Indian Laboratories: Fermilab’s Interest Fermilab would like the Indian Institutions to participate in Project-X research, design, development and construction. Fermilab and Indian labs are developing SRF infrastructure. –Joint development allows sharing of resources and advance the schedule. Indian Institutions would develop the designs, prototype, and fabricate different components for the Project-X SRF accelerator. –Spoke resonator cavity and cryomodule parts (with IUAC and BARC) –  = 0.8 cavity, tuner, helium vessel, etc. (with BARC, RRCAT and VECC) to produce a dressed cavity and cryomodule parts –Cost optimization of cryomodule Indian Institutions would develop the design and fabricate a VTS Cryostat, HTS Cryostat and CTS Feed can and End Can for installation at Fermilab –Similar setup established at Indian Institutions to support the above development and Indian accelerator Program.
