keyword=setting up HRS right magnets
On setting the right arm, the magnets slwoly settle in, but Q1_right oscillates dsue to a bad bit (with regulation on), as shown below. Doug suggests we find a setting close to the momentum setting, 1.201 GeV/c, where that bit is not used, so Q1 is stable. Jack finds this is 1.19635 GeV/c. We adjust the spectrometer set momentum to this value, and the 2-minute period oscillation goes awayn- the very last part of the image below.
