    8 •       Cooldown the cryostat.
     10- Cooldown the cryostat.

    912**Prerequisites**
    10 •       SHARK-NIR connected to LBT network.
    11 •       Electronics cabinets on.
    12 •       Needs vacuum pumping at the beginning (vacuum pressure of 10e-5 Torr is good (see the cryostat manual SHARK-NIR_SO-MAN-001)).
     13- SHARK-NIR connected to LBT network.
     14- Electronics cabinets on.
     15- Needs vacuum pumping at the beginning (vacuum pressure of 10e-5 Torr is good (see the cryostat manual SHARK-NIR_SO-MAN-001)).
     16
    1317**Procedure**
    14 •       Start the cryostat cooling down sequence (see the cryostat manual SHARK-NIR_SO-MAN-001).
    15 •       Check how the system is performing every 30 minutes.
    16 **Success criteria**
    17 •       Cryostat cooled down without any issues.
    18 •       The temperature at the detector is stable at ~78K.
    19 **Notes**
    20 * This activity can run in parallel with other cleanroom activities (which do not need a cold detector).
     18- Start the cryostat cooling down sequence (see the cryostat manual SHARK-NIR_SO-MAN-001).
     19- Check how the system is performing every 30 minutes.

    26 •       Liquid Nitrogen refill is required in the cleanroom.
    27 * Vacuum pump and support for cooling down the cryostat.
    28 **Associated SHARK-NIR personnel**
     31- Liquid Nitrogen refill is required in the cleanroom.
     32- Vacuum pump and support for cooling down the cryostat.
