MagAO-X 2024Aa Day 1: It lives!

The sun rising on a day of unpacking.

Is there anything more tantalizing than an fresh, unopened box of MagAO-X? This team just couldn’t resist. The unpacking festivities started at the first call of the returning night shift astronomers and did not finish until our good friend Orion had completely risen.

The very first gift of the day was an early morning Carlos Culpeo spotted by a Josh who’s sleep schedule hasn’t quite agreed with all the travel yet. This curious fox was later spotted at lunch, and we hope he becomes a regular.

After a reviving breakfast of the highest LCO standards, we shuttled up to the clean room and got to work on our hard hat activities. This includes the reverse of everything we did in Tucson (see Logan’s packing video) but enjoy these snapshots of cranes and dollys and etc. to jog your memory.

Geared up and ready!

aaaand all the bolts had to go right back on the empty shipping box.

We were so fast and efficient, we had time to catch another fan favorite, Gary, who wandered up to the parking lot to check on what we were up to.

With another good animal omen bestowed upon us, and lunch in our stomachs, we got back to work freeing the electronics box from it’s larger, wooden box. Don’t try this at home kids, these are advanced crane moves best performed with at some two professionals and at least four grad students standing around in hard hats, looking anxious.

And all of a sudden, MagAO-X was out of it’s box and in the clean room, and it was only 3pm! Every time, it seems like we do it faster. Even our crane operator Juan was surprised. About at that time we all were ready for some caffine, and a break from hard hats.

The much needed 4pm coffee break

Woof. What a blog post. We’ve unpacked it, so we must be done, right? What, we still need to set up the clean room? You mean we’re only halfway through? Well… if this blog post is long, it’s only because you’re right there in it with us.

Before we could do anything else, the clean room had to get… actually clean. The youngest and spry-est of us took on the challenge. Special recognition to Katie for surviving the fumes of the glass cleaner long enough to finish the clean room mopping.

The classic big mop and aerosol combo.
Three cheers for cleaning what no one wanted to clean!
And still, everything looks alright!
panels coming off! more bolts!
Checking out what’s up with Vis-X

Once Laird arrived, some initial optical inspection occurred! Welcome Laird! Turns out you can only do so much without the cameras on to tell you what’s misaligned, so the real alignment will have to wait for tomorrow.

We ran into some unexpected traffic on our way back up to the cleanroom from dinner at the lodge:

Once we were finally clear, we finished up with the nitty gritty of glycol and cabling

Checking that there are no leaks, and the coolant is running smoothly.
Passing on re-cabling secrets to the next generation.

The good news? ITS ALIVE. All of the computers have turned on, the new GPUS hare happily chugging along, and we are ready for the DM cabling and alignment tomorrow. If you made it this far, congratulations, you have gotten through what will probably be our second longest day of the run.

Happy sunset
Green flash?

Wow, does it feel good to be back.

Maggie says we gotta have some nature? Here’s a cool condor shot I took today!

MagAO-X 2024Aa Day 0: Why are you not making my salad?

It’s been a whole year but the team is back! The unpacking and alignment crew arrived at the beautiful Las Campanas Observatory this afternoon.

Josh is there we promise!

Fun fact: if you have items to declare upon arrival to Chile, your line takes you to a fun sign that only you and your advisor get to see.

Happy travelers

Once we arrived at LCO, we got straight to work! Well we did as much as we could until dinner…

We set up our first instrument computer, “AOC”, then got out of the way so the LCO crew could mop the clean room in prep for our long day of unpacking tomorrow.

We are big fans of the new decals highlighting the copious wildlife at LCO!

It’s practically a zoo!

We are also big fans of the newly established salad bar during dinner! However, this new station did confuse our postdoc, prompting him to wonder about his salad’s whereabouts (see title).

Finally, a good omen for the run ahead of us: a satisfying viscacha siting this afternoon.

Blog Rules: The only rule I’ll implement as the first blogger of this run is that you must incorporate a native plant or animal in your blog. Today’s “song of the day” is the wind quietly blowing over the Atacama Desert.

GMagAO-X’s first PDR

Maggie giving her HCAT talk, overviewing phasing on the testbed.

GMagAO-X just hit another big milestone, we just finished up its Preliminary Design Review (PDR). If you haven’t been to one before, a PDR is a chance for a design to be critiqued and tweaked before moving on. If a project does well on its PDR, it’ll have good reason to be funded and moved to its next phase, the Final Design Review (FDR). If the committee finds it needs more work, an instrument might have another PDR in its future (this has happened to a few other ELT instruments).

Our hope is that GMagAO-X becomes a first light instrument at the GMT, and the PDR is a huge first step.

A huge thanks to the committee members who made their way to Tucson to give their expertise to the exercise:

  • Antonin Bouchez (who previously worked with GMT AO, and now is the director of AO at Keck)
  • Dimitri Mawet (PI for KPIC, the High contrast fiber fed instrument at Caltech)
  • Mike Bottom (UHawaii)
  • Markus Kasper (ESO)
  • Alan Uomoto (Carnegie Observatory)

The two days were filled with talks about everything from science motivation, to optical design, to predicted schedule and budgeting. We got to do it all in Steward’s historic dome, specially outfitted for the experience.

Since we had them out here in Tucson, the festivities got to include gadgets like a to scale model of of the GMagAO-X design, a non-functional 3K like the ones planned on in the design, and the patented optical locking clamp. Maggie also got a chance to show off the HCAT bench, for some hands on learning.

The 3D printed instrument, it rotates!

This was also a good chance for the rest of the team to catch up on where the GMagAO-X project is at.

Miscellaneous grad student attendees.

Thank you again to all the people who put in the work to pull the two days of review together, the committee for their attention and helpful comments. GmagAO-X is a stronger instrument because of the PDR!

2024Aa Packing Party

MagAO-X is up and off to the great mountain in the south! As we are approaching our next great observing run, this time in two parts: 2024Aa in March (14 nights) and 2024Ab in May (10 nights). We spent the week packing her up and buttoning her down, and today saw her stuffed into the shipping truck and waved goodbye.

Our mascot for this run is the Bubo Magellenicus, or the Lesser Horned Owl (of fluffy–butt allsky cam fame)

Please enjoy this video and pics of the week’s events.

CfAO Fall Retreat: high contrast chats in the hills

Hello from Arizonans in California! I just got back from the UC Santa Cruz Center for Adaptive Optics (CfAO) Fall retreat, where members of the AO work through some of the pressing problems in the field. This year was focused on High Contrast imaging testbeds, lessons learned from Magellan’s MagAO-X and Subaru’s SCExAO and what might be in the cards for Keck, and a round up of adaptive Secondary progress – LBTO, MMT, and the future of IRTF, KECK, and beyond.

The Arizona Telescopes representing, Me representing MagAO-X (Magellan Clay), Robin and Jacob the Toronto part of MAPS (MMT), and Sam Ragland (LBTO)

Some of the likely suspects were around, namely Jacob and Robin from UToronto representing MMT calibration work and Sam Ragland from LBTO operations. Thanks to a very generous student scholarship from the workshop organizers, I was able to attend and represent MagAO-X’s progress.

If someone had taken a picture of me presenting, it would look a little like this.

Sam’s update on the LBT’s progress was some of the most concrete work concerning a long-term Facility adaptive secondary, in this case using adOptica technology. Sam discussed the re-coating of the secondary, and future plans, including adopting an ASM from CHile, close to this group’s heart.

Sam Ragland giving an update talk on LBTO’s work with Adaptive Secondaries.

Jacob got the longest student talk of the conference, and got to spend an hour discussing his method for calibrating on sky. A key difference between the LBTO and other telescopes discussed being that LBTO is a Gregorian design with an intermediate focus that allows for daytime calibrations of their secondary. MAPS and systems like IRTF and Keck are Cassegrain design with no focuses before the primary, and can only take calibration matrices on a bright star on sky. Making the operating software and calibration procedure robust in the meantime is a huge step towards making these systems reliable and facility class.

Jacob Taylor presenting on one method MAPS uses for on sky calibrations.

We also got one last GMT talk from Antonin, who has recently moved from his role on GMT to the AO scientist for the Keck twin 10ms. He gave an update on the current design of the GMT adaptive secondaries, which will be using a similar technology to what’s currently on LBT. In fact, we learned that the rigorous modeling and testing on the GMT prototypes solved a resonance issue that LBT had unexplained.

Antonin Bouchez reprising his past role of GMT AO lead to talk about advancements in the GMT secondary design. He has recently accepted an AO position at Keck.

I cannot express how grateful I am to have a community that shares and collaborates as this one does. Even though MagAO-X is already built, there’s a lot to learn from the discussions that Keck is having about their own testbed. As in, what areas of interest are already met by our technology? What new avenues are being pursued? And where do all fit in the the US high contrast family?

Took a quick break to see the hills of Santa Cruz

Thank you to everyone who made this conference so fruitful! And to the organizing committee for the student scholarship.
