400μsec @200kW(keeping)

Initial state

Example #2 (5Hz/1300μsec)

KEK-LAL Collaboration in FJPPL 21

upstream downstream

800, 1300, 1500μsec @200kW(but we did not do keeping)

Initial state

1300μsec @200kW(keeping)

There is a correlation between higher temperature at ④/⑤ and electron activity at cold window.
