Revision as of 14:29, 9 May 2019

  • The MCC Hall C energy measurement tool needs to be updated to have the correct dipole map.
  • Beam energies in the table are from separate code using the dipole string current listed in table.
  • Synchrotron radiation is calculated for the full 34.3 deg bend of the Hall C dipole arc.
