Description

With a constant MCP voltage I see a factor of 2 decrease in turn 100 between collecting the first 1,000 turns and collecting 64,000 turns (where you see slip stacked beam).

See the attached plots for more details.

History

#1 Updated by Denton Morris about 1 year ago

I'm seeing the sigma fit to a fixed turn change based on the number of turns collected. Constant turn analyzed, constant MCP voltage, but different sigma by over 10%.

Not my problem!
