DOE Review of FNAL Superconducting Magnet Program

1. DOE Review of FNAL Superconducting Magnet Program • Welcome ! • Introduction • HEPAP long range Plan for HEP • Recommendations from April Internal Review • Agenda • Logistics DOE SC Magnet Review

2. Introduction • Fermilab is a single purpose Laboratory whose mission is High Energy Physics research. • Superconducting Magnet Technology is one of theenabling technologiesrequired by FNAL to build and maintain the accelerators necessary to accomplish this Mission. • At FNAL, the Superconducting Magnet R&D program is located in the Technical Division. DOE SC Magnet Review

3. Introduction • TheMissionof the Technical Division at FNAL includes “The development, design, fabrication or procurement, and testing of accelerator and detector components.’’ • The Superconducting Magnet R&D Program in the Technical Division is intended to serve both the Division’s laboratory mission AND to serve the overall national long-range high energy physics plan (as outlined by HEPAP). DOE SC Magnet Review

4. HEPAP Long Range Plan(Jan 2002 HEPAP Subpanel Report) • 1st Priority: Exploit existing HEP facilities • For FNAL TD = support Tevatron Collider for Run II • SC magnet repairs + specialty magnets if required • Next: Support US participation in the LHC • Now: = production of the 1st Generation IR quads. • This is in progress. (tour) • 1st generation quads are known to have limited lifetime due to radiation damage. (approx 6-7 yrs at full L ) • Long lead times  must start soon on 2nd generation IR quads • more radiation hard, higher instantaneous L. • Developing these quads becomes an important part of our long range magnet R&D Plan DOE SC Magnet Review

5. HEPAP Long Range Plan • VLHC • “Beyond the linear collider, a Very Large Hadron Collider(VLHC) is an important long-range objective for our field. ” • The 1998 HEPAP Sub panel recommended”an expanded program of R&D on cost reduction, enabling technologies, and accelerator physics issues for VLHC.” • “Detailed specifications for the VLHC must wait for physics discoveries at the LHC.” • eg high field vs low field staging options DOE SC Magnet Review

6. HEPAP Long Range PlanJan 2002 HEPAP Subpanel Report • “…since a VLHC is so central to the long-term goals of our field, we strongly support R&D toward such a machine.” • Funding continue at ~ the same level • “…take a long-term perspective toward developing new technologies and techniques relevant to such a machine. ” DOE SC Magnet Review

7. Recent Internal Review • As a New Division head and in preparation for this review I requested an internal review of the Technical Divisions Superconducting magnet program. This review took place on April 25-26, 2002. • Excellent Committee: J. Peoples (Chairman), S. Gourlay (LBNL), J. Strait (FNAL), S. Van Sciver (NHMFL), and P. Wanderer (BNL) • A copy of their draft report has been included in your handouts. • I will review briefly their findings and recommendations. DOE SC Magnet Review

8. Findings and Recommendations from April Internal Review • Tevatron Maintenance and Spares • Maintenance and spares program for Tevatron is effective • Should do a more systematic assessment of the value of various Tevatron improvements like HTS leads and re-coolers for spool pieces • Should complete ongoing spares and vulnerability assessment in collaboration with Beams Division • LHC Program • Positive about Fermilab Technical Divisions role in LHC IR Quad development and production • Appropriate to begin R&D for 2nd generation IR quads at this time because of long lead times for this development • Collaboration with LBNL, BNL was working well and should continue for 2nd Generation IR quad program DOE SC Magnet Review

9. Findings and Recommendations from April Internal Review • High Field Magnet R&D • Committee was generally positive about overall progress on Nb3Sn technology, design studies, cos q dipole program, common coil approach to dipoles, racetrack coils for fast turn around, etc. • “47 contributions to conference proceedings and papers is and impressive output for just two and a half years”… but: • “Fermilab Program has not benefited as much as it could from experience and current work of other magnet programs, in particular those of LBNL and BNL” • Materials R&D and testing facilities • Generally positive comments, “superb infrastructure” • “Development of Nb3Sn wire is a challenging and essential objective..” but: • Effort should be more closely integrated with the national program managed by the DOE office of Science DOE SC Magnet Review

10. Findings and Recommendations from April Internal Review • Management and scope • Magnet program in Tech Div has been “effective” • Responsive to HEPAP recommendations • “Size and organization in TD is well adapted for the needs of Fermilab and the national super conducting magnet program” • Recommended that FNAL continue to support the Tevatron, High Field, and materials programs at the current level • Recommended that FNAL commit to be a major participant in the LHC 2nd generation IR development • Improve communications with other labs via mini-workshops • Conduct reviews of model magnets (with advice from other labs) • Division head should appoint an advisory committee • We clearly are interested in the recommendations from this review as well, but already we have begun planning for changes as a result of this internal review DOE SC Magnet Review

11. Response to Internal Review Recommendations • The head of the Technical Division ( ie me ) will appoint an Superconducting Magnet Advisory Committee (SMAC) to monitor and evaluate progress on superconducting magnet technology in the Technical Division and provide advice to the Division Head. • Representation also from LBNL, BNL, and perhaps NHMFL will help improve lab-to-lab communications • Conduct design reviews of model magnets before construction • Improve communications and information flow with other labs • We will seek closer collaboration with the other labs on common issues. (eg splices  work more closely with LBNL) • We will plan to host one or more mini-workshops each year at FNAL on accelerator magnet technology. • Plan to set up regular meetings with other labs both as part of the LHC 2nd generation quad effort and to use these meetings to exchange technology information of a more general nature. • Again, we welcome your comments and recommendations DOE SC Magnet Review
