11. Run 2 Minimum Position Some changes seen Min BCD has drifted upwards over time. Pulse to pulse Variability approx. 0.8mm still well within what is acceptable for MICE Thanks to Ed for new DAQ plots

12. Run 2 Acceleration Acceleration is flat. Variability acceptable. Note that we think we understand difference between old and new DAQ acceleration values.

13. Comments No significant wear/dust after 600k pulses No new wear seen on 2 nd inspection Was wear seen on 16 th “bedding in” ? Next inspection on 31-11-2010 Should be over 1 million pulses on clock
