Laser camera does not work. Help!!!

MRSV camera too!!!

The cemeras and laser are working now. But we do not see the laser beam. Daniele checked the laser spot in the casemat. Apparently it is cut. Help is needed with the laser!

During another attempt to launch laser position feedback, the diaphragm completely disappeared outside the screen (to the right).

OK it was fixed

09h57 beam is in the ring w/o RF, recipe_recipe_LI_TL_RI_good_20260318_16_17_14.txt loaded. Laser phase 5 dg. (to low), sect. att. 0.148 dB, sect. phase 258 dg., Charges around -100 pC,

10h06 RF 100 kV, phase -45 dg.

10h30 interlocks even at sect. att. 0244 dB

11h15 Sect. temp. set to 29.2C  (Clarinette, Consigne 28.6 C)

11h57 laser phase jumped to 18 dg.

12h25 For the 70 MeV settings (DP current 255.8 A) the linac energy is too low, so we left 253.8 A ==> 69.7 MeV.

18h10 ThomX was stopped

8h: mise en chauffe en remote (frigo/chillers, laser, modulateur, cyclage)

*** Programme : Mesure spectre et monochromateur à 61.5MeV (70MeV si le temps le permet)

61.5 MeV

09h35 HV is on
photocathod laser phase 62 dg.  The receipt 61p5MeV_20250703_12_56_55.txt loaded, going to 61.5 MeV (interlocks)
10h13 Beam is on TL/SST02. Sect. att. 0.992 dB, sect. phase 236 dg.
10h30 Aligned with QP1 - QP3, linac steerers: H [-0.2 -3.02], V [-2.55 3.22]
11h05 Beam is in the ring W/O RF with all ring correctors set to zero

RF 100 kV storage is good, but can't correct the orbit  at 61.5 MeV :  le faisceau est presque hors du tube ==> Try to go to 70 MeV

70 MeV

13h20 RF processing the section on 25 pps by increasing pulse length from 1 us to 3 us
13h56 70 MeV, Linac steerers H [0.21 -3.75], V [-2.84 3.33], sect. att 0.18, phase 255 dg. laser phase 56 dg. (On the base of 70_MeV_Vert_tune 0.66_good_20251212_13_56_38.txt)
16h17 recipe_recipe_LI_TL_RI_good_20260318_16_17_14.txt saved, screenshots, RF 100 kV, phase -36 dg., Freq. 500.031645 MHz

L'orbite n'est pas la meme que pour 50 MeV  ==> Checks spectres dromadaires a V+40 

X_fpc = -1.5 / -1.3 / -1.7 / -1.9 / -1.1  mais on a oublie d'ajuster la phase a chaque fois  .... meme phase (3.0 V) 
X_fpc = -0.9 / -0.7 / -0.4 / -0.2 / -0.5  en ajustant la phase a chaque fois
Cf les 2 screenshots "Spectre 70 MeV"

On se place a X_fpc = -1 mm (pas top mais dans l'urgence on se met la)

Fente2 centrees a l'oeil : [H , V] = [11 , -23]
Prise de spectres a +/- 10 en H et V  (a voir ce que ca donne offline)

17h56 ThomX was stopped
