  1. 真空状况(5月14日8:00-15日8:00)李生发(白天)王小明(晚)真空状况(5月14日8:00-15日8:00)李生发(白天)王小明(晚) 1, 全天内衬烘烤电流50A, 15:00内衬烘烤电流降到30A 2, 全天感应烘烤,电流125A 3, 10:00内衬221 0C, 限制器1800C, 15:00内衬2220C, 限制器1830C. 4, C段顶部装PV-10阀拟充氖. 5, 15:20 停水平道SX 能谱抽气机组. 停气动探针抽气机组,探针与主真空室阀门打开,检漏OK. 6, 21:50 3台低温泵开始再生;停感应烘烤和内衬烘烤;关真空 采集和保护系统;关所有分子泵机组阀门,停泵。 7, 22:15 供电维修,停电! 8, 22:40 来电!测内真空室静态真空为1.3 E-3Pa,外真空室为 2.0E-3Pa 启动所有分子泵机组,正常后开阀门 内衬烘烤电流30A;感应烘烤电流123A

  2. 10,23:00 低温系统供冷, 回路氦压力较高(1.5MPa),外真空室真空变坏, 气压短时间升至1.8E-1Pa,10多分钟真空后恢复到E-3Pa水平 11, 3:30 3台低温泵停烘烤, 5:00 启动低温泵 12, 7:35, 开东低温泵阀门(3.3E-7Pa)和西低温泵阀门(4.3E-7Pa) 13, 7:00 内衬160 0C, 限制器1030C,
