P1.11 Science detector calibrations

• Phase : 1
• Status : Draft
• Category : Unpack, Assemble, and Verification (C1) + Daytime calibration (C4)
• Recurrence : starting from commissioining. daily/weekly/monthly/yearly depending on individual activities.
• Duration : 1 day

Description

• Calibration and testing of the SHARK-NIR science detector

Prerequisites

• SHARK-NIR connected to LBT network.
• Electronics cabinets on.
• The cryostat should be running and cooled down.
• Internal alignment of the SHARK-NIR is verified.

Procedure

• Check bias calibration & master dark scripts and then perform the following daytime calibration procedures below.

Code	Activity	Location to perform this test
SDC1	Instrumental background for science	Padova / LBT cleanroom / LBT Platform
SDC2	Instrument flat field, detector linearity and bad pixels	Padova / LBT cleanroom
SDC3	Wavelength calibration	Padova / LBT cleanroom?
SDC4	Thermal background	Padova / LBT cleanroom / LBT Platform
SDC5	Detector gain	Padova / LBT cleanroom / LBT Platform?
SDC6	Detector persistence	Padova / LBT cleanroom / LBT Platform?
SDC7	Spectral resolution	Padova / LBT cleanroom
SDC8	Ghost calibration	Padova

• Check the working of all the detector read-out modes and windowing possibilities. Note that this will be checked rigorously in the Padova laboratory.

Templates

Success criteria

• linearity as expected
• bad pixels mask created
• bias and flat took
• All individual activity (in the table) success criteria are met.

Notes

• Save all the intermediate images to check the SHARK-NIR Data Reduction pipeline.

LBTO support

• Liquid Nitrogen refill is required in the cleanroom.
