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 |
7h55: mise en chauffe en remote (modulateur, cyclage, laser, frigo/chillers)
==> plus de trig sur la machine (sur toute la plage de scan de la phase stab du laser PC). ==> OK, je suis une truffe le laser était "off"
**** Programme ****
- mesures RP
- test de différentes position IP pour remédier aux spectres en "dromadaires"

Planning de la semaine
Lundi
9h- 11h :
activité cavité Fabry Perrot
Mise en place du disque dur alimentations 10h - 13h
mise en place de la mesure de phase en salle laser
Vérification des valeurs prises dans l'archivage (charge à 10 Hz, BPM sortie canon, phase)
Lundi après midi : suivi de la mesure à paramètre constant (phase à la max de charge, visualisation écran, charge, mesure salle laser)
Mardi/mercredi : poursuite du suivie la mesure (Hayg et Marie et Marc(le mercredi))
Jeudi : journée dédiée activité Fabry Perrot
Vendredi : journée test matériels BPM charge (Vincent, Alexandre, Nicolas)
------------------------------------------------------------------
Résumé des discussions
Pour le problème de la phase :
1. Mise en place de la mesure en salle laser (Vincent + Viktor)
2. mettre en place un ordinateur windows en salle de contrôle
3. Prévoir un ordi de pret, ou une mise en place remote desktop pour la semaiene prochaine
4. Vérifier en parallèles des mesures en salle laser la charge, BPM, et phase à 10 Hz : avec l'archivage + visualisation en salle de contrôle
5. Intervention pour la mise en place du coup de poing dans la casemate le jeudi 10 février. Planifier si on effectue dans la foulée un test qui necessiterait l'arret des matériels en amont
6. Problème de commutateur de la baie réseau de la casemate soulevée par Ronic, ainsi que de cablage non prévue
8. Besoin d'un temps pour changer le boitier cpci pour le pilotage des alim.

Following:
1) a crash on 4th of April and a violent reboot of the ELLiOOs embeded machine
2) the need to recover the whole database files in the ELLiOOs embeded machine
the ElliOOs sofware was running back quickly. Though recently (in terms of working and available days) was reported that the tango DS was not communicating.
The reason why stayed misterious.
Following calls to Amplitude Laser (Vianney) last week and, today, a callabck from SCARELL (Romain and Jean-François), it is now understood that :
- the content of the data repository corresponding to the Tango gateway was not dynamically created (~/bin/ElliOOs/User/Data/28*/*). The specific file that was missing since the 5th of arpil reeboot was Plugin.sml.
Recovering this file and properly rebooting the embedded machine (from the ElliOOs programme running on the HOST, in the System Info --> reboot embedded), allowed to revoer the com.
Indeed it was checked by looking at jive by Falcoz.
An archive of the Code repository was done in case it is required to recover these files again. Archive sent to SCARELL.
Please remember to reboot the embeded in case there is a reoboot of TANGO machine in the main control room or if the database is reset.
Please also note that trying to look at the content of the TANGO_HOST variable in superuser or default user will not help in understanding if tango is running locally.

9h14 Mise en chauffe
Pas de camera laser qui s'ouvre sur PlateformeIHM
9h19 cyclage aimants LI, TL sur interface
soucis DS camera laser, impossible à redémarrer.
--> du coup impossible de démarrer le feedback du laser
Chargement recette good_20241114_15_27_46, optimized storage for X_rays (5/6)
Mesure energie : 48.34 MeV attenutation 2.7 dB
Energie = 54.21 MeV attenuation 1.7 dB
Energie = 58.77 MeV attenuation 1 dB
Energie = 60.29 MeV attenuation 0.5 dB
Passage à 61.5 MeV dans la TL --> recette enregistrée
Passage à 70 MeV dans la TL --> recette enregistrée, solenoide est à 210 A, dipole = 255.8A
Modification des steerers :
LI/PS/STR.01_H01 = 1.17A
LI/PS/STR.01_v01 = -2.16
LI/PS/STR.02_V01 = 2.32
LI/PS/STR.02_H01 = 1.17A
Images sauvegardées le long du transport
Après alignement quad sans le steerer TL :
LI/PS/STR.01_H01 = 1.18
LI/PS/STR.01_V01 = -220
LI/PS/STR.02_H01 = -2.97
LI/PS/STR.02_V01 = 2.34
Puis mesure transmission charge vs soleno
