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 initially4A. Bross NFMCC CM January 15, 2009

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

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.

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– --------

This is a sum over all types: Scientists, Engineers, Postdocs and Technicians
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.
