Updating the SCLL Design &ASC Documentation

12ASC Progress New!Continual systems code updates to improve credibility and transparency.Refining of SCLL design.New comprehensive documentation.New ASC Homepage for all ASC-related material.

Oct. 2011 action items for ASC:Focus on updating and completing SCLL designDelay issuing DCLL strawmen until a consensus on new thicker build is incorporatedInvestigate additional 3D printing

1516Summary & Future WorkModifications continue to enhance & clarify the ASC.Comprehensive documentation posted on ASC Homepage:http://aries.ucsd.edu/carlson/aries/

Ready to implement changes to SCLL design as they become available and ready to run further systems analysis.Incorporate any new inputs and modifications into the code, e.g. new builds, compositions, physics parameters, etc.Please call to attention any errors in documentation or updates to parameters/equations within the code.

16173D Divertor Printing

17183D printing what weve learned

Good exercise to evaluate clearances and assembly process.Ambitious goal of printing ~1/2-m scale divertor module.~30x longer printing time than initial part (~200 hours).More material than anticipated ~150 in3 (3 cartridges).Print scale for time constraints.

~50 x 20 cm scale~10 cm scale18
