    keyword=left Q2 nitrogen level - can ignore

    We are still waiting for beam studies to be completed, and taking lots of pedestal/cosmic runs.

    David L. notices that the left HRS Q2 nitrogen level is low (17%). We phone Ed F. who tells us not to worry, this is a long-standing problem that the Techs are well aware of. It is not a significant issue, since the nitrogen shield is not a great system anyway, and it just means that we draw a bit more coolant from ESR. We have apparently run for many weeks with the nitrogen level low or empty.
