** Tuned UxV method requires: **

* strip fired if ADC > ped+15

* SMD hit patterns: 000000xx000000 or 000000x000000

* UxV intesection points is in 0.6^2 of fiducial area of a tower

* tower MIP condition: ADC in [0.5,2]*MIP response (green lines on spectra)

* preshower1,2 MIP condition: ADC in [12,112]

* post-shower MIP condition: ADC in [6,106]

X-Y position of all MIP points (after mapping correction and masking of dead towers/tiles - described below) (PS.gz) .
View from the outside, sector numbering clock wise.
Magenta triangles mark 3 dead towers, red spots reflect 12 masked pre/post shower tiles.

* Towers : 01TA05 < -- > 01TA04

* pres2 : 01QA11 < -- > 01QB02

This needs to be changed in the DB. Note, there is few more questionable towers but w/o gain correction it is hard to assess if anomalies are caused by the mapping.

The red-dashed line in the tower spectrum marks expected MIP response for the ideal calibration of 60 GeV ET @ 4096 ADC.

All 4 leyers are working properly | Post-shower is broken |
---|---|

tower spectrum has too large pedestal | after swap of towers A4 & A5 the pedestal is lower |
---|---|

Table with plots (PDF) showing reponse of all 720 towers/pre/post to MIP:

PLOTS | PLOTS *) | broken elements | |
---|---|---|---|

sector 1 | spectra | yield | tower C6, post D12 |

sector 2 | spectra | yield | all works |

sector 3 | spectra | yield | post E12 |

sector 4 | spectra | yield | all works - within statistics |

sector 5 | spectra | yield | pres1: C10, D11, E2; pres2 E3 |

sector 6 | spectra | yield | tower A3 |

sector 7 | spectra | yield | tower C5, post D3; tower B9(x=17) had gain 40% too large -is fine |

sector 8 | spectra | yield | pres1 C11, post D7,D9,E5
funny pattern - but for now ( w/o gains) OK |

sector 9 | spectra | yield | all works |

sector 10 | spectra | yield | pres2 E10 |

sector 11 | spectra | yield | pres1 D3(x=49) has very low gain, but all OK within statistics |

sector 12 | spectra | yield | all works
note tower C5 with ped @ ADC ~230 works fine |

A - MIP X-Y position after all cuts (red blob due to masked post shower D12)

B - MIP yield from tower spectra after all cuts. The key to X-axis index is below the plot

C - MIP X-Y position only SMD cuts before tower fiducial cut (input).

D - MIP yield from B dived by # MIPs avaliable from SMD & fiducial cut.
