## Integration Department Organization

## Run Coordinator’s Responsibilities

- Create and coordinate the operational planning for the accelerator complex
- Run daily Integration Meeting to discuss and formulate the operational plan
- Coordinates studies and commissioning activities
- SY120, Recycler, NuMI in FY2005
- Shares responsibility for handling unusual operational situations
- Develops and oversees operational guidelines for the Operations Department
- Evaluates and oversees operational policies of Systems Departments
- Monitors peak operating performance of the accelerators
- Receives and coordinates requests from the experiments

## How does the Run Coordinator’s job differ from before?

- Operational planning and coordination now the primary focus
- Long range planning, weekly and monthly presentations are handled by Department Head
- Creation of integration team reduces the burden on the Run Coordinator
- Uses input from other groups within the Integration Department in decision making
- Shot analysis, evaluating studies requests etc. is now a group effort
- Run Coordinator is no longer a 4-month term
- Provide long-term continuity for operational goals, strategy and monitoring
- Part of the work load is shifted to other members of the Integration Department

## Organizational Strategy

- The Operations Department will assume more responsibility of the day-to-day running of the Collider and the external beamlines
- Larger reliance on Crew Chief decision making (as in the latter part of Run 1)
- Can handle large percentage of decisions based on guidelines from the Run Coordinator
- Improve communication between Run Coordinator and experiments
- Experiments participate in daily Integration Meeting
- Use Run Coordinator elog to disseminate information related to the accelerator plans and status
- The experiments are the customers of the Accelerator Division

## Run Coordinator Electronic Log Entry

- Studiers: J. Morgan
- Start of Studies Notes:  Record store 3245 continues in the Tevatron. We are building up the Recycler stack.
- The Recycler will be delivering the next set of transfers to the Tevatron, hopefully tomorrow.

- _[  ](http://www-bd.fnal.gov/cgi-mach/machlog.pl?nb=runco&action=xe&page=68&time=10:17:51)_   10:17:51-  Notes from the 0900 Integration meeting: Linac reports that the I- cleaning has been completed and are reasonably confident that the debris they found was the source of the sparking problems. They hope to begin running the source next week and will find out for sure. Booster did some parasitic collimator moves yesterday, they would like about 2 hours of dedicated time for collimator studies. There should be time this afternoon. Main Injector is running fine. They will work with pbar to find out if we are ready to start making 2.5MHz coalescing operational for the pbars. This would make coalescing efficiency less dependant on the longitudinal emittance coming from pbar. The Tevatron had end of store studies and did separator scans. The vertical angle scan across B0 required a manual polarity change of the A17 separator. Although the luminosity didn't improve as expected, losses appeared to be lower. They would like to repeat the scans. There is a study they would like to do at the beginning of a store, 2-4 hours of lifetime vs. collision helix amplitude. The next store from the Recycler appears to be a good choice. They would also like about an hour at the end of the store to do studies with the synch light mirror. The Recycler has had good efficiencies on their pbar transfers, they have also been training other people on the process. They plan to use momentum mining on the pbar transfers to the Tev. The next Collider transfer will come from the Recycler. SY120 appears to be ready to begin running operationally at ...

## Shot Strategy

- Long duration stores and large pbar stacks
- Minimize effects of shot setup and associated delays
- Large stacks allow extracting a smaller fraction of the pbar stack, leaving more for the next transfer
- Reduce inefficiency of experiments due to turning on to begin a store and turning off at the end
- Minimize the impact of studies and stacking downtime

## Summary

- Changes to the position of Run Coordinator
- Run Coordinator is no longer a 4-month term position
- Run Coordinator is now a member of the Integration Department and can focus on operational planning
- The Operators, and especially the Crew Chief’s, play a more prominent role in decision making
- Emphasize communication and collaborative planning with the experiments
- Operational strategy
- Try to run long stores and shoot from large stacks
- Schedule accelerator studies and commissioning in such a way as to minimize the impact on integrated luminosity
