2) Inject in the ring
3) Save ring recipe
4) Check BPMs in AGC mode
5) Check screens calibration
6) Changement mesure taille SST |

Beam is stored | |
Shift started at 18h
With the current injector settings, it was difficult to inject. We loaded the settings from last Friday 30/09 (19-22-04).
Principal steps:
- Correction of the one quadrupole polarity this morning
-injection tuning, observation of Turn-by-Turn-X, Turn-by-Turn-Y and Sum
-quads focusing, defocusing +-.0.5%
-iterative manual adjustments of corrctors, DPI, Septum, Kicker
-orbit correction with open line model response matrix
- several datasets taken for further postprocessing
Beam is stored !!!!! ~400 turns (limited by the Libera response)
Stored beam, visible more than 300 turns, signal decay as estimated due to Libera cutoff filters. To store more, RF cavity should be used.
Stable closed orbit!
Important milestone is achieved.
No losses at scintillator/fiber except for the injection, see oscilloscope screenshot.
Current machine settings are stored in recipe_recipe_LI_TL_RI_20221003_20_24_01.txt
Orbit is stable for more than one hour. End of the shift.

BPM LINAC + TL : dispersion tir a tir ? | |
Aujourd'hui Iriya m'a montre en salle de controle une "etendue" de ~4mm de l'orbite du faisceau mesuree sur le premier bpm de l'injection (celui appele bpm 2 je crois) sur une vingtaine de tirs. Ca semblait pareil pour 500 tirs, i.e. ~4 mm). C'est beaucoup ... (Iryna peut-etre pourrais-tu mettre ce que tu m'as montre dans le elog ?)
--> Ce que je suggere de faire des que possible (vu avec Hayg) : un script permettant de mesurer cette etendue de l'orbite tir a tir sur les 5 BPM LINAC + TL, pour voir si cette dispersion est presente qq part avant, ou bien si elle est creee seulement au niveau de l'injection.
Bonne soiree |

Goal: Ring BBA
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

10h20 HV is 'ON'
RF Gun phase is 254 dg. Sect phase is 243 dg. Sect. Att. 0.119 dB, Charges: -112 pC, -113. pC, -140 pC. Linac steeres: H [1.00 -3.49], V[1.92 2.13]
11h00 Beam is in the ring. Receipt 70 MeV from references BPM TL2 X=-1 mm
11h30 HV went standby. Maher fixed it.
11h32 HV is 'ON'
BPM transmission does not work properly (see screenshot)
Good storage at 70 MeV with the receipt.
Laser phase adjustment during the shift a few times
Work on the BBA at 70 MeV
For this, measurement of the ORM. There is a differennce with the model ORM. Attempts to tune the ring from the model. Work should be continued.
Due to this, only manual BBA can be done at the moment.
Starting also to adress the manual BBA in the TL. We used HCOR2 and QP5 and TL BPM.03. The results are not clear (big element-to-element distances). To be continued.
18h STOP THOMX

Attenuateur LIL / Puissance LIL / Energie electrons | |
La puissance entree canon a ete verifie et conforme a l'atterndu (6 MW = 18/3 MW)
Avec l'attenuateur a 2 db, le power meter dans la casemate affiche 9 mW entree LIL.
--> Le faisceau est detecte sur BPMTL2 et sur YAGTL2 pour I_DIPOLE = 143 A ce qui, avec les caracteristique du dipole, correspond a une energie sortie section de 45.5 MeV |
