    This entry is a followup to: 102986

    keyword=Septum Current Tests, pt 2

    Before we got to a limit of read = 391A (see 102952). Then at midnight we ramped down and then back up and go stuck at 386.5A (see 102986). At around 0600 we changed to a lower momentum settings (see 103018). i recorded our ramp down from read = 386.5 A to 371.5 A. the data is below. see Fig 1. the circles are from from our first test. the crosses are from the momentum change ramp down. is this some sort of hysteresis effect?
