  1. Proton Improvement PlanBill PellicoApril 19, 2013NOvA collaborationMeeting Bill Pellico NOvA

  2. PIP Work Update • Injector (RFQ) • RFQ injector installed • Nov FY13 • Operations Dec FY13 • Hardware/ Beam Studies Continue • Linac • Beam established Nov FY13 • Beam physics – matching • Match to RFQ injector • Working on lattice/software • New BPM/Toroid electronics • Upgraded vacuum systems • Booster • New beam absorber • 19,000 lbs of steel & concrete for dump of notched beam • 3 kicker systems configured • Solid State Completed • New Modulators • New Power Amplifiers (PA) • New Solid State drivers • Controls and Cabling • Magnet/orbit Corrections • Beam physics - Lattice Corrections • Upgraded LCW system • Refurbishment of RF Cavities • 6 of 19 completed Bill Pellico NOvA

  3. Beam Status • RFQ injector largely in operations mode • Still adjusting new sources • Beam current at ~ 30ma but design is for 35ma • Second Source – with some improved hardware/design being tested • Additional trim package being added in May - should help increase beam current • Linac Commissioning continues • Efficiency improved with new injector • Still lower current then before shutdown – but improving • Before MI starts ups – will have to work on two week stations (saving tubes) • Booster beam up and running • Beam at half of desired (pre-shutdown) levels • Work on RF systems (Refurbishment) limits beam current due to lower voltage • New orbits/operating point being studied • Still working on RF systems – commissioning – debugging • Refurbishment continues and will require stations out of the tunnel for repair – two more years • Beam shielding assessment still being worked on – should not prevent operations Bill Pellico NOvA

  4. Booster RF Upgrade(s) • Solid State, Cavity Refurbishment, Alignment, LCW systems, New cabling, Passive Damper Work Booster Cavity Work Refurbished (15Hz) SS Prototype SS Upgraded Cavity Removed Bill Pellico NOvA

  5. Solid State PA Booster Notch Beam Absorber Booster Aperture Scan Booster Solid State RF Station Bill Pellico NOvA

  6. Near Term Plans • RFQ injector – Will be adding a new trim package (improve transmission) • Installing Booster Utility Transformers • Installing Linac Roof access • Booster Magnet Moves continue • Booster Cogging studies • Booster Lattice Studies • Booster Cavity Refurbishment • Operations: • Higher Intensity Tune-up • Address shielding assessment issues to allow for higher flux Bill Pellico NOvA

  7. PIP - issues • Beam operational goals vs. Refurbishment • Having station(s) out of the tunnel will be a vulnerability • Get done faster or perhaps more downtime • Labor • Need people to work on RF • Skilled work that takes training • Low dose rates – but long hours creates radiological issues • Funding • Big items just getting started • Klystrons for low energy linac • New Booster Cavity • New Booster Tuners • Need to adjust to changing laboratory priorities/funding Bill Pellico NOvA

  8. Proton Source/PIP – FY13 Calendar High Intensity Tuning Booster Linac Beam Studies Cogging Magnet/Aperture Moves Injector Tune-up Dampers Lattice studies/corrections NTF RFQ MI Startup Bill Pellico NOvA

  9. Proton Source Throughput Goals (Base lined timetable/goals FY12) NOvA Shutdown LBNE 120 GeV Mu2e g-2 8 GeV

  10. We are currently on a ~ 10weeks/cavity • Labor • Use contract help • Lots of training • Labor intensive job • Radiation • Low doses – but long jobs Bill Pellico NOvA

  11. PIP Gant (Using FY13 Estimates) Completion Date Base Lined PIP Removed Required for 12 Hz Required for flux Required for 15 Hz Required for reliability FY13 Q1 Milestones and Goals look good Q2 through Q4 start to see budget impacts on some base lined milestones. Bill Pellico NOvA

  12. PIP Support • We set up a model for participation • We put together a spreadsheet of potential jobs • The jobs are organized in areas of scientific, technical, and machining • We had a meeting for all spokespersons to discuss • The request went out for help from all the experiments • We had four volunteer institutions from MicroBooNE - none from elsewhere (Therefore they will get the best Protons!) • We are in the process of putting out a first machining job • Other jobs are in the process of being screened • Keep talking to directorate – defend labor and funding Bill Pellico NOvA
