P1.2 Opening of boxes in LBT Hall, inspection of the contents and installation of units on their handlings

  • Phase : 1
  • Status : Draft
  • Category : Unpack, Assemble, and Verification (C1)
  • Recurrence : once
  • Duration : 1 day

Description

  • Unpack the boxes carefully and visually inspect the components inside.

Prerequisites

  • All the necessary tools and safety features to unpack and move.

Procedure

  • Carefully unpack the boxes containing the SHARK-NIR opto-mechanical components.
  • Visually inspect if all the contents are safe and secure.
  • Inspect if the tilt and shock sensors are activated or not.
  • Check if there is any damage to any part of the shipment. If yes, note them, take photos, and communicate to the respective insurance party (if needed).
  • Set up the handlings for the cryostat and the optical bench. Install the corresponding onto the handling.

Templates

Success criteria

  • No damage to any boxes.
  • No damage to equipements.
  • No hardware out of location.
  • No shock or tilt sensors were activated (TBD).

Notes

  • See AD10 for more details.

LBTO support

  • Crane operator (mountain bay) to lift and move stuff.
  • 1-2 crew to support unpacking and to move.

Result

  • An external inspection of the boxes was performed, and all seals were open. A few outstanding notes.
  • Box-1: some small signs of humidity were seen on the top panel.
  • Box-6: the rusted parts were in a terrible shape and were taken out to be cleaned [this started in Padova but got worse during the trip].
  • Box-13(the one with 5 and 10 G up-down triggered sensors): was found without seals (we discovered the day after that they were opened by Brian or Chris). Inside content was fine at visual inspection.
  • opened box-1 to take out the instrument and re-mounted it empty to be transported to base camp for storage.
  • inspected Box-5: all fine. It was located on a shelf in the high bay for later use in October (?) run.
  • Marco cleaned the rust out of the 2 parts (this was already seen partially in Padova after packing the box), put silicone on them, and re-placed them in Box-6. Later in the afternoon Jacopo and Marco placed all extra pieces from box-7 into box-6. Box-6 is now equipped with wheels.
  • unpacked Box-7, and took out SHARK-NIR handling and the rest of the parts. The ties used to keep in place the metal parts on the bottom were all broken, but parts were shifted by a few cms and no issues were seen.
  • SHARK-NIR was installed onto its handling thanks to LBT crew support
  • The Ultrashock Sensor that was mounted on the Instrument provided the following data:
    • Pressure variation in the range (698.30 / 1017.50) mbar
    • Temperature variation in the range (13.6 / 30.4) °C
    • Humidity variation in the range (35.7 / 68.6) %
    • Shock along the X-axis in the range (-4 / 4) g. One peak of around 4g on (06/24/22 - 07:24)
    • Shock along the Y-axis in the range (-4.0 / 8.6) g. Two peaks of around 8g on (06/21/22 - 13:09) and (06/22/22 - 01:39)
    • Shock along the Z-axis in the range (-0.2 / 5) g, w/o any strong event

Date performed and by whom
