keyword=Dithering parameters modified
I modified the dithering parameters to try to make the most of the dithering
cycles. First, the ticks per step from 18->24, which should provide more data
in each dither cycle (though fewer total cycles, and possibly more cycles
corrupted by beam trips or such).
I modified the amplitudes as well:
getConfigBMW()
bmwCient::: listing Coils, number of cycles, and amplitude...
coil: 0 Number of cycles: 1 Amplitude = 150
coil: 1 Number of cycles: 1 Amplitude = 150
coil: 2 Number of cycles: 1 Amplitude = 150
coil: 3 Number of cycles: 1 Amplitude = 450
coil: 4 Number of cycles: 1 Amplitude = 450
coil: 5 Number of cycles: 1 Amplitude = 150
coil: 6 Number of cycles: 1 Amplitude = 300
coil: 7 Number of cycles: 1 Amplitude = 30
I updated these defaults in the BMW code, so they should be robust over IOC
reboots.
Figure 1 below shows the amplitudes seen from this configuration, tested at the
end of 5772 and implemented from then on.
