Beam to RI-C2/BPM.05
Problem with injection kicker. Not triggering and DS says Charging power supply is OFF. Maher came to solve the problem (14h). Most probably this was a reason of only 1 turn during the last days.
15h Studies on the DPI and SEPT on the injection (1st BPM x-orbit). Compared to yesterday run, we see the good response on change of the DPI ans SEPT. The first BPM is at +(4-6) mm.
Without injection kicker, beam is lost after ~1 turn.

Studies on the Ring revolution frequency | |
Goal: understanding of teh beam natural revolution frequency. Study the effect of the dipoles.
We have started from the previous setting of the machine. Then we loaded the settings from last december and received better storage. RF cavity is OFF.
By working with the spectrum analyzer, we understood that previous measurements very probably were affected by the noise coming from the synthetizer, so the frequency measured corresponded to the synthetizer frequency.
At the same time, during the investigation, apart of the false peak given by the synthetizer frequency, there was some signals (difficult to interpratete) aroung 500.4 MHz. Investigations are ongoing.
In parallel, we are checking the BPM cabling convention by using the beam to be sure about the orbit readings.
Study of signal on scope:
Yellow: Losses monitor
Green: Sum of 4 electrodes RIC2/BPM.06
Blue: Long open cable (background pickup)

RE: Studies on the Ring revolution frequency | |
Bonjour,
Pouvez vous enregistrer les images de l'oscilloscope et le donnée brute à la place des screenshots. Il y a une option dans l'interface web pour enregistrer l'oscillogramme "proprement". De même pour les images, cela permet de faire des traitements à posteriori.
Merci.

9:15 Mise en chauffe modulateur
10:23 Temperature chiller incorrecte
11h Optilization of the beam for injection. Beam is unstable, what is seen fro, the x/y position trends in the TL. Then, from time to time the beam is not injected in the ring causing the jumps in the signal intensity ???
12h Hayg helped to find the good conditions and we started to inject in the ring but still with the not stable beam.
14h We try to store the beam by optimizing the parameters of the RF cavity => approaching the good storage. Suddenly the beam changed the parameters and we lost injection.
16h Trying to reestablish the injection and perform the optimization AGAIN
17h Difficult to restore the storage: beam from injector is not stable and therefore difficult to see the effect from the ring studies
18h After several studies, we found the proper RF frequency for current ring settings 500.4259 MHz
With ~20 kV obtained storage is about 15 ms measured with the additional electrode on the scope. Libera several times went down and had to be restarted.
The injection is not stable (intensity goes from 0 to max value), which makes it VERY DIFFICULT to optimize the beam storage in the ring. We added two QUAD (4 and 5) to our optimization routine.
After orbit correction the storage was 100 ms with ~20 kV RF and fRF = 500.404 MHz
Studies to be continued. More stable beam is requested from the injector.
19h30 Shift is finished.

15h Scan extraction kicker vs EL/BPM.01.
See attached plots.
Some interferences with ring storage.
Stay around -8us.
Testing reproductibility
Extraction timing=-8.088
Transmission 9%
16h40 Scanning EL/PS/DP.01...
Transmission 36% but it is not clear if the improvment comes from the ring or the transport.
Storage losses in the ring are about 50% so less than 15% losses due to ring injection+extraction.

11h50 Modulateur en chauffe
Pb aimants.
12h20 Cyclage dipoles en cours
13h : Faisceau
13h15 modulateur tombé (redemarrer sans pb)
scan charge-phase => charge Max : 360
Charge energy max : 320
13h45 : modulateur tombé
14h00 Mesures intensité sur les caméras en fonction du retard (point 3 du programme)
17h Jitter sur faisceau en fin de linac et apres dipole
Claquages observés sur les cameras
L'énergie du faisceau est trsè basse (courant dipole à 154 A pour voir le faisceau sur TL/SST .02
18h05 : fin du run
===
Programme pour le faisceau 15/9
*** Accès casemate
1) alignement Cerenkov + retournement des caméras (Démarrage machine à 10h30 au plus tard).
*** Faisceau linac
2) Observation Cerenkov jusqu'à 12h
*** Faisceau LI+TL+EL
3) Mesure intensité vs retard sur chacune des stations SST LI+TL+EL
4) Injection anneau
5) Balayage en temps du Septum. Observation de l'effet sur RI-C1/DG/BPM.02 et BPM.03
6) Balayage en tension du Septum. Observation de l'effet sur RI-C1/DG/BPM.02 et BPM.03
7) Balayage en temps du Kicker. Observation de l'effet sur RI-C1/DG/BPM.03
8) Balayage en tension du Kicker. Observation de l'effet sur RI-C1/DG/BPM.03
9)Try to use TL/PS/STR.04 V+H to try to optimise the trajectory in the ring (I will use the QP values that were saved tonight).
10) Adjust RI-C1/PS/DP to center the beam in the BPMs
11) Use steerers before each BPM to try to center the beam in that BPM. See how far we can go like this...
