[[TOC(inline)]]

This document lays out the procedures and performance requirements for commissioning the SHARK-NIR instrument. Specifically, it lists the on-telescope activities needed to bring SHARK-NIR online for scientific exploitation starting from unpacking the boxes at LBT.

The commissioning is broadly divided into three phases:
 **Phase 1**: We start from inspecting the boxes at LBT mountain bay, unpacking, and installing the instrument at the mountain lab for alignment verification and functionality checks. All of these are daytime activities.

 **Phase 2**: The activities starting from the installation of SHARK-NIR at the SX central bent Gregorian focus of LBT to the acquirement of the first nighttime telescope collimation model of the instrument form the Phase 2. Most of the activities are daytime. The only nighttime activity is to check the pointing, acquisition sequence, and getting the first nighttime telescope collimation model for SHARK-NIR.

 **Phase 3**: Phase 3 of the commissioning starts from sending preset to the telescope to testing individual SHARK-NIR observation modes for performance to the total SHARK-NIR performance. All the activities are nighttime. By the end of this phase, SHARK-NIR is ready for Science Verification.

Note that the corresponding evolving doc in the SHARK-NIR Dropbox folder is **SHARK-NIR-INAFP-COM-001_CommissioningPlan.docx**. There is also an excel file listing the activities titled **SHARK-NIR-INAFP-COM-002_CommissioningActivityList.xlsx**.

== Additional Information  ==

Note:
 - as of now, there is no one to one correspondence with the evolving doc (eventually they will be the same)
 - you may see that there is some repetition in the activities. this needs to be sorted out eventually.
 - the order of the activities may also be changed later.
 - the details of each of the activity (when you click on them individually) may not be complete and will be refined in time.

To be added:
 1. Nighttime performance activities:
      - Evaluate the seeing performance and Strehl achieved from the LBTI AO in closed-loop and various seeing conditions.

 2. Look-up table activities:
      -  NCPA measurement for different telescope elevations?



Reminders:
 - The space requirements at the mountain bay (@LBT) should be communicated to LBT at the earliest, along with the availability of crane operator, container moving tools, etc. Depending upon the month of the year, the mountain bay can be seriously booked (especially during July-October months due to summer shutdown).
 - The same is true for the cleanroom near the mountain bay. If we need access to the LBTO network in the cleanroom, there are some network ports. But we may need to tell them in advance (Talk to Florian Briegel for more info).
 - Note that if there is any ASM repair/activity scheduled in the cleanroom, preference is always for them and we will have to co-live or get after that.
 - From the LINC-NIRVANA commissioning experience, it is always better to keep the tools associated with a particular alignment together, to avoid looking for it in all the boxes there. Also, there MUST be a **living inventory** wiki page where everyone should note down what is taken and kept in the box/container.
 -  Space required by SHARK-NIR at 3L is already mentioned to JC and CV. Later, we may need to specify the exact area.
 - For activities (P2.4-P2.8) which need the RR to be mounted on the SX side, the source should be a bright broad-band source (including also NIR wavelength). Perhaps, Ocean Optics would do. Also, if helpful, we may use a powerful (green) laser beam for initial alignment checks.

8.4	Installation interfaces
All the checks to verify the feasibility of the installation procedure of SHARK-NIR have been performed on the CAD model “SHARK Installation Final.stp”.  For installation purposes, the requirements to LBTO are:

•	Remove the door of the Nystrom LBTI top hatch (SX side).
•	Installation of the rotator work platform at the central bent focal station, SX side.
•	Use of the dome crane, to lower the subsystems of SHARK-NIR (as described in AD6) through the hatch in the UIAP LBTI platform and from the M1 side.
•	Operator to move the crane.
•	General assistance during the mounting phases.

8.5	Electrical interfaces
SHARK-NIR electronics design is reported in AD5.
-	Summary of required space in the rack (total space: 13U):
o	The motor control unit dimensions are 483mm (width)  x  133,35mm (height)  x  525mm (depth)  (also indicated as 19‘‘ × 3U × 525 mm)
o	The dimensions of the Lake Shore 336 temperature controller are 435 mm W × 89 mm H (2U) × 368 mm D (17 in × 3.5 in × 14.5 in)
o	Custom realized box: (2U in height) may contain the 2 light sources and their power supply, a motorized linear stage (M-403.2DG  from Physik Instrumente), a small optical system consisting of 2 lenses and 1 filter to select the light to inject into the integrating sphere of SHARK-NIR (broadband or multi-narrow bands), the TT camera power supply and the power switches board (relais board)
o	DM electronics is contained in a 19” × 4U
o	WFC BCU housing: 19” × 2U (TBC)
-	Power requirement (total Watt dissipation: 700W):
o	The motor control unit maximum power consumptions is ~350W. 
o	The Camera temperature controller maximum power consumption is of the order of ~100W. Its power requirement is 100, 120, 220, 240 VAC, ±10%, 50 or 60 Hz, 250 VA.
o	The C-RED2 camera needs a 12V power supply and a commercial “relais” board controllable through Ethernet, is required, to power the power supply, which has a power dissipation of the order of 10W.
	Custom box: power to be dissipated of the order of 100W
o	DM electronics power consumption is 150W.
o	WFC BCU: 24Vdc (48Vdc is also possible upon request) and the estimated power consumption is ~15W
The agreed cabinet to allocate the above described electronics is rack 2, referring to Figure 6. The space reserved to SHARK-NIR electronics is the lowest area of the cabinet.

 
Figure 6: the agreed cabinet for SHARK-NIR electronic is #2.
8.6	Thermal interfaces
-	Cooling:
o	Daily refill of the cryostat: one LN2 refill per day is required (~10 liters). The camera LN2 hold time is of the order of 28 hours (computed in very conservative conditions, see AD7), giving a reasonable margin on the refilling time.
o	Liquid cooling of the technical camera C-RED 2 from First Light (through LBTO glycol system, described in RD9):
	Max temperature: 35°C 
	Min Temperature: dew point
	Pressure: 10 bar max  
	Cooling capacity: 100W minimum
	Flow rate: > 0.5 L/min 
	Max 50% ethylen glycol aqueous solution ; 50% distilled water or deionized water

8.7	Other interfaces
-	Air Flow:
o	A clean air flow with a maximum required flux of 0.5 m3/min to keep SHARK-NIR optical bench on a slight over-pressure with respect to the outer environment.   
8.8	Logistics 
8.8.1	Connections
An Ethernet cable should reach the computer rooms located at level 2.
8.8.2	Storage
Space (TBD) for storage should be made available at 3L.
