- Valeurs du jour : betaX = 30.4 betaY = 81.6 alphaX = -6.5 alphaY = -8.5
A suivre - Trouver Bonne figure of merit + minimisation emittance ....
2) Valeurs QUADs "QP3" utilisee dans la simu RING (quads autour de l'IP) :
QP3 SIMU julien : - 6.7 A
QP3 REEL :
c1_qp8 = -6.02
c2_qp8 = -6.03
c1_qp9 = -6.11
c2_qp9 = -6.0
==> ~ 0.7 A de difference - Pour les autres quads : SIMU vs REEL sont proches.

Preparation/check of the 70 MeV WP for X-ray run | |
Goal: preparation and checking the machine operation at 70 MeV and 40 MeV (ideally with X-rays)
8h54 Warming up
RF section 29.20 C -> 28.5 C
9h45 Beam on
Start at 50 MeV and then going to 70 MeV with 70MeV_Xrays_I3I4_20kpA_flatVertorbit_vertSigma_122um__20250821_14_36_08.txt
In this recette the dipoles are at 253.78 A which is 2A lower than nominal current for 70 MeV. The goal is to go to the nominal value.
Phase scans, beam is transported to the ring. Only few turns.
Scan of he RF cavity phase.
scope 192.168.229.22 which used to monitor losses and charge is not accesible as someone else is connected to it from srv 3 with 192.168.229.92. We need control of this scope in the CR.
After also checking it locally, the signals were not set, cable unplugged.
12h30 Problem with SST. Nicolas is checking.
Optimization of the injection. HCOR/VCOR are set to zero. Storage obtained; RF ON freq 500.031690 MHz
Several interlocks shutter laser linac
13h20 Stop for the visit
14h47 beam on
Daniele worked all the afternoon with the students. FPC is changed for 70 MeV.
MRSV does not start; need help for it
Work on the 70 MeV. orbit is corrected. The final tutning should be checked with X rays.
At the end we understood thqt the EL dip is set to 159.3 A. The orbit was recorrected with only the EL dip set to 253.8 A (the difference in the orbits is shown in the scrennshot). The rest of the elements of the EL are should be scaled to 70 Mev (it will not impact the orbit as dipole)
The recetter is saved:
70MeV_ELdip253p8A_20251204_18_10_12.txt
70MeV_with ELat50MeV_20251204_17_10_20.txt
The BLM signals during the shift were moving in time: to be understood, maybe timing problem.
This configuration must be checked with MRSV and/or X-rays to confirm the X-ray flux |

shift du 27 novembre 2025 | |
8h: mise en chauffe à distance (modulateur, frigo/chiller, laser, cyclage)
9h30: Chargement de la recette : "recipe_recipe_LI_TL_RI_all_20251126_09_35_14.txt" pour référence
ajustement energie linac et phase cavité RF pour réduire l'oscillation synchrotron.
10h43: prise de référence, dispersion -3cm
10h50: recette dispersion Viktor V1, dispersion -7.3cm
10h55: recette dispersion Viktor V2, dispersion +10.3cm
11h: essaie recette Julien, pas de charge transmise sur ict3. Faisceau très défocalisé et ligne trop fermée (très sensible aux petites variations pointé, énergie etc.)
11h30: essaie recette référence avec feedback injection ring
11h50: recette dispersion Viktor V3, dispersion -9.5cm
12h: effet stockage sur faisceau,
1) le faisceau est stocké avec la recette de référence, optimisé avec la phase cavité RF et l'energie ==> faible oscillation synchrotron mais stockage instable (grosses pertes en fin de stockage)
2) le faisceau est optimisé pour augmenté la qualité du stockage. Faible jitter d'injection et stockage stable (sans perte) mais grosses oscillations synchrotron
Les deux mesures de longueur de paquet montre qu'un mauvais stockage peut permettre d'avoir un meilleur faisceau en longitidinale alors qu'un bon stockage peu vite dégrader le faisceau. QUESTION: est ce uniquement en lien avec l'oscillation synchrotron ? Est ce que le fait que le faisceau soit vite dégradé améliore la stabilité du stockage ?
===> Au final il ne semble pas y avoir un fort impact sur les jitters en fonction des différents points de dispersion. Le point à 11h30, est le point de référence refait avec le feedback d'injection anneau, il semble moins bon.
Sur l'image le point marque la valeur moyenne et la barre d'erreur l'écart type des 100 mesures (jitter), pour BPM.02-LIB.03 (BPM1) et BPM.04-LIB.03 (BPM3)
*** Mesures faites pour chaque points ***
- mean / std, de 100 acquisitions des positions BPM X et Y (des 12 BPM de l'anneau) pour le numéro buffer (0, 14, 100, 500, 1000, 1999)
- Archivage mesure le stockage et autre donnée
- image de l'orbite en comparaison avec la référence
- image oscillations synchrotron
- image TBTsum
*** Programme ***
Injection stability en fonction de la dispersion 100 pC :
Quantify injector stability vs. TL dispersion
Goal: Understand and minimize the shot-to-shot jitter at ring injection by tuning TL dispersion.
Workflow:
Vary dispersion in the TL in a controlled way (use > 5 optics settings).
For each dispersion setting:
- Measure horizontal and vertical jitter in the ring (turn-by-turn).
- Record injected charge, storage efficiency and orbit offset at injection.
Try to match TL dispersion to ring dispersion at injection and identify the setting that minimizes jitter.
Summarise the best TL dispersion setting and assign it as standard optics.
Deliverables:
Jitter vs. TL dispersion curves.
TL optics for minimum jitter.
Beam time: ~2 shifts.
*** après midi ***
- problème RI-C1 QP.05, problème : electrodes désoudées ==> ressoudées avec Jean-Noel.
- immersion recherche : quelques images de radiofraphie (portable, carte banquaire, baume à lèvre) ==> cavité extrèmement instable !

17h: changement solénoïde 180 --> 230A, on a un peu de charge transmise (70pC pour 100pC). +1A sur QP5 afin d'avoir un faisceau focalisé sur TL/BPM.03. Injection faible possible mais très sensible à la sortie linac (après 2 min plus de charge transmise ==> ligne trop fermée)

** Mesures longeur de paquet et injection
- Comparaison en fonction de la qualité du stockage:
* mesure de la longueur pour l'anneau non optimisé (après dérive), il y a des oscillations synchrotrons (~4mm pic-pic), le stockage est pas stable
* mesure de la longueur une fois l'anneau réoptimisé (énergie + 3° cavité RF)
- Comparaison taille faisceau VS amplitude cavité RF
==> pas d'effet visible du FBL (il faut peut être l'ajuster)

09h14 Unable to start thomx. Need help. Probably problem with cooling water.
12h35 Warm-up the modulator, Chillers started
12h42 Cycling all magnets
12h57 It seems that leds at LI/SST1 and TL/SST1 are ON. . Fix. IHM ==>'Camera Power'==> 'Power 3'
13h42 HV is ON
14h06 Strange situation: the modulator works, but there are no radio frequency signals (see the screenshot).
15h46 Maher fix it. HV is ON
16h16 the modulator works, but there are no radio frequency signals
Need help from Maher to restart the pre-ampli.
16h34 Up to now, the beam was transported only till TL/SST.02. Very often we observed interlock (something happen in the IGLOO ?). After this probably the pre-ampli stopped operating. This is our observation. Moreover, several mistriggers.
For the RF cavity, there is the problem to set the Voltage. It can be done only manually by Mohamed.
The control of the iris thouth the ELLO com4 does not work. It says "COM4 not available".
Shift program even has not started.
16h54 STOP

7h50: mise en chauffe en remote de la machine (laser, frigo/chiller, cyclage)
==> le modulateur ne répond pas aux commandes (il est peut être en local) ==> Ok le modulateur était bien en local (Maher est intervenu)
*** intervention laser (9h 11h) ***
* Pas de perte particulière sur la ligne observée, le faisceau ne semblait pas non plus avec une forme dégradée.
* nettoyage des optiques dans la salle laser, ajustement du téléscope de la casemate (pas d'effet notable mise à part une perte d'intensité sur la caméra sans perte de puissance côté canon)
** Mesure Laser PC **

15h34 HV is ON
Tests on Ring + Streak camera to measure the bunch length. Triggering was not perfect (many jumps, even with help from Daniele)
Laser charge is now lowered (max around 300 pC) , should be realign soon.

08h34 Warm-up ThomX: Modulator, Laser, Fridge
08h40 Chillers were started, cycling all magnets
09h40 HV is ON but cannot trig because the interlock on low SF6 pressure. Assistance asked.
10h40 Modulator set to standby, because nobody responded.
SF6 pressure was fixed.
14h00 Beam started. The laser iris was set to 2 mm because at 1.3 mm beam was with two cores at the linac exit.
Receipt used: all_20251106_13_58_04
RF gun phase 233 dg. Sect. phase 211 dg., Motor position of the sect. Att. about 1700 steps to get 50 MeV. Charges (BPMs): -110 pC, -110 pC, -113 pC, -113 pC. Do not use calc/li/hfi/att.01-mot.01 to adjust section RF power in dB, use li/hfi/att.01-mot.01 instead. Level of a signal from the section output should be about -0.125 V at 50 MeV.
14h16 Beam is in the ring, RF 100 kV. TL/BPM02 X=-1mm.
BBA for a vertical direction.
BPM V [1 1] V offset = -0.054 mm
BPM V [1 6] V offset = 0.165 mm
BPM V [1 7] V offset = 0.025 mm
BPM V [1 12] V offset = 0.366 mm

08h30 Warm-up ThomX: Modulator, Laser, Fridge
08h36 Chillers were started, cycling all magnets
09h33 HV is ON
09h34 HV set to 1215 V RF Gun phase is 188 dg.
11h09 Help needed! Something is wrong with the TL bends.
11h44 Something is wrong with the section attenuator. Reducing the attenuation results in a decrease in the section's output power.
12h15 OK, finally we got it. RF Gun phase 182 dg. Sect. phase 298 dg. Sect. Att. 0.59 dB, 50 MeV, Li/HFI/ATT.01-MOT.01 ==> 311 steps Sect. Output -0.123 V
Sect. Output -0.123 V Mot. pos. 1699 steps but Sect phase = 211 dg. Calc/Li/HFI/ATT.01-MOT.01 is not working properly.
