Look Forward: Opportunities & Challenges<br />
• Impact ILC gradient re-baseline<br />
o AAP Review at TILC09, GDE meeting at KEK, April 17-21, 2009.<br />
• Help increase US industry’s SRF competence<br />
o Specification of processing parameters to be adopted for industry application.<br />
o Train US industry for high gradient cavity processing.<br />
o Feedback knowledge (material, processing and fabrication).<br />
o Participated North America Cavity Vendor Meeting at FNAL , March 6, 2009.<br />
• Provide technology option for J<strong>Lab</strong>’s own future machine<br />
o Raise cavity Q performance at 20-25 MV/m gradient by BCP + EP.<br />
o Two examples with 7-cell HG shape cavities (next slide).<br />
• Further impacts limited for lacking of a ILC project role<br />
• Infrastructure stressed and envelope being pushed<br />
oBreakdown & bottleneck increasingly painful because of heavy use & aging.<br />
o Re-investment necessary for sustained competence in high gradient SRF.<br />
