Abstract:
A statement in the requirements for the new BPM electronics is that the
differential resolution not exceed 7 microns (one sigma).
This note discusses how such a measurement can be done, and how accurately
sigma might be measured, given the availability
of only one prototype of the new BPM design.
The result is that sigma can be measured to 15% accuracy using a sequence of
35 3-bump measurements, or if 30% accuracy is adequate, a sequence of
14 3-bump measurements.
