Henderson, in Proceedings of the 1997 Particle Accelerator Conference, Vancouver, Canada (IEEE, Piscataway, NJ,1998), p. 1765; a follow-up article describing the normalization program was D. Sagan, in Proceedings of the 1999 Particle Accelerator Conference, New York (IEEE, Piscataway, NJ,1999), p. 2969.

7. Since a pretzeled orbit is used to separate the beams (which share a common beam pipe), the sextupoles affect the Twiss parameters and thus need to be monitored.
