Magnet control upgrade
Wk 49: nous devons intervenir dans la MCR pour: changement des alimentations 24V et 48 V des systèmes MSS et MCR (préventif) changement des modules convertisseurs PT100 des hots points du Solénoïde (correctif suite à deux incidents ayant entrainés l'arrêt du Solénoïde) et en UX25, comme Philippe Bouvier l'a déjà signalé: recâblage des AU du dipôle et du Solénoïde signalisation du champ magnétique du dipôle et du Solénoïde Nous étudions toujours une solution pour le monitoring des températures du Solénoïde. L'arrêt de fin d'année va permettre de faire une meilleure approche de ce qui est existant en UX25. En ce qui concerne l'alimentation électrique de la MCR, nous dépendons actuellement d'une seule source de courant sous UPS avec secours diesel. Afin d'établir une redondance pour l'alimentation de la MCR je souhaiterais installer une seconde source d'alimentation sous UPS. Je sais qu'une étude est faite à ALICE pour augmenter la puissance des UPS existants en 2012. Je souhaiterais que cette demande soit incluse pour le calcul de puissance des nouveaux UPS (besoin pour la MCR: 16A en monophasé) 21/1/11 ALICE planning meeting Pascal
