Hi Mark,

These are the best summaries of the excess current and subsequent drops we see with beam from Anu (cc here).

They are under the conditions of:

  *   1 pass configuration with LH2 target
  *   2 pass configuration with LH2 target
  *   2 pass configuration with LD2 target
We can use this email to comment further on limits and considerations for future running.

-Holly
