P1.3 Installation of SHARK-NIR HW and electronics in clean room

• Phase : 1
• Status : COMPLETE
• Category : Unpack, Assemble, and Verification (C1)
• Recurrence : once
• Duration : 1.5 days

Description

• Install and integrate the different SHARK-NIR opto-mechanical components onto the mechanical structure. Install the electronics into a temporary rack, and move the unit to the cleanroom.

Prerequisites

• All the necessary tools and safety features to do the installation, integration, are in the cleanroom. The mechanical structure to hold SHARK-NIR should be assembled and ready to be used.

Procedure

• Carefully integrate the cryostat unit with the derotator-optical bench unit.
• Before installing the electronics into a temporary rack in the cleanroom, take it to the LBT Platform cabinet at Level-6 (its final destination) shared with iLocater for sanity checks.
• Set up the electronics racks in the cleanroom.

Success criteria

• The SHARK-NIR is primarily assembled onto the mechanical structure.
• The motor electronics rack fits perfectly well at the LBT Platform cabinet (its final destination) shared with iLocater. If not, communicate with the responsible person with the changes required.
• Electronics racks are set up and ready to use.

Notes

• See AD11 for more details.
• Info from Laura Funk (via Slack): "Pat measured the footprint of the clean tent. It measures 2.7m X 3.5m (inside the tent and frame boundary)". Added on 2 March 2022
• Precautionary Warning to INAD-PD People: Before installing electronics in the cabinet, do NOT forget to remove the fan from above DM electronics. To perform this operation requires opening the DM electronics (see image below).
• Note for INAF-PD people: Remember to test the deployable arm stage after shipment and its working.

LBTO support

• Crane operator to lift and move stuff (mountain bay and/or cleanroom). In particular, a crane operator is needed to install the instrument and other components to their handling. Refer to AD11 for details.
• Forklift to move boxes.
• 1-2 crew to support installation procedure (mountain bay and/or cleanroom).
• Access to the LBTO electronics cabinet (Level 6) where the motor rack of SHARK-NIR will be installed.
• Optical bench - Newport model RS 4000 already available in LBTO is fine. The minimum size of the optical bench we need is 900mm X 1800mm. Note that the optical bench may not be required at all. We request here, however, in case, for any reason, we need to open the cover of the SHARK-NIR bench and need some intervention.
• Access to the clean tent (of an area of 2.7m x 3.5m would be sufficient with the optical bench inside).
• Normal supplies for the clean tent (apparel, head covers, nytril gloves, shoe covers, etc.)
• A desk (100cm x 60cm area), not necessarily in the clean tent, but in the cleanroom area where we can place two laptops, and 2 monitors, etc.
• If LBTO has an electronics rack available to mount the SHARK-NIR electronics for the duration from unboxing to installation at the telescope platform, SHARK-NIR can avoid shipping what we have from Padova. What we have in Padova has the following dimensions 58cm x 71cm x 185cm approximately, but a shorter one would still be acceptable for us. Below is the photo of our rack in Padova. Added on 25 May 2022: LBTO has a rack which SHARK-NIR can use (see image below). In Leroy's words, the "rack we have has 52.75in of mounting space. This works out to approximately 30U." [Email received on 30th March2022].

Result

• Newport optical bench, a table, monitor, and keyboard were brought by the LBT team to populate the clean tent as per SHARK-NIR requests. UPS is already baseline for the clean tent plug.
• SHARK-NIR on its handling and Zarges boxes 10,11,12,13,16 were brought into the clean room.
• Electronics were mounted on the rack.
• SHARK-NIR and rack were rolled into the clean room, ready for cabling.
