7h50: mise en chauffe en remote (chiller, frigo, laser, modulateur) Demarrage alignement sur l'axe du CdTe pour prendre un spectre 70 MeV 12h20 HV is 'Off', Stop RF to go to bunker - SHUTTER ligne X en defaut - Essai de resoudre le probleme, sans succes - Appel Harold 13h20 HV is 'On' Investigation on the X-rays Several vertical scans In the single trigger mode the vertical scans give sigma ~70-80 um while in the normal mode (10 Hz injection) the scan is very wide. The results are in agreement with the shape of the beam on MRSV. Should be understood. The storage is good at 70 MeV 18h10 End of the shift

9h30 : mise en chauffe intervention casemate pour alignement laser et nettoyage optique. 11h : démarrage, charge énergie max 100pC pour atténuateur à 330pas, phase 187° On charge la recette et on règle le linac (energie et phase); position TL/BPM.02 à 0, et min de dispersion (tout allumé) 11h34 : stockage immédiat dans l'anneau ! C'est TOP ! Après midi compliqué pour trouver les rayons-X et avoir un cavité stable. synchronisation X : * delay 33MHz/Trig ~ 2-4ns * phase 500MHz CFP: 6.45V prise de spectres X : * déplacement du faisceau de rayonx X (à gauche et en bas) du à la nouvelle orbite * spectro déréglé + trop de flux (saturation de l'acquisition) Mise en place d'un "asservisement" du pointé d'injection dans l'anneau. Semble bien fonctionner (cf. screenshot), meme avec des variations d energie etc. Script dans : data/shared/commissioning_scripts/Linac/Alignements 18h30 : Stop ThomX * Programme prochain * * trend de flux avec asservissement du pointé d'injection * affinement de la position du 0 du faisceau X * mesure spectre angulaire * prise d'une image du faisceau de rayons X

9h: mise en chauffe (Klystron, refroidissement, laser) ==> problème Vide (vide8) ==> Problème phase shifter Laser PC (on redémarre le boîtier) ==> la synchro saute à cause des phases : on réajuste le rigole +10° : Phase voie 1 : 120° Phase voie 2 : 265° 13h15: intelock vide 8 17h15: arrete machine, acces casemate pour la CFP ** Programme - Mise en place du MRSV (vision caméra) 11h le MRSV est en place avec un premier alignement à tester en faisceau. - Mesure de l'influence sur les sautes de l'alignement Laser/cathode, de la charge, et alignement Linac 12h: Alignement1 on charge la recette good_20241009_17_38_49 - Quads (courant nominal QP1, QP2, QP3) : -0.08 A, 3.4 A, -3.4 A - section non tunée - charge ~ 100pC LI/STR1 : [H,V] = [2.16,-1.7] LI/STR2 : [H,V] = [-3.83, 2.20] ==> cf. data Alignement1: saute de 1.4mm en Y et 0.6mm en X en 30min 13h: Alignement2 On règle la section (dispersion min, et énergie tel qu'à 159.3 on soit au centre du BPM/TL2) ==> cf. data Alignement2: saute de 1.2mm en Y et 0.7mm en X en 30min 13h45 charge 50pC ==> cf. data Alignement3: saute de 0.6mm en Y et 0.7mm en X en 30min réajustement phase canon EmaX et att + phase section 14h52 charge 120pC ==> cf. data Alignement4: saute de 0.6mm en Y et 0.7mm en X en 30min les sautes cotes linac TL/BPM01 sont visibles mais très atténuées sur TL/BPM02 (quad 4=0) 15h40 test action steerer tl1 sur BPM TL1 et 2 (saut de 600µm sur avec steerer 15h42 sur BPM1 et à 15h43 le saut de 600µm est bump) saut sterrer visible sur BPM2 pas le bump!!! TEST 1 on prend un trend de la position du faisceau sur YAG TL01 en parrallèle avec TL/BPM01 ==> les sautes sont visible sur l'écran: 0.8mm/10pixels TEST 2 on fait des jumps de la pos laser sur la cathod de 0.1mm (saut 16h30 bump 16h31) ==> déplacement legerement visible sur TL/BPM2, ratio BPM1/BPM2 (0.5mm/0.05mm) TEST 3 on fait des jumps sur les steerers LI V 1 et 2 (+- .1A à V1 16h41 V2 16h43) ==> saute visible sur les 2 BPM ratio BPM1/BPM2 STR1 : 0.5mm/1mm et STR2: 0.8mm/0.5mm** TEST pompe : on arrete les 2 pompes ioniques LI/VA/PP.05 et LI/VA/PP.06 à 16h58, on les remet à 17h10 ==> difficilement quantifiable, il reste des sautes. ==> Conclusion sur les différents tests : * Les sautes ne sont pas visible sur TL/BPM.02 mais visible sur TL/SST1 * Ce n'est pas un artéfacte de mesures de TL/BPM.01 * Il semblerait qu'il y ai un plan image du TL/BPM2 * Le plan image serait autour de LI/STR.02 ou de la cathode. ==> un déplacement laser ? - Mesure performance alignements : Quad courrants initials, Quad courrants nuls, section ?

8h15 : démarrage de la chauffe (Frigo, Modulateur, laser) Problème avec le login operateur (lent) et client1 freeze ==> redémarrage ~9h30 Access to the casemate to fix laser photodiode The laser energy is 50 uJ ~10h00 Charge-phase scan Phase Laser gun 130 ~10h30 Injection in the ring. The full optimization should be done giben the change in the injection phase RF section 116 deg. (was 89) Good transport until the ring and good stability during the day. 12:00 Oscillations betatron observees dans l'anneau avec la cavite tunee and a bit of power ~100 W (see pictures) Looking to improve number of turns in the cavity... Not possible to store the beam for more than ~10-20 turns. La cavite a un effet en X (voir image ADC BPM) We tried to measure the revolution frequency with the BPM connected to the scope. With the first analysis it is ~30*Frev = 499.87 MHz. To be checked. Several phase and freaquency scans with RF cavity. Usually working at 5-7 kW. 19h Machine stopped

8h15: Mise en chauffe du modulateur et des chillers. Défaut Laser à investiguer pour la mise en route ("flow interlock") 9h: démarrage Laser PC (problème de niveau d'eau résolu) 9h19: Defaut sur RI-C2/QP2 a 6% du cyclage 9h20 Pression 2,5bars, bouteille retiree. Phase section: 229. Attenuation: 2.56dB en venant de 2.7dB (Attention, au backlash) Apparement, il y a un backlash d'environ 0.1dB sur l'attenuateur. 10h08 Modulateur passe a OFF soudainement, status bit 8 Faisceu redemarre Pour les quad RI-C2/QP2: Cyclage etait a 9A, cyclage limite a 7.5A. Cela devrait fonctionner. En cyclant les dipoles de l'anneau on ameliore le transport dans la EL... Mettre RI-C1/QP.01 a 250A. Bruit sur EL/BPM.01, electrode B: Apparement le bruit viens du cable jaume branche en C3 sur le chassis du libera 01 Le faisceau sur EL/SST.01 est coupe si EL/DPI.01 est supérieur à -7.40A Recette sauvee pour transport jusqu'a EL/SST.01: TL_good_20240926_14_21_58 Problème de synchro qui saute : * Le problème semble venir de la CPLD (cf. Screenshot_2024-09-26T13-25-29), courbe jaune = sortie trigger box pour RING, bleue = sortie trigger box pour modulateur * Le modulateur semble bien etre à 50Hz, en revanche les autres trig (anneau) ne sont pas à 10Hz comme demandé * la phase des signaux (rigole ou laser) ont un influence sur le comportement. * Changement du MCT2E mais le problème de commutation sur le signal 50Hz en sortie persiste (cf. Screenshot_2024-09-26T14-38-19), courbe bleue = sortie du MCT2E ==> peut etre le transistor avant ou un défaut de masse ?. - Le problème semble lié à cette commutation visible sur les signaux en sortie de trigger box (cf. Screenshot_2024-09-26T14-49-02) - test effectués : -- changement des niveaux des signaux (Laser et 33MHz), -- changement des phases (Laser et 33MHz), -- reboot de la carte CPLD, -- changement des codes fréquences, -- mise en test d'une résistance sur la "bobine 50Hz" en entrée de trigger box * Le problème n'est pas présent quand la machine est à l'arrêt. Un équipement vient perturber les signaux. (cf. Screenshot_2024-09-27T05-41-07), une fois la machine éteinte. ==> Il faut investiguer la source de bruit et/ou s'en affranchir (mise en place d'un filtre) Etude retard EL/DG/SST.01 17h58: Arret

Mise en chauffe Modulateur vers 9h 9h - 10h : installation Laser 33MHz de la CFP par Ronic Vers 10h Ronic informe qu'un des câble d'alimentation du boîtiers interlock du 1e dipôle de la CFP a été arraché par maladresse. Le fil a été re-soudé et attaché au bundle de câble. Impossible de passer en TRIG ==> le PA est disjoncté ==> le MPS bloque le PA parce que les dipôles anneau sont en erreur. Après acquitement tout est OK Faisceau à 11h. Marie à refait les mesures d'alignement Quad. Prise de donnée pour alignement automatique du laser sur la PhotoCathode Prise de donnée pour alignement automatique dans les Quad (pseudo correction d'orbite) ==> les BPM saturent, les caméras sature losrque le faisceau est focalisé. ==> Les données sont peut être à jeter. Arrêt machine 17h15 * OBSERVATIONS * Lors des tests, nous avons trouvé un nouveau point d'alignement laser sur la photoCathode (5.0xx, 3.22). Les caractérisitques de ce point par rapport au point habituel : - en dehors de la zone du courant d'obscurité. A la position du repique dans le scan phase-charge - Insensible à la variation de phase à charge max - Charge plus important (200pC au lieu de 150pC) - Le faisceau est plus déformé (cf. image en PJ)

10h : mise en chauffe de la machine (chillers, modulateur, laser, alims). * Programme * - Stockage des e- et puissance laser * Stockage dans l'anneau immédiat avec la recette (ajustement linac : phase et attenuateur, pres) * Problème avec la cavité RF, phase étrange (faisceau tué après quelque us) ==> il faut aller loin dans le scan de phase * injection réajusté par Iryna * Cavité locké à 8kW - synchronisation CFP sur horloge machine (une fois les rayons-X trouvés/observés en mode désynchro) * rayons-X trouvé (4pA dans le détecteur fluo) * essaye de synchronisation (rebranchement du cable 33MHz CFP) ==> pas assez de signal ==> ajout d'un ampli dans la synchroBOX - scan du buket RF (scan déphaseur 500MHz CFP avec compensation déphaseur 33MHz CFP) * Impossoble de faire des scans : pas assez de stabilité (juste pour retrouver la phase RF avec la cavité - scan des numéros de bucket * changement du programme CPLD (une basule) pour ne pas etre synchrone avec le 33MHz (33x33 ==> 41MHz) ==> on ne trouve rien également le changement du bucket RF n'est pas assez régulier. Mais on dégrossis la phase 500MHz (environ 7V sur le dephaseur 500MHZ CFP) * Remise du programme CPLD précédent : (33x33 ==> 33x41 ==> 41MHz avec ligne à retard externe) * scan du bucket RF avec le géné 33MHz (24° à 33MHz = 360° à 500MHz) ==> ca marche et c'est répétable il faut pour cela : ** mesurer la phase entre le 33MHz CFP et le trig (pour avoir le bucket RF) 1) Locker la cavité CFP sur le 500MHz 2) "mesurer" le bucket accroché (aujourd'hui, trig pris dans l'igloo et le 33MHz CFP en sorti de déphaseur 0V de consigne) 3) déphaser le géné pour retrouver le bucket RF correct (équivalent à 26.5ns de delai entre le trig et le 33MHz CFP), la phase de référence sur le géné était de 53.5° recommencer à chaque délock de la cavité. ==> on gagne un facteur 100 au niveau du flux. A affiner, il manque un facteur 10 qui peut venir de : jitter synchro ou CFP ? La puissance laser et la charge stockée sont pris en compte au niveau du signal de référence en non synchronisé (3-4 pA), on doit avec la synchro avoir un facteur 1000 environ. 17h35 : arret machine

Redémarrage ThomX : * remise en pression d'eau sur la boucle principale (légèrement inférieur à 4bars à l'arret). * PSS HS (écran freezé) ==> rémarrage de l'écran de l'automate (nécessite la clé de l'armoire) * mise en chauffe du modulateur (9h) Programme journée : * essaie d'alignement automatique (laser photoCathode + quad) * génération d'une recette pour injection dans l'anneau (mesure émittance + énergie) * Tests correction orbite TL ********* * L'alignement automatique du laser sur la PhotoCathode semble fonctionner mais est très bruité dû au bruit sur les BPM (~1mm en X) De plus il y a une saturation sur les BPM (LI et TL/BPM.01 au moins), cf. Screenshot ==> cela doit destabiliser l'alignement automatique. * Alignement Steerer VS QP, même constat que pour la photocathode. Le bruit des BPM limite la résolution de l'algorithme * Mesure Alignement QP de la TL ==> manque données BPM pour TL/BPM.04 (mean, std des positions)
