P2.4 SHARK-NIR alignment to the telescope

• Phase : 2
• Status : Draft
• Category : Daytime testing (functionality and operability) (C3)
• Recurrence : once after instrument installation at telescope platform
• Duration : 3 days

Description

• SHARK-NIR is aligned to the telescope, and the daytime collimation model is acquired.

Prerequisites

• All electronics and services are up and running.
• SHARK-NIR shutter open, and deployable arm (dichroic + IN-TT) deployed to get the light directed into SHARK-NIR.

Procedure

• Since SHARK-NIR has the same focal station as LBTI, the telescope is set to the LBTI collimation model to start the alignment of SHARK-NIR to the telescope.
• Using ARGOS on-axis calibration light source, IN_TT and Dichroic (of the deployable arm) are moved to have the on-axis spot on the reference position on SCICAM (and TECCAM), identified during the internal alignment of the instrument.
• TBD
• At the end of the alignment, check that our deployable arm, when un-deployed, does not vignette any of the technical FoV of LBTI (which is 120 more or less). Need to confirm if this activity can be performed only at night (authorize LBTI night collimation).

Templates

• SHARKNIR_gen_tec_PSFAlignment (not released)
• SHARKNIR_gen_tec_PupilApoAlignment (released)
• SHARKNIR_gen_tec_PupilLyotAlignment (released)

Success criteria

• On-axis spot from the ARGOS light source at the reference pixel of the SCICAM.
• The daytime SHARK-NIR collimation model is recorded.
• Something with LBTI?
• TBD

Notes

• For some reason, if the Argos swing arm calibration source is not good enough, we need to mount RR on the SX side and use that source.
• If needed, we can move the SOUL-WFS in x-y-z axes.

LBTO support

• Working platform installed in front of the Gregorian focal station SX.
• Argos swing arm and calibration source on SX side.
• Support from the LBTI team.
