1 PPC 9/10/98 G.Cyvoct PS/OP Start up: grâce au travail de préparation (Linac et PSB) durant aôut et septembre, nous avons obtenu un faisceau de 1.8 e10 charges (acc.) en 2 heures. Limitations actuelles: - intensité (22 A) du Linac3 - qualité du vide: ring PSB Pb ions beam in the PSB Update: 8/10/1998
