Bunch-by-Bunch Analysis of CESR-c Optics


Lattice: fit_postop_20070116

30 March 2007

---

Present operational 3770 lattice, obtained by fitting phase and writing out lattice file in CESRV (mjf).

Operating bunch configuration (24 bunches): t1-8.b3-4,t2-9.b5 4 mA/bunch max.

BBI compensation obtained via PCBETING knobs. These include coefficients tuned to compensate both the IP and the LRBBI at the parasitic crossings. The coefficients can be seen in the file bbi_beta_00252ip_mgb2.com. The knob strengths are proportional to positron bunch current, with the zero point at a value for the bunch current of 2 mA/bunch.
