Technical Progress


Scope Changes Since Last PMGScope Changes Since Last PMG

• Modified: 1.1.2 (Quad power supplies)

• Significantly reduced in scope• Keep original supplies and upgrade controls electronics• $1M+ -> ~$200K

1.2.1 (Determine rep rate limits)• Modified to include RF reliability concerns

1.3.4 (MI RF Upgrade)• Significantly reduced in scope• (more in a bit)

• Added: 1.2.12 (Booster RF Improvements)

• Systematic plan (based on 1.2.1) to refurbish Booster RF modulators

• Descoped: 1.2.6 (Booster alignment)

• Decided to treat as part of normal operations 1.2.8 (Cavity 20)

• Manpower limitations. Limited success of cavity 19


ProgressProgress

• Baseline plan Aim for a director’s baseline review 7/21 B. Baller will give more details

• Technical ProgressLinac 1.01.01 PA Vulnerability –

• Committee report completeBooster 1.02.01 Determine rep. rate limit

• Good understanding of what limits repetition rate and reliability

• Generating report• Suggesting a plan of action (1.02.12)

1.02.02 Orbump (+ 400 MeV line) – • New injection scheme passed review!• Three magnets built• Beamline and girder design more or less complete• Power supply passed review• Will be ready for shutdown


ProgressProgress

Booster 1.02.03 Correctors –

• Design nearly complete• See C. Drennan’s talk

1.02.05 Gamma-t system• Ongoing studies look encouraging• Made decision to scrap existing magnets when we install

the new correctors• If system is useful, will build (12) new magnets between

now and then) 1.02.11 Booster Dump Relocation

• Review going on in WH12NW as we speak, HOWEVER• Considering rather significant change to kicker location• Will be ready for shutdown

1.02.12 Booster RF Improvements• NEW SCOPE• Significant refurbishment plan for Booster modulators• Waiting for recommendations of 1.02.01


ProgressProgress

Main Injector 1.03.01 Large Aperture Quads –

• On track for shutdown 1.03.02 Collimation –

• MI-8 Collimator design complete and reviewed• Will go in in shutdown• Working on conceptual MI ring collimation

1.03.03 NuMI MultiBatch Operations – • Regularly deliver 5 batches at (Total 2.1E13 protons)

to NuMI target• Aim to start slipstacking earlier than anticipated

1.03.04 RF Upgrade – • Discussed shortly

Studies 1.05 Proton Study Group–

• Preliminary report delivered to PAC on recycler retasking

• Overall report delayed by some more grandiose proposals than we anticipated.

• Hope to have a final report by 8/1


Main Injector RF (1.03.04)Main Injector RF (1.03.04)

• Great progress has been made in understanding the limitations of the existing feed forward system. Calculations Beam studies

• News is good The preliminary result is that the capacity of the RF system

is >5.5E13 protons with no significant RF upgrade

• Working on specifications for going to 6E13 in the most conservative scenario (i.e. upgrade some fraction of cavities to 2 PA’s)

• This will free up a significant amount of money for other activities (e.g. Booster RF modulator refurbishment)

• Prototype tests proceed, but have been delayed due to badly overcommitted RF group


Near Term PrioritiesNear Term Priorities

• Prepare for shutdown!!! 400 MeV Line+ORBUMP Booster dump relocation MI large aperture quads

• Prepare for baseline review Working on Design Handbook Settling on scope of baseline (B. Baller’s talk)
