Goals of the Workshop
We want to develop the industrial model that would be the best for the cavity and cryomodule production for the ILC, and look forward to cost reduction embodied by new processes or manufacturing techniques
This includes:
The project-industry relationship
Quality control
Scale-up to production quantity
Cost--effective manufacturing

Some issues
The aim:
The ILC is a global project
Industry equally must be distributed around the world
Multiple cavity vendors strongly desirable

6. Some issues: industrialization
Advances in industrialization studies since the 1st workshop in Kyoto
“factory” has to be owned/leased by government, because the ILC is a project and not a business (what to do at the end of the project)
Industrialization studies in Japan have shown the value in having this done at a hub lab
Many companies showed that they could achieve ILC-type scale up
Note that this in some cases requires using entire company throughput
Companies see SRF as a growing industry
Coming from different backgrounds and areas of expertise 
SRF is an enabling technology, expect to be similar to example of superconducting wire for magnets – expect mutual benefit
Factory should be close to hub laboratory because of difficulty to find skilled personnel
Example of large local skilled workforce
A great deal of understanding has come from industrialization associated with XFEL as well

7. 2nd SCRF Cavity Technology and Industrialization Workshop / Chicago
Some issues
In many cases, specification reasoning to industry is not clear
We have come a long way on this… especially thanks to XFEL
Example of Nb sheet specs
Example of large-grain material
Build-to-print is not really build-to-print, because this is not really production yet
We also do not know all of the key points, but we know what works!
In many cases, information from industry about how to effectively go after the most important specs is also not clear
Which are the cost drivers for the niobium sheets, and where can we reduce the costs, e.g., round sheets.
What is most valuable to go after?

Summary
Plenty of work to go! Please me with your comments and clarifications, I will (try to) include them in a summary to be posted.
