## SRF Technical Goals

- Develop cavity processing parameters for a reproducible cavity gradient of 35 MV/m; improve the yield of 9-cell cavities for gradient of 35 MV/m in vertical tests .
- Carry out parallel/coupled R&D on cavity material, fabrication, and processing to identify paths to success.
- Assemble and test one or more cryomodules with average gradient > 31.5 MV/m.
- Build and test one or more ILC rf units at ILC beam parameters, high gradient, and full pulse rep rate.
- Develop plans for an ILC Main Linac System Test consisting of several rf units.
- Strengthen U.S. SRF technical capabilities and prepare the U.S. with the infrastructure, expertise and industrial capabilities necessary to host the machine.

- FY07 and beyond technical goals are consistent with the GDE’s and the US Regional Interest Priorities.

## Cavity R&D

- 24-36 cavities from industry in FY07 and x2 number in the following years.
- Industry: Niobium and surface QC to be done by industry. Fermilab could make available Eddy Current Scanner and Surface lab for industry to use.
- We are interested in working with new industry in fabrication and processing.
- Cavity Processing:  Achieve 35 MV/m, 80% in 1st processing

- Tight Loop Processing: 3 Cavities in US
- Bulk EP:  Degrease &  EP 80 m

- Loop: 	 EP 10 m (1 day)
- 	 HPR
- 	 First stage assembly
- X 3	 Final assembly to bake stand
- 	 120 C on bake stand

- Production

- One of many
- Models

- LCFOA Meeting @ Fermilab

## Cavity Infrastructure

- In FY07 the cavity processing  and vertical testing will be done at Jlab, Cornell and ANL/FNAL.
- We will working towards a design of a new pre-industrial facility to be  build in 08-09 at Fermilab.

- European Concept

## Cavity Infrastructure

- In FY07:
- ILC will start Vertical Testing, HPR and Heat Treatment of the Cavities at FNAL
- 1st High Power Test of Dressed cavities in US
- 1st test of US produced and processed cavities

- PHPK

## Cryomodule Design and Fabrication

- ILC Cryomodule working group (Fermilab, INFN, DESY, KEK and CERN) is working towards a design of an ILC cryomodule.
- The Goal is to design an improved ILC cryomodule (Type-IV) and build one at Fermilab by FY08.
- Fermilab is getting a Type-III+ cryomodule kit from DESY (CY06) and fabricating one additional using the US cavities, tuners and couplers by end of FY07.

## ILC Cryomodule Components

- In FY07 (x2 in following years)
- 12 Couplers
- 12 Tuners
- 12 Helium Vessel
- 1 Cryomodule (Cold Mass)
- Klystron
- RF Distribution
- Instrumentation and Controls
- We vision industry participation in assembly of these cryomodule

## Summary

- Fermilab and ILC collaborators have established enough infrastructure for ILC R&D.
- We are rapidly increasing industrial fabrication.
- We are working with industry in transfer technology and fabricate parts in industry. This needs to expand.
- Industry should get involved early to help with industrial practices in design and cost reduction.
- I think LCFOA is doing an excellent job.
