |
| 24 | // Although the calculation is performed in 3D, the calculation time was significantly |
| 25 | // reduced by using certain symmetry conditions within the calculation. |
| 26 | // <p> |
| 27 | // The input parameters can be set via the functions (e.g.) SetRodVoltShift(rod,dV) where |
| 28 | // rod is the number of the rod on which the voltage offset dV is set. The corresponding |
| 29 | // shift in z direction would be $dz=dV/40$ with an opposite sign for the C side. The |
| 30 | // rods are numbered in anti-clock-wise direction starting at $\phi=0$. Rods in the IFC |
| 31 | // are from 0 to 17, rods on the OFC go from 18 to 35. <br> |
| 32 | // This convention is following the offline numbering scheme of the ROCs. |
| 33 | // <p> |
| 34 | // Different misalignment scenarios can be modeled: |
| 35 | // <ul> |
| 36 | // <li> A rotated clip scenario is only possible at two positions (Rod 11 at IFC, rod 3(+18) at OFC) |
| 37 | // and can be set via SetRotatedClipVolt. The key feature is that at the mentioned positions, |
| 38 | // the strip-ends were combined. At these positions, a systematic offset of one strip-end in |
| 39 | // respect to the other is possible. |
| 40 | // <li> A normal rod offset, where the strips follow the movement of the rod, can be set via |
| 41 | // SetRodVoltShift. It has a anti-mirrored signature in terms of distortions when compared |
| 42 | // to the rotated clip. This misalignment is possible at each single rod of the FC. |
| 43 | // <li> A simple rod offset, where the strips do not follow the shift, results in an even more |
| 44 | // localized distortion close to the rod. The difference to a rod shift, where the strips follow, |
| 45 | // is more dominant on the OFC. This effect can be set via the function SetCopperRodShift. |
