  1. It is not a Project! Muon Acceleration ProgramTechnology Development A. Bross NFMCC CM January 15, 2010 A. Bross NFMCC CM January 15, 2009

  2. MAP - Technology Development A. Bross NFMCC CM January 15, 2009

  3. Technology DevelopmentLevel 2 Task A. Bross NFMCC CM January 15, 2009

  4. Normal Conducting RF • Y’All know the Drill: • Three Approaches • Reduce/eliminate field emission in Vacuum RF • Material Studies • Process cavities utilizing SCRF techniques • RF cavities filled with HP gas • Utilize Paschen effect to stop breakdown • Magnetic Insulation in Vacuum RF • Eliminate magnetic focusing • Not Yet Tested • This is an area where there is already great pressure to down-select • “Resistance is Futile” • But we must, at least initially A.

  5. RF Milestones A. Bross NFMCC CM January 15, 2009

  6. Super Conducting RF • You we hear about this in detail from Don next • But: • Need lots of 201 MHz • But, use 500 MHz as test vehicle • Application of ALD A. Bross NFMCC CM January 15, 2009

  7. Magnets • Other than the Very-Large-Magnetic volume needed for the NF TASD concept, all magnet work for MC/MCDFS • HTS solenoid R&D to assess the parameters that are likely to be achieved • HCC magnet R&D to assess the feasibility of this type of cooling channel and possibly to build a demonstration magnet for an HCC test section (see Section 6.2.2) • Note: Success with the HCC could make it cooling choice for NF also. • Open mid-plane dipole magnet R&D to assess the viability of this magnet type for the collider ring • Very fast ramping normal-conducting magnets for the later stages of acceleration • This may turn out to be an indispensible cost-saving technology • Other magnet studies to inform choices, parameters and cost estimates for the target-station solenoid and accelerator magnets.

  8. Milestones A. Bross NFMCC CM January 15, 2009

  9. Targetry • Targetry is not currently explicitly in the text of the MAP proposal under Technology Development, but under the ISD-NF • With the input from the MERIT experiment, the U.S. contribution to the IDS-NF in this area will be on more advanced simulations to set definitive benchmarks for the NF/MC target system • Make the next iteration on the facility design (following the ORNL/TM-2001/124 technical report) and to develop engineering details of component parts of the system such as the target solenoid • But from Kirk’s (Harold’s) talk yesterday, we see that there is room for optimization • Splash mitigation in the mercury beam dump. • Possible drain of mercury out upstream end of magnets. • Downstream beam window. • Water-cooled tungsten-carbide shield of superconducting magnets. • HTS fabrication of the superconducting magnets. • Improved nozzle for delivery of Hg jet • -------- A.

  10. Overall Goals A. Bross NFMCC CM January 15, 2009

  11. Global Manpower Effort - FTE This is a sum over all types: Scientists, Engineers, Postdocs and Technicians A. Bross NFMCC CM January 15, 2009

  12. Overall Effort & Likely available Resources • With current guidance we are not likely going to be able to do even all the tasks we currently have on our “A” list • Getting convergence on the overall Program Plan will take some work over the next weeks. A. Bross NFMCC CM January 15, 2009
