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

==> 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
