Salut Steen,

Pour répondre à tes questions :

a. oui c'est possible de réinstaller le modulateur,

b. il est prévu pendant le ls2 de modifier le switching de la Grid et du Contrôle. J'ai déjà reçu les nouveaux modules et on doit faire un nouveau proto. L'idée est de faire un switching rapide et ainsi d'activer les BPMs avec le faisceau d’électrons. Si ça marche on pourra annuler l'étape a) A bientôt Alex
