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
