9h demarrage modulateur et schillers

Cyclage aimants

Asservissement laser ON

10h25 : Scan charge phase

11h Reglage linac

LI/ICT.01 50pC avec iris=2mm

12:00 Ligne deviee: Faisceau instable

12:30 Camera timing scan on TL/DG/SST.01 (see attached plot) + Trying to fix trigger issue on TL/DG/SST.02

14:00 Single shot OTR!!!

15:00 Faisceau stable sur TL/DG/SST01 avec steerer ON mais instable sur TL/DG/SST.02

=> Faisceau instable en energie

16:00 Rechargement de la recette du 19/9 a 21h25 => faisceau dans l 'anneau

16:30 Septum voltage 97V

Debut du second tour oberve sur le scintillateur!

Septum optimum timing=-38us

Kicker timing -7.250us (see attached plot: No effect on RI-C1/BPM.02, strong effect on RI-C1/BPM.03, medium effect on RI-C2/BPM.01)

19:00 Arret

Le modulateur n'est pas tombe de la journee.

 

 

 

 

 

 

 

 

 

 

 

 


 

Plan for the beam time

1) Start the llinac

2) Scan in time camera LI/DG/SST.01

3) Re-establish beam transport to ring

4) Scan in time the septum

5) Scan in voltage the septum

6) Adjust timing of kicker by looking at induced noise on ICTs

7) Scan in time the kicker

8) Scan in voltage the kicker

9) Adjust steerers as needed...
