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

• Phase : 1
• Status : Draft
• 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).

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.
