P2.2 Installation of SHARK-NIR and its electronics on the LBT platform

• Phase : 2
• Status : COMPLETE
• Category : Installation of SHARK-NIR at LBT platform (C2)
• Recurrence : once (unless deemed necessary to remove SHARK-NIR from the telescope platform)
• Duration : 7 days (including 1 day contingency)

Description

• Aligned SHARK-NIR is prepared for the Big-Lift and installed on the LBT platform.
• Installation of the electronics in the cabinets, cabling, and confirming the safety & security of the instrument and area.

Prerequisites

• SHARK-NIR is aligned and ready for the lift-off.
• People required to access the electronics platform have completed the needed training
• Equipment temporary connected to the rails interfering with installation removed (by LBTO personnel)

Procedure

• Look at the AD3 document for the detailed procedure.
  • SHARK-NIR and its parts will be ready on the high bay. These components may be moved through the hatch to the telescope or moved by elevator to the telescope
    • shelves: use elevators
    • rails: use elevators
    • calendered structure: use elevators
    • shark-nir bench+ bearing on its red handling: lift up through the hatch.
    • camera on a cart with wheels (with a window on the bottom): lift up through the hatch or use elevators
  • Day 1
    • Shelves installation. (Pag. 70-89 of Installation Plan: SHARK-NIR-INAFP-MAN-001_Issue2.1) -Temporary installation of rails to identify interferences. Need to be disinstalled at end of the day, unless LBTO advises differently.
  • Day 2
    • 2 Rails installation. (Pag. 90-95 of Installation Plan: SHARK-NIR-INAFP-MAN-001_Issue2.1)
    • Installation of calendered structure on the shelves. (Pag. 95-111). At the end of the day calendered structure shall be secured to the shelves, otherwise it shall be removed, together with installation rails and procedure repeataed the next day.
  • Day 3
    • Install the SHARK-NIR optic bench on the calendered structure. (Pag. 111-141)
  • Day 4
    • Fix the cable chain. (Pag. 142-144)
    • Install patch boxes. (Pag. 144-145)
    • Fix cable from patch-boxes to instrument.
  • Day 5
    • Move the calendered structure at its final position. (Pag. 145-148)
    • SCICAM installation with MACIE already installed. (Pag. 148-163)
    • Installation of electronics and cabling from patch boxes to cabinets.
    • Prepare the deployable arm for its handling. (Pag. 164-171)
  • Day 6
    • Installation of the deployable arm. (Pag. 172-177)
    • Complete cabling.
    • Check movements of bearing, deployable arm, and shutter.
    • Cool down Cryostat.
    • Check the network connections and very basic functionalities after powering on.
  • Day 7
    • Contingency

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 othe Lakeshore of the SHARK-NIR electronics is installed within the LBTI electronics cabinets, the rest of the electronics is in the cabinet shared with iLocater.
• check this link (​https://docs.google.com/document/d/1r0SDiy9yBEfGQjDI6hCXT9hfRDRJ4dh4nNUZ3JHClJE/edit) for some details on the alignment day to day plan.
• Considering October timelines, as per LBTO information. Platform installation can start at 08:00 and takes about 40 minutes. 2 people can handle it. Platform use stops at 16:00, and dismounting takes about 30 mins.
• No extra crew is needed on the telescope during weekends for the platform, as the operation can be handled by personnel already available at the telescope.

LBTO support

• Crew members' support for the preparation, lift-off, and installation of SHARK-NIR and its electronics
• Crane operator (cleanroom, mountain bay, LBT platform)
• Safety officer
• Working platform installed in front of the Gregorian focal-station SX
• Hatch door SX on the UIAP platform removed
• Support for the installation of electronics in the LBTO cabinet
• Liquid nitrogen fill
• Vacuum pump to pump down cryostat (See activity P1.4 and P1.5 for more details)
• Kindly check the installation document, AD3, for more details
