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 |

run du 20 avril 2023 |

Suite du run du 19 avril : objectif mesure des twiss pour plusieurs valeur de solénoides à partir de 180A
NB : Problématique de dérive des paramètres rencontrés entre le temps de réglage, et le temps d'acquisition --> mesures non traitables
NB2 : dimensions sur TLSST1 en fonction du solenoide différent de l'autre point de fonctionnement (lien évident entre l'alignement de la machine et les twiss ...)
Alignement quad par Kevin
scan sur TLSST1 en fonction du solénoide avec le script matlab
- 180A 104°/2.03dB, image prise sur TLSST2 QP123 [-2 +3.9 -1.1]A, Idip 159.3A
quad scan QP3 à 180A [-1.81 2.23], puis [-1.72 2.15]A, les conditions ont bougées sur TLSST2 entre deux mesures...
- 200A, 4 quad scan QP3 [ -2.35 2 D] A ; [-2,95 2,35 D] A ; [4.1 -3,9 D] A ; quad scan QP1 : [ D 3,76 -3,86] A
- 220A [D 3,18 -3,58]A
phase réajustée à 93degrés pour Idip =157.9 A, TLSST2 enregistrée [1,37 3,18 -3,58]
Difficile de savoir ce qu'on fait avec tant de paramètres qui bougent

shift du 12 février 2025 - Alignements | |
8h: mise en chauffe à distance (modulateur, frigo, chiller, laser)
9h30: laser semble pas aligné dans l'iris avec une forme assez étrange (trou au centre) ==> énergie sortie laser PC 270uJ
9h35: la forme du laser sur la photocathode virtuelle semble etre revenu avec l'alignement M5.
10h: démarrage des alignements Quad et Photocathode.
Nouveau point Cathode : [H,V] = [4.46, 3.46]
--> Réglage 50MeV, min dispersion
** Mesure alignement vertical QP1-3, QP4-5 :
QP1-3 : TL/BPM.01 [x,y] = [-0.09,0]mm ; TL/YAG.01 [x,y] = [395, 265] pixels
QP4-5 : TL/BPM.01 [x,y] = [-0.1, 0.22]mm ; TL/YAG.01 [x,y] = [395, 263] pixels
On trouve faisceau dans QP4-5 "descendant" par rapport à QP1-3 (mauvais sens par rapport à la section) ==> impossible d'aligner QP1-3 sur la section sans désaligner QP4-5.
Delta entre axe QP1-3 et axes QP4-5 = 0.2 mrad (vertical)
** Mesure section alignee (strLi du elog 1002)
Axe section : TL/BPM.01 [x,y] = [-2.6,3.7]mm ; TL/YAG.01 [x,y] = [250, 67] pixels
Delta entre axe QP1-3 et axes section = 1.2mrad (vertical) ==> non cohérent avec les mesures précedentes (elog 1002)
==> elog 1002 du 22 janvier : il y a certainement eu une erreur de lecture de mesure du bpmTL1 pour l'axe section
Les autres mesures sont coherentes entre aujourd'hui et le 22 janvier (bpmLI, YagTL)
Plusieurs prises de mesures axes SECTION et Q1Q3 avec les valeurs de steerers suivantes :
- align section : cf. elog 1002 du 22 janvier
- align Q1-Q3 strLI H1 = 0.83
V1 = -3.26
H2 = -2.89
V2 = 3.50
==> Cf. reconstruction en screenshot
rouge : axe section
bleu : axe Q1-Q3 avec Q1, Q2 et Q3 OFF
vert : axe Q1-Q3 avec Q1, Q2 et Q3 ON
==> quand on reconstruit les axes verticaux QP1-3, QP4-5 et section on trouve les defauts suivant :
- section - QP1-3 : 1mrad (sans calib BPM), 0.5mrad (avec calib BPM : X = valeurBPM / 0.8)
- QP4-5 - QP1-3 : - 0.2mrad
==> les désalignement verticaux semble très faible (<1mrad), mais il y a un gros "shift" de l'axe section.

Shift du 2 février 2024 | |
La clé PA est resté enclenchée hier. Il faut penser à la tourner avant de partir (demande de Maher)
8h15 : Mise en chauffe machine (aimants, chillers, laser, modulateur).
Pas de mesure de charge (WAC, délai ?)
Recherche de la cause de la perte de puissance
** Klystron 1090 ==> 2MW en Pi Load
Initial : TL/BPM.02 à 0 (Dipôle 160.8A) ==> 1.27dB
On test les sources de pertes de puissance :
* Changement frequence RF (-500Hz)
pas de changement
* Changement temperature section ( consigne 29.5°C ==> 29.2°C)
TL/BPM.02 à 0 ==> 1.39dB
On continue pour trouver l'optimum
optimum trouvé autour de 27.0°C en consigne.
TL/BPM.02 à 0 ==> 1.73dB
** Essaie de rentrer dans l'anneau. Impossible de faire un tour. Reprise du septum, on gagne 2 BPM mais les deux dernier ne voit pas de faisceau.
==> problème de délai des EP ?
Hier modification du retard du laser PC pour vérifier que l'on était bien dans l'impulsion RF au niveau de la section LIL. Passage du retard de -8.2µ à -8.4µs (pas de changement sur l'energie faisceau)
remise du retard à -8.2µs
parametre pour mardi
recette good for Xray and EL opérationel (atténuateur section 1.385dB 29.2°C)

Emittance measurements at 70 MeV
15h10 Set to 50 MeV; Gun Phase is 154 dg., Sect. Att. is 2.62 dB; Receipt from 28/11/2024 17h51
16h10 : loaded good storage for x rays from recepies to check 50 MeV . From this setting lets check back alignment in quads from the quand alignment script.
Before alignment : AL1
Str01-H01 : 2.69
Str01-V01 : -2.14
Str01-H02 : -4.46

Str01-H01 : 2.89
Str01-V01 : -1.92
Str01-H02 : -4.44
Str01-V02 : 2.33
But : transmission (charge) : drop by 40%
Let's do soléno scan to check transmission : Quand alignment not very good for charge transmission, see attched plots.
Let's check alignment on the section for the 2 alignments. We change the section phase by 50° and see displacement (Yag and BPM). For this, Quads should be off.

some tries to enter the ring, by using same recipe than last friday. But someting changed, not possible to get back to the same storage. May be beam quality has changed from last run.
--> We need to find a set of observables to be checked to get back to the same beam quality for injection !

Test of the new receipt from BMAD Isol = 242 A | |
8h55: mise en chauffe (modulateur, frigo/chillers, laser, cyclage)
10h20 HV ON
Start with the receipt nominal. problem with the RF gun laser camera. Solved.
Going to the new receipt for Isol = 242 A
Tuning injection. Good storage.
We performed sveral scans with FPC. The measured vert beam siwe is about 82 um. The best X-ray fluc I3+I4 was about 30-40 kpA.
The size at MRSv hor/vert is about 15/19 pixels
Starting from a certain moment, the trig to trig injection stability changed. See the screenshot. This to be understood.
Going to nominal receipt. After the tuning of the injection, the good storage is obtained. Size at MRSV 15/24 pixels
measurements of the dispersion and LOCO studies. First without sextupoles and later with. To be continued.
Going back to new receipt Isol = 242 A. Storage is bad. Retuning of the TL and injeciton. Good storage is obtained with good tunes 0.17/0.7.
Studies with X-rays will be continued tomorrow.
dispersion and beta function measurement as tunes are seems to be quite stable
Switching on the streak camera.
Phases during the day:
RF Gun: 296; 229; 242
RF section: 218; 209; 218

Soucis machine : 
- Redpytaya : impossible de les démarrer

Peut-etre soucis au niveau du trig du Laser, si qq peut nous aider ... 
c'est un pB soft...
redpitaya 2 3 4 baie 17 redémarées (serveur en carafe)
