Towards 1.3GHz: 2008-09 developments B i 1 3GH it t ti• Begin 1.3GHz cavity testing program in ISAC-II clean room– One single cell sourced from
FermilabFermilab– Bath cryostat in preparation– Sub-atmospheric pump for 2K
operation sourced and testedp– Will develop LLRF in house
• Begin cavity fabrication at PAVAC with processing at TRIUMFTRIUMF– Fabrication dies sourced from
Fermilab Goal:– Goal:
• Two single cell cavities in the nextsix months
• One nine-cell cavity by the end of y y2009
