HTS Magnets for IR Upgrade
Are we ready to build HTS accelerator magnets?
Given the time frame of upgrade, the right questions to ask are:
Is there a possibility to demonstrate the viability of HTS magnets in time for making a technology choice for luminosity upgrade?
Based on short HTS coils (yes we have built and tested a few), itís promising. But itís too early to tell without more R&D and proof.
What is the impact of HTS on overall IR upgrade design?
HTS magnets with very high fields may be enabling technology for some designs (layouts). But, the benefits must be examined in all lattices to see how each can benefit. Modification in strategy?
What is the impact of HTS on high luminosity operation?
HTS can tolerate several degrees (even up to 5-10) increase in temperature. That changes many design principles.
