Scope

Information from Paul Brinza

  • Athena is 3 meters ID and 3 Tesla and has the highest stored energy.
  • Ecce is 1.5 Tesla and is also 3 Meters ID.
  • Core is 3 Tesla but only 1 Meter ID.

The stored energy scales like B^2*Vol.


Additional information from Paul and Pawel:

  • Radial material in the current 3 T CORE solenoid design.
  • Inner vacuum vessel ~ 4 cm Al, density 2.5
  • Inner radiation shield few mm ~ 2 mm Cu, density 9
  • Coil 6 cm - a 5:1 mix of Cu and NbTi (i.e., with Nb =Ti, a 10:1:1 mix of Cu, Nb, and Ti)
  • Coil support cylinder ~ 7 cm Al, density 2.5
  • Outer radiation shield ~ 2 mm Cu, density 9
  • Outer vacuum vessel Al ~ 10 cm Al, density 2.5

The 5 cm of Cu in the coil is not negligible, but also not a dominant contribution.

Question: an EIC KLM would work just as well with Cu as with Al? Belle's configuration and KLM performance will give a good indication
