Success criteria

• SHARK-NIR is successfully installed on the LBT platform.
• SHARK-NIR electronics are successfully installed.
• Telescope is balanced.
• Connect all the cables and secure them.
• Reassure all the connections, nuts, bolts, etc.
• Confirm the safety and security of the instrument and the area.

Notes

• Activities on High-bay and telescope.
• Note that SHARK-NIR is NOT installed as a single piece. The cryostat has to be disassembled from the bearing before the installation can start. Please look into the AD3 document for details.
• Note that one (or two) rack(s) of the SHARK-NIR electronics are installed within the LBTI electronics cabinets (shared with LBTI and iLocater).
• Input from Laura Funk (LBTO): Installation of the LBT work platform takes around 2 hours and of course also its removal. If the telescope installation is performed during the observing semester, carefully plan activities that can be completed so as not to interfere with handover for nighttime observations (~2 hours before sunset).
