Low charge might be preferable to reduce the impact
of the wakefields. Anyway our algorithms should
work with any set of beam parameters.

10 Hz or more, as we need at least 100 orbit
measurements to achieve the required precision.
30 Hz would be preferable.
We would need a stable machine and constant beam
parameters during the whole experiment: We
measure the response of the beam to each individual
corrector in ~3-4 hours. The tests of 1:1 corrections
and DFS take 4-5 hours in total.
As the emittance reduction is our ultimate goal, we
need to measure the emittance multiple times. This
takes quite some time.
