1
EE Support TEV Abort Inputs
  • HOPS (QFA4, QFE1, QFF3, QDD1, QDE2, QDF4, SF,
    SD, SQ)
  • Abort Power Supply OFF
  • DIPOLE CORRECTORS (275 PSs located around ring)
  • Abort Power Supply OFF
  • C0 SHUNT (TC0SH)
  • Abort /- 0.5 amp or greater regulation
    error
  • 100 amps maximum
  • 11 amps/sec max. slew rate
