Coupling Beam Transfer Function Measurement Yun, Al, Henry 2018 May 09, APEX Session
General ● We had 2 hours as planned. ● Ramped up 12*12 Ru+ ion bunches. Fill 21660. Experiment done at store stone of energy ramp. ● Scan family 2’s strengths, measure eigenmode projections, and BTF ( twice at each point ). ● Data are clean and reliable. Good for benchmark with BTF simulation. ● No more time required for this experiment.
