P2.3 Basic functionality, Instrument Operability and Functioning

• Phase : 2
• Status : Draft
• Category : Daytime testing (functionality and operability) (C3)
• Recurrence : once after instrument installation at telescope platform
• Duration : 1 day

Description

• Activating the instrument after the installation of SHARK-NIR at the telescope platform. Verification of the shutdown procedure.
• The functionality and operability of individual components/sub-systems are tested. Verification of the internal alignment of the instrument is performed using the light source within. The final step is the performance of the system.

Prerequisites

• SHARK-NIR is installed on the LBT telescope platform.

Procedure for Basic Functionality

• Switch on all the cabinets, follow the instrument telemetry and see if the telemetry is logging.
• Turn all the hardware subsystems turned on and start all the corresponding services. Check all the logs from the services.
• Check the shutdown procedure.
• Testing the electronics and SW rotation of the knob controlling the cool down process (LBTI side).

Procedure for Basic Functionality

• Initialize all the motors/sub-systems.
• Check the functionality of all the motors (home position, named/nominal positions, and reaching software limits).
• Check the working of all the light sources.
• Using the on-axis diffraction-limited light source, check the internal alignment of the SHARK-NIR.
• Check the relative positions of the coronagraphic masks.
• Check for on-axis optical quality.

Templates

Success criteria

• Activating instrument successfully.
• All systems are turned on, and the services are all running without any errors.
• The shutdown procedure is checked and working as it should be.
• Motors and light sources are working as they should.
• The internal alignment is preserved.
• Performance of the system is acceptable.

Notes

LBTO support

• Testing the working of the knob (motor or manual) controlling the cooldown.
• Liquid Nitrogen fill.
• Vacuum pump (See activity P1.4 and P1.5 for more details).
