git pull sur $HOME_IHM


pression vanne vide : 8 bar
resistivité eau : 7.3 Mohm


Health_check :
Jauge dans l'anneau en erreur : -> verifier quel jauge a été supprimer est les enlever de la verification d'état
RI-C2/PS/STR.02-V.01 :

  • En ALARM
  • Status :
     port 1 configured as -- no information --  
    SIGMAPHI-6 REMOTE OPERATION 
    Alimentation Port 1 DC OFF 
    Alimentation Port 1 SOFTWARE INTERLOCK 

LI/OP/OPT.02-LAS.01-OSL.01:

  • Etat : FAULT
  • Status : OK
    Est il pertinant de la conserver dans Health_Check et/ou de considéré que le "state" FAULT revoie une erreur "FAULT" ?

Moteur miroir laser en gris (state inconnu) :

  • State : MOVING
    -> ajout de l'état "MOVING" de gravité "OK" dans les fichier de config Health_Check

Pas de soucis empechant le démarrage de la machine !

Nicolas H and Alex L from SOLEIL came to participate in the shift.

Nicolas H configured phase_offset for all Libera to reduce the jutter in the TbtSum signal. After this, the signal became more stable.

Nicolas H, VC, VM and IC measured the jutter of the BPM wrt the injection trigger. it was found that the jitter is 12 ns !!!!! Then, it was also confirmed by measuring the jitter on the scitillator detector signal. This is a big problem, which should be considered/solved asap.

With the help of Alex L, the good transport is done until the last BPM of the Ring (see file attached). The task now is to try to futher correct the trajectory for the second turn. From the vertical orbit we suspect that dipoles could be missaligned at the IP region. To be checked if it is compatibe with the simulations.

Discussion on the allignment of the Ring should be organized to get the last measurement results and understand, what can be done in terms of the correction of the dipole tilts/shifts if it will be needed.

The example of the one possible trajectory is attached.

With the scintillator detector installed near the septum, we see the beginning of the second turn (see file attached). It is useful diagnostics as the BPM will give the evidence of the 3rd turn only (Libera averages the signal from 2 turns).

19h20 Tuning of the trajectory. More or less flat stable trajectory. Work is ongoing.

21h50  End of the shift
