  19. Planning with Accelerator Users and Maintenance Staff • 8:00 Meeting every day, seven days a week, in MCC. • Operations report by EOIC, including run time statistics, progress in carrying out scheduled program, descriptions of problems, etc. • Reports by representatives of major experimental user groups. • Attended by PPA, Accel Div, and Operations management reps, Program Deputy, System Physicists, Area Managers, and representatives of user groups and major technical support departments; typical attendance: 45 persons. • 8:15 Maintenance Meeting, five days each week. • Run by Accelerator Operations Department maintenance managers. • Attended by supervisors of all maintenance groups, Area Managers, and interested physicists and engineers. • Attendance: typically 45 persons. • Accelerator Plans Meeting, weekly. • Review of operational progress, problems, and plans. • Attended by Accel Systems Div and Dept Heads, Program Coordinators, Accelerator Section Heads and ADSO. • Upgrade planning meetings held several times a month. • Accelerator Improvement project • Equipment projects FY09 Linac Ops Review Page 19

  20. Accelerator Maintenance and Upgrades • Planned Maintenance Days • Whenever possible, identified maintenance, repair, and installation jobs are pre-planned. • Coordination • Daily 8:15am meeting. • Coordinated by Operations Maintenance Office. • Area Managers are advocates for their areas. • Standby Maintenance List (SML) • Jobs that are planned and can be launched on short notice. • Provides options for EOIC to take advantage of unscheduled interruptions. • CATER Electronic Database records items. FY09 Linac Ops Review Page 20

  21. CATER Maintenance Planning and Control • CATER database accessible over the internet by everyone involved with SLAC accelerator maintenance. • Operators report problems as they occur by making entries in CATER. • Repair work is launched immediately if the problem is inhibiting the scheduled accelerator program. • Jobs are tracked using CATER until they are finally closed. • CATER entries since Jan 1989: ~86000. • CATER entries in one year (2006): • New problems (~20 per day). • Problems closed (~20 per day). FY09 Linac Ops Review Page 21

  22. Long Down Time Planning • Long Down Times usually occur once each year and typically last two to three months. • Area Managers collect job requests from system physicists, project engineers, maintenance groups, and the ARTEMIS database. • A comprehensive schedule is prepared, updated, and reviewed at weekly meetings, starting about four months before the down time. • This schedule lists each job with an assigned shop, and lists the Project or Group Manager, Responsible Task Person, and Area Manager. • Schedule specifies time and duration of each job (with 1 day time resolution), and number of persons required. • Schedule specifies authorizations required (WAF, RSWCF, EWP, etc.). • Detailed (shift by shift) schedule of pre-run testing, safety certifications, and turn-on activities is prepared by the Operations Dept and revised as needed on a real-time basis.

  27. Legacy and Risk Items • Legacy items: • Linac Variable Voltage Sources (VVS) for klystrons are original equipment. Fortunately, very few have failed. Plan in place to slowly replace them. (Risk ~1 week down) • K10 substations are original equipment and are slowly being replaced. (Risk ~1 week down) • High voltage linac power cables for substations are slowly being replaced. (Risk ~1 week down) • Linac control system (20 year old SLC era) is being maintained and is slowing being replaced. (Risk ~1 day down) • Risk items: • All components have gone through safety assessments and have mitigations including fire, earthquake, electrical, pressure vessel, … FY09 Linac Ops Review Page 27
