Today I worked with Mauricio and Laird on evacuating the air out of Clio’s cryostat, which involved cleaning the o-ring and then hoping for a good vacuum. Laird did some fixes to the ASM, removing the alignment laser and making an alignment fiducial instead, and fixing some of the protective covering on the back to keep out the dust. Jared and Alfio worked in the morning on software and electronics for the AO system, and in the afternoon and evening they with Laird tested the cleaned VisAO optics and closed her back up.
Song of the day for heavy-hearted basketball fans, if you need a cry 🙁
On a happier note, let’s close with some light-hearted fan mail from my sister:
VisAO and the WFS got a much needed spring cleaning today. We also installed some new filters.
Jared and Alfio installed a new more powerful Y-stage motor. This motor has to lift the W-unit against gravity, and the old one was under-powered and so was failing. These motors are very powerful, even the old one, so it is very nerve racking to mess around with them. We had a stressful morning.
T.J. and Katie buttoned up Clio today.
The weather has been gorgeous, and we’re seeing lots of locals out and about.
Here’s the song of the day. We have spent so much time here it now feels like we’re coming home when we get off the plane in La Serena.
