## Proton Plan Status January

- Eric Prebys

## Agenda

- Operations  – Prebys
- Technical Status/Shutdown Preparations – Prebys
- Cost/Schedule Report – Baller
- Shutdown Teaser – Bob Mau

## Operations

## Operational Highlights

- Excellent performance for NuMI and PBar beam
- With the exception of a leaky NuMI magnet
- Very good efficiencies for cogged cycles
- Too bad MiniBooNE isn’t here to enjoy it!

## Energy Loss on NuMI cycles

- Protons/batch

- Energy Loss (J/E12)

## NuMI

- Dotted lines are 2.4 second rep rate

## MiniBooNE

- What can I say?

## Total Booster Output 

- Mostly reflects loss of MiniBooNE

## Technical Status

## Significant Activity Since Last PMG

- (1.1) Linac
- (1.2.2) Quad Power Supply Upgrade
- All P8 cards replaced
- Three prototype P1 cards in service
- Being evaluated
- Ready for procurement
- Design of three others complete
- Waiting fir results of P1 test
- (1.2.4) Linac LLRF Upgrade
- Passed design review
- Beginning to set up test system
- Affected by delay of ILC FPGA module
- Will use prototype board for test system
- Will still be in during shutdown IF the ILC prototype works reasonably well
- Also affects MI RF project
- Also, will need time in the near future to adjust coupling of station 3 or 5
- Involves moving coax line
- ~1 shift to do + 1 shift to tune

## Booster Activity

- (1.2) Booster
- (1.2.3) New Corrector System (Lots of progress!!)
- Magnets
- Cores arriving from vendor ahead of schedule
- Look good!!
- Coils behind schedule
- Potting fixture had to be rebuilt
- Becoming worrisome
- Curing oven could be bottleneck
- Will know more next week
- Power supplies and cabling
- 40A Ready for procurement
- 60A Nearly ready for procurement
- Cable ordered
- Due March 31st
- Controls
- Moving ahead

## Booster (cont’d)

- (1.2.13) Booster RF Reliability Improvements
- Hoped to have a full cost and schedule estimate for water upgrade by this PMG
- Mike May identified required modification to manifold system for modulator water distribution.
- Working in scope change.

## Main Injector Activity

- (1.3) Main Injector
- (1.3.2) MI Collimation Systems
- MI-8:
- Now used operationally
- Ring:
- Drawings complete (for collimators)
- Should go out next week
- Working on bus rerouting scheme

## Main Injector (cont’d)

- (1.3.3) Multi-batch slip stacking
- Lot’s of progress in 11 batch slip stacking (see following slides)
- (1.3.4) MI RF
- On track, but tight
- Affected by delay of ILC LLRF FPGA module
- Considering back up plan using prototype boards

**Current operation**

**Multi batch**
**Slip stacking**

**11 batches**

**7 batches**

- Fit MI ramp to 2.2 sec
- Verify 11 batch slip stacking scheme
- Send 11 batch to Numi target with int. of ~3.0E13

## Status

- Records:
- 11 Batch (MI) Record:
- 3.7E13 to MI dump
- 90% efficiency
- No reason we can’t send this to NuMI (will try today)
- NuMI record
- 3.5E13
- 85% efficiency
- Issues:
- Dampers don’t work because of the multiple frequencies during slip stacking
- Damper group working on two board solution
- Approaching limits of MI RF system
- Will need collimation to run operationally

## Shutdown Preparations

- See Bob’s talk for details
- Beginning to make concrete plans
- Coordinator: Rich Andrews
- Floor Manager: Fernanda Garcia (backups: Todd Sullivan and Jim Lackey)
- Individual bosses assigned.
- Will begin to meet with AMG in the very near future
- Complication:
- MTA beamline will be a significant project competing for resources and Fernanda’s time
- Date?
- June off table
- July possible, but tight
- More comfortable with August 1
