Abstract:
It has been observed, that the optical properties of e-cool solenoid doublet SA6 changes while its current stays the same (Sasha, Lionel). It looks as number of turns changed.
Optical properties of the lens can be measured by the differential orbit measurements: downstream BPMs versus upstream correctors. This measurements allow to restore the lens nominal optical properties by correction of its current.
