P1.9 Check the working of the internal tip-tilt loop

• Phase : 2
• Status : Draft
• Category : Unpack, Assemble, and Verification (C1)???
• Recurrence : once at commissioning
• Duration : 1 day

Description

• Check the working of the internal tip-tilt loop using calibration unit light sources, C-RED2, and ALPAO-DM.

Prerequisites

• SCICAM cooled down.

Procedure

• Run the internal tip-tilt loop routine for different brightness of the source (star).
• Check its efficiency in keeping the PSF at the C-RED2 hot-pixel.
• Save data to repository and analyze them.

Success criteria

• Internal tip-tilt routine works fine and the PSF ar C-RED2 is stable within the required precision.
• All the data and analysis saved in the repository.

Notes

LBTO support

• Liquid Nitrogen refill is required in the cleanroom.
