Summary and Conclusions
- This talk presented a sample of a few techniques (in reality a lot more was done), which have brought a significant (both in a qualitative and in a quantitative way) advances in the field quality in accelerator magnets.
- A design and analysis approach (which quite often ran against the conventional wisdom) worked well because of a systematic and experimental program.
- From a general guideline on field quality for VLHC (in reality, it is yet to be developed and should be done in close collaboration between accelerator physicists and magnet scientists, the RHIC model). However, it appears that all magnet designs should be useable in VLHC from field quality considerations.
- However, one should not take it for granted; a consistently good field quality in RHIC magnets was a result of several things. Moreover, it can be further improved with more innovative ideas. Given the time available for the next machine this is the time to explore the ways for reducing magnet costs while maintaining a field quality that is acceptable for VLHC . Conversely (and perhaps together), one should also examine if magnet costs can be reduced significantly by relaxing parts and manufacturing tolerances.
