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

6. Super Conducting RF  You we hear about this in detail from Don next  But: u Need lots of 201 MHz u But, use 500 MHz as test vehicle u Application of ALD A. Bross NFMCC CM January 15, 20096

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) u 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 u 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.

9. Targetry  Targetry is not currently explicitly in the text of the MAP proposal under Technology Development, but under the ISD- NF u 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 u 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 s 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.
