Start chauffage 9H

There were some problems: the phase section motor was in the wrong position, although the readings were normal; The rear door of the septum power supply was not fully closed.

12h04 Beam is in the ring, RF cav. at 50 kV, phase is 22.5 dg., the receipt from 17/04/2025 12:31 for the ring.  RF gun phase is 153.6 dg. Sect Att. is 2.74 dB, Sect. phase is 211 dg. Receipt saved to referenses folder with MSRV mark

** Recherche point image camera MRSV

Deplacement vertical camera par pas d'environ 5 mm  - Mesures des fwhm X et Y camera

12h15 Modulator has been put into standby mode: access to the bunker.
12h45 HV is 'ON' RF gun phase was set to 143.6 dg. Sect phase was set to 208 dg. Charges: -41 pC, -41 pC, -45 pC, Ring TbTsum about 2e7
13h55 Modulator has been put into standby mode: access to the bunker.
14h13 HV is 'ON'
14h16 Modulator has been put into standby mode: access to the bunker.
14h29 HV is 'ON'
14h35 Modulator has been put into standby mode: access to the bunker.
14h49 HV is 'ON'
15h00 Modulator has been put into standby mode: access to the bunker.
15h15 HV is 'ON'
15h22 Modulator has been put into standby mode: access to the bunker.
15h38 HV is 'ON'  RF Gun phase is 144.6 dg.
15h46 Modulator has been put into standby mode: access to the bunker.
16h06 HV is 'ON'
16h27 Modulator has been put into standby mode: access to the bunker.
16h46 HV is 'ON'

==> cf screenshot des trends fwhm X et Y MRSV
       Points notes sur brouillon par Daniele, a fitter avec une parabole pour determiner les 2 minima X et Y (astigmatie)
       Data des trends : MRSV_fwhm_X.dat et MRSV_fwhm_Y.dat dans data/shared

** Verification avec le laser des axes X et Y pour voir s'ils ne sont pas inverses

16h52 Modulator has been put into standby mode: access to the bunker.

Les axes X et Y MRSV sont bien les axes reels X et Y
Cf screenshots : total_beam, coupe_moitie_basse, coupe_moitie_haute

** Test de la procedure de calibration de la cam MRSV

17h28 HV is 'ON'

Position verticale faisceaux sur les 2 bpm autour du dipole :
     1) nominal MRSV  
     2) +0.8
     3) +1
     4) retour nominal MRSV
==>  La positon verticale sur MRSV varie bien comme on l'attend
        C'est reproductible  ==>
Calibration a faire avec la camera en position image
