- **Phase**		:	2  
- **Status**		: 	[[span(style=color: green, **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
 
**Templates**

**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
