Today we will be doing the real k measurement for RF optimisation.
Uesugi-san presented some slides on RF optimisation using experimental k. The k values from the data taken on 27/4 seems quite low and varies quite a lot. We hope that with more data today things will become clearer.
He also raised one issue of timing which we haven't yet included in detail in the analysis - we measure the beam loss from injection point which is not necessarily the start of the RF timing. He looked at the measured k for ±0.2ms offset in timing.
Suzie showed some slides from Shinji on dispersion at the foil measurement and a few plots of dispersion. There was some discussion about the dispersion and how to analyse it without making too many assumptions about k-value etc...
