Dear Ralph,

Your minutes are fine. I have a few minor comments:

- Switching the feedback off in collision is ok. The problem is before,
i.e. during beta squeeze and luminosity steering. 
- You may want to mention the remark by Bernard on the tune spread from
parasitic collisions (to be checked).
- Larger beta functions (gain with 1/sqrt[beta])? Yes, you can drop the
question mark.

I enclose (most of) my slides in electronic form. Unfortunately they
come from different sources and I don't know how to combine them in a
single PDF file (but probably you or Martine know). I will send you a
paper copy for reference.

Have a nice weekend
Francesco
