===== Calibration Board 3 (FE # 4) =====
==== Resistance 100 kOhm ====
=== Pedestals ===

 * Aucun cable d'injection connecte

   * Piste par piste , 737733
   * Tous ensemble ,737735, 737738. Tres peu de bruits, tous alignes a 361

 * On allume le gene, rien de connecte
   * 737739, un pic de bruit apparait!
   * On connecte la masse du gene au plan superieur

 * Des masses de partout!!!

=== Injection ====

* 500 mV 737769

canal 2 395

canal 14 390 

* 200 mV 737770

canal 2 371
canal 14 370

canal 14


{{::calibration_board3_piste71.jpg?200|}}

On obtient 12.3 mV par VTH count du cote large
et 14.7 mV par VTH du cote oppose

Donc entre 6 et 7 fC (facteur 2 du au partage des charges) par DAC.

Le piedestal mesure est a 362, extrapole a 355 on est sans doute pas completement lineaire a basse injection

Si on regarde le rapport des signaux transmis et proche on a 


{{::injection_5pc_cote_large_pcb_fin--00000.png?200|}}

On retrouve le rapport mesure de 12.3/14.7 ~ 84 %

=== Etude de l'efficacite ===

Seuil minimal 368 => environ 7*7.3=51 fC

Injection cote large, en comptant un coup de "turn on" on s'attend a etre efficace du cote injection a

(369-355.26)/0.0814 = 169 mV

et des deux cotes a

(369-356.0)/0.0679 = 191 mV

On obtient:

Delat T -17.6 et -0.5 donc 17.1=2 x dt => dt =8.6 compatible avec la mesure des pulses (8.3)

On change de piste 73
 
et on s'arrache la tete, le delai trigger / pulse doit etre regle a 2.5 ns pres car on peut tomber sur le temps mort du TDC....

Run 737813 , 250 fC cote etroit on n'est pas pleinement efficace des deux cotes (78 %)

737818 200 mV de l'autre cote

737819 210 mV

737820 220 mV (69 %) 

On a donc quasiment 50 fC d'eccart entre les deux pistes... A comprendre est ce du a un probleme de gain ?

On des burst de bruits.... ce qui explique les fluctuations

Si on met le seuil a 496 et 200 mV

Resolution la plus mauvaise observee ~ 0.3/8.6 => 5 cm 

Su la <imgref calib_ipnl_fe2_150_71_eff> on observe:

  * Seuil minimal de detection electronique => 90 fC, Q injected 180 fC

  * Seuil minimal de mesure X,Y  Q injected 200 fC

Les résultats sont quasiment identiques à ceux mesurés avec le Board 3 (FE #4)
