2. 26 October 2010IIFC meeting, RRCAT Introduction SSR1 Present Status 1.3 GHz Single Cell Other Cavity development

3. 26 October 2010IIFC meeting, RRCAT Under an MoU between IUAC and FNAL, two Niobium Single Spoke Resonators - SSR1 (  =0.22, f=325MHz) are being built by IUAC. The Outer SS vessel would be built and jacketed around the niobium resonators at FNAL. Fabrication of two Single Spoke Resonators, SSR1

4. 26 October 2010IIFC meeting, RRCAT Niobium material received from FNAL ~ Sept. 2007 Technical discussions & negotiations with vendor started in January - March 2008. Work started by the vendor in October 2008. Expected to be completed by 31 st March 2011

5. 26 October 2010IIFC meeting, RRCAT Dies (using mild steel) made and components made in Copper Dies fine tuned and corrected to reduce variations. Subsequently Nb components were formed.
