3.1. General Comparisons
3.2. Magnetic Field Double Integral Comparisons
- I2bh—double integral in homogeneous constant magnetic field of 4.000174 T, that corresponds to the central magnetic flux density in the baseline configuration of the magnetic system.
- I2bi—double integral in the real inhomogeneous magnetic field of the baseline configuration of the magnetic system.
- I2mh—double integral in homogeneous constant magnetic field of 4.243783 T, that corresponds to the central magnetic flux density in the minimal steel yoke configuration of the magnetic system.
- I2mi—double integral in the real inhomogeneous magnetic field of the minimal steel yoke configuration of the magnetic system.
4. Discussion
- 6% larger central magnetic flux density.
- 13.2% smaller compression axial force and pressure in the main coil middle plane.
- 16.2% smaller radial pressure in each forward coil.
- 12.1% shorter radial distance to the acceptable safety level of the magnetic stray field.
- 7.2% shorter axial distance to the acceptable safety level of the magnetic stray field.
- 3.2 to 8.1% larger magnetic field double integrals and, thus, better transverse momentum resolution of the charged particle registered in the inner tracker.
- 0.97% larger axial attractive force onto each forward coil.
- 9.3% lower magnetic flux density in the transition region between central and each forward coil.
- 5.8% larger stored energy in the magnetic system.
- 61.3% larger radial pressure in the main coil.
- The compression axial force to the central barrel wheel of 236.9 MN each side is 2.92 times larger than the similar axial force in the CMS magnet yoke at the 3.81 T central field.
- The attractive axial force to the yoke endcap assembly of 164 MN from each side is 2.42 times larger than the similar axial forces in the CMS magnet yoke at the 3.81 T central field.
