On aligne dans QP1 et QP3 et on regarde pour une variation de +- 1A la derive sur TL/BPM.01
valeur nominal QP1-QP3 (0.1A, 3.4A, -3.4A)
autour de QP1-QP3 à 0 pour l'alignement :
* valeur nominal BPM initale (0.3mm, -0.3mm)
* QP3 +1A : (0.3mm, -0.1mm)
* QP3 -1A : (0.5mm, 0mm)
* QP1 +1A : (0.4mm, -0.1mm)
* QP1 -1A : (0.3mm, -0.2mm)
* valeur nominal BPM finale (0.3mm, -0.2mm)
autour de QP1-QP3 à aux valeurs nominales pour l'alignement :
* valeur nominal BPM initale (0.4mm, 0mm)
* QP3 +1A : (0.3mm, 0mm)
* QP3 -1A : (0.4mm, 0mm)
* QP1 +1A : (0.4mm, 0.mm)
* QP1 -1A : (0.3mm, -0.1mm)
* valeur nominal BPM finale (0.3mm, -0.1mm)
*** We go to the ring ***
No Steerer and we can transport to the ring. Alignement used : QP1-QP3 @nominale current
==> no loss of charge.
==> good beam on last screen
==> I suggest to used this alignement : saved in recipe "all_20241025_19_18_14"
==> with steering impossible to enter in the ring when at 0 on TL/BPM.03 and TL/BPM.04 (on axis beam). Why ? Ring configuration ? Kick from Ring magnets or EP ? Especially in vertical.
==> by setting the nominal current on the steererqs (of TL) we can inject in the ring. The 2 alignement of QP1 - QP3 seems to be close enougth.
*** Scan coil Vs beam dim at TL/SST1
