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.

Naming structure of the commissioning activity

Each commissioning test/activity has a unified structure as follows:

---

Name of the commissioning activity

• phase: states the phase of the commissioning (1/2/3)
• status: reports the current status of the test (draft, final, complete)
• category: one of the categories mentioned above
• recurrence: describes how frequently the test must be executed
• duration: estimates the time required to complete the test

Description

• Contains a general description of the test

Prerequisites

• Lists items that must be in place before the test begins

Procedure

• Explains in detail how to execute the test

Success Criteria

• Enumerates the outcome associates with successful completion of the test

Notes

• Additional supporting information

LBTO Support

• Mention if (and what) support required from LBTO

Associated SHARK-NIR personnel

• Mentions here who are the associated personnel to the test

Date performed and by whom

• Mentions who performed the test and when

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.

Comments

MDP

• all operation that should be supported by control software automated procedures should be defined by the responsible person with software person in copy or in accordance with software department (better) (e.g.: P1.8 and P1.9)

Reminders

• check if all the installation of interfaces is mentioned and in the right places. if LBTO support is needed (crew, crane support, etc.), mention those.
• make sure if all the support from LBTI and iLOCATOR team are mentioned clearly (related to the installation of electronics in their cabinets, sharing space, access permissions, IP addresses, etc.)
• need emergency stop buttons in SHARK-NIR? If so, need to integrate them into the LBT control system?
• check if all the electronics related support and requirements are mentioned.
• check if all okay for the LN2 fill and glycol/cooling water flow, etc.
