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.
