- Presentation of Proton Plan Baseline - Sims
- Cost/Schedule Report – Sims

## Operations Report

## Operational Issues (NuMI)

- Implemented interleaved “NuMI only” cycles into standard operation
- Discussed at last PMG
- Have gone from 5->6 NuMI batches on NuMI only cycles
- ~5 batches at 2 second rep. rate, as in plan
- Significant improvement in beam loss on high intensity cogged cycles
- Demonstrated 5E12 booster batches to NuMI
- Just before target problems
- Bottom line:
- NuMI is pretty much at their goal, until slip stacking (some time after shutdown)

## Operational Issues (MiniBooNE)

- Working with operations to formalize Booster tuning procedure to maximize and regularize Booster total output.
- Agreed on MiniBooNE beam monitoring procedure
- i.e. when to call control room
- Increase MiniBooNE batch size
- First time extended period >5E12 protons/batch

## Total Energy Loss Improvement

- Batch Size

- Normalized Energy Loss (kJ/E12)

- Cogged Cycles (NuMI/Stack)

- Uncogged Cycles (MB)

- 5E12

- 5E12

- Batch Size

- 9/9/05

- Now

## FY05 Final (Total Beam)

- 3.75E20*

- *Total protons in 30 years prior to MB turn on ~5E20

## FY05 (NuMI)

- Caught up from target problems!

- .67E20

## FY05 (MiniBooNE)

- 2.6E20

## Projections for FY06

- NuMI
- Design
- Gradual increase in batch intensity to ~constant 5E12
- Begin to implement slip stacking of 1 year following next shutdown
- Base
- Run like we are not
- MiniBooNE
- Design
- “Design” proton capacity projections from Proton Plan document.
- NuMI at design.
- Base
- “Fallback proton capacity projections from Proton Plan
- NuMI at Base
- Shutdown
- Assume beam off for full 14 weeks starting Feb. 6
- Conservative, not entirely consistent with Plan
- Projections go up if injector complex stays up.

## NuMI Projections

- Too close?

## MiniBooNE Projections

## Total Protons

## Technical Progress

## General Comments

- Shutdown date still not final
- We can easily move the shutdown tasks themselves to accommodate new shutdown.
- Have not taken into account the affect of the lower priority resulting from delayed shutdown
- Schedule will show huge float
- It will look like we’re falling behind
- Not worth chasing a moving target.

## Shutdown Preparation

- In general, we are in very good shape for the shutdown.
- Nevertheless, these are big jobs that require a lot of coordination
- We’ve appointed Rich Andrews “Shutdown Coordinator” for the Proton Plan
- Primarily an oversight position.
- Job will be to communicate with Level 2 and 3 managers, as well as support departments to identify problems and help to solve them.

## Progress

- Technical Progress
- Linac
- 1.01.01 PA Vulnerability –
- First 2 of 12 new tubes scheduled to be delivered this month.
- 1.01.02 Quad Power Supplies
- First of seven replacement cards designed
- Starting on second
- 1.01.04 LLRF Upgrade
- Working out performance benefit in an effort to increase priority.
- Booster
- 1.02.01 Determine rep. rate limit
- 1.02.02 Orbump (+ 400 MeV line) –
- Finally settled on “no shim” design
- 5 magnets complete except for endplates and insulators
- First two ready for testing in 1 to 2 weeks
- Girder back from vendor
- 400 MeV design complete
- World’s most detailed ALARA under way.

## Progress

- Booster
- 1.02.03 Correctors –
- Design nearing completion for prototype
- Working out test and QA procedure
- Final specs will go to EE support within a week or two
- Broken into two installations
- Long (verticals) in 2007
- Short (horizontals) in 2008
- 1.02.11 Booster Dump Relocation
- Delay caused by need move PS location in Booster West Tower
- Largest single project in the shutdown
- Still in good shape
- Working to reconcile our labor estimates with Dave Augustine.
- 1.02.13 Booster RF/ Rep. rate Improvements
- 15 Hz transformers have been given increased priority in purchasing to have them ready for installation it the shutdown.

## Progress

- Main Injector
- 1.03.01 Large Aperture Quads –
- Planning to install all 7 during shutdown
- 1.03.02 Collimation –
- MI-8 Design being finalized
- Long lead times ordered
- Will go in in shutdown
- Working on conceptual MI ring collimation
- 1.03.03 NuMI MultiBatch Operations –
- Regularly deliver 5 or 6 batches Total (>2.8E13)protons to NuMI target
- Doing prep work to do in tunnel improvements to MI-10 kicker to allow for slip stack operations after shutdown.
- Added badly needed RF expertise for MI modeling (Tim Barenc)
