7h40: mise en chauffe en remote (frigo/chillers, modulateur, laser, cyclage)

 

*** Programme ***

- repartir de la recette "iniale" de jeudi avec un grand angle vertical à l'IP

- trouver le point de "bascule" horizontal de l'IP avec la CFP (point immobile en fonction de la phase CFP)

- Changer l'angle vertical pour trouver le minimum acceptable pour les spectres (par dicotomie)
