    keyword=Target cool-down and CHL flow

    The helium target vented at at ~5:40 am due to CHL flow droping.
    We took a controlled access, closed vent valve. Changed to a new helium bottle. Started cool-down. During the cool down, CHL dropped
    to <4 g/s from ~17 g/s. The vent valve openned twice. I had to close
    it as soon as it openned to save the gas. CHL eventually (after ~5 minutes) came back to 16 g/s. During the CHL flow drop/recover, we did not change the J-T valve. We are still in the process of cooling-down the target, about half way now.
