9:23 Mise en chauffe
Nombreux pb vide dans health check
Acces casemate pour verification polarite RI-C2/DG/BPM.02 pas de probleme trouve.
Observation des soufflets pres de RI-C2/AE/DP.04 ils semblent legerement deformes mais pres de RI-C1/AE/DP.01 aussi.
11:30 Tentative de demarrage mais probleme temperature eau...
12:00 Intervention Maher. Demarrage possible.
Pb declenchement wavecatcher... Resolu (le serveur etait plante)
14:00 BPM polarity studies
15:30 Measure frequency
16:30 To to steer the beam around the chamber
18:20 Stop

Programme de la prise de données du 8/06:
0) During warm up:
0a)check physically BPMs where there seem to be a polarity issue (needs 2 persons, a battery and a multimeter).
0b) CHeck vacuum chamber around RI-C2/AE/DP.04
1) Transport to TL/FC.01 (TL/DP.01 off). Record FC signal
2) Transport to TL/SST.02 and TL/BPM.02. Record BPM adc signal while closing dispersion (for Mouad's studies).
3) Transport to EL/FC.01. Record FC signal and compare with TL/FC.01. If needed swap filters and compare again.
4) Activate position feedback on TL/BPM.02
5) Inject in ring, no RF power. Record with high res oscilloscope travel time for different magnets settings. If needed use a mixer.
6) Study the effect of correctors around RI-C2/AE/DP.04
7) Use extraction kicker scan to measure beam travel time after several turns
8) Finish BPM polarities study
9) Repeat (5) and (7) with different RF powers at 2 different frequencies (500.0202MHz and 500.4MHz). Look at oscillations on TbtX and TbtY vs frequency.
