CBETA Splitters

Splitter line magnet polarity convention

For bipolar dipole magnets:
  • Horizontal: Positive current = beam to the outside of the ring


  • Vertical: Positive current = beam up

For bipolar quadrupole magnets:
  • Positive current = horizontal focussing


For unipolar magnets, magnetic field direction is determined by the lattice

Splitter line 4 Septum magnets

Septa 2 magnet assembly (7207-014-062019.pdf, 6/20/2019 D. Burke)

A total of four septum magnets are required to be installed in the 150 MeV splitter lines for the CBETA machine - 2 in the SX line and 2 in the RX line.
