    keyword=target cooldown started.

    Started target cooldown procedure about half an hour ago.
    Called MCC to request 15K cool-down at 1:50 pm. Informed cryogroup.
    Before the cooldown started, scattering chamber vacuum is about
    2 * 10-5. Now is cooldowning the tarnsfer lines.
    The whole procedure is expected to take about 3-4 hours.
