Daily Startup

The steps below assume that the steps in System Startup are complete. This will generally be the instrument state on a daily basis.

  1. Ensure MagAO-X processes are started on AOC, ICC and RTC. We do this by running xctrl status on each machine.

    # starting with AOC:
[xsup@exao1 ~]$ xctrl status
# verify processes are all green/running
# next on ICC:
[xsup@exao1 ~]$ ssh icc
[xsup@exao3 ~]$ xctrl status
# verify processes are all green/running
[xsup@exao3 ~]$ exit
# now for RTC:
[xsup@exao1 ~]$ ssh rtc
[xsup@exao2 ~]$ xctrl status
# verify processes are all green/running
[xsup@exao2 ~]$ exit

A useful further check is to run getINDI on each machine to verify that INDI server is communicating.

Note

All software on all machines should be up and running with good INDI communications. If it is not you can not begin to power up because you won’t be able to observe what happens.

  1. Ensure that you have working GUIs which are connected to INDI.

Note

This must include a display of the log stream that you are able to see at all times.

  1. On the pwrGUI ninja tab, verify the following items are on:

    • pdu3.blower

    • pdu3.rackfans

    • pdu3.instCool

    • usbdu0.rhtweeter

    • usbdu1.rhncpc

Warning

If any of these indicate off, stop and investigate. These are safety issues and you should not go on.

  1. On the pwrGUI ninja tab, verify that the following items are on:

  • pdu0.dcpwr

  • pdu0.compicc

  • pdu0.comprtc

Note

If any of these are off, the instrument probably won’t work.

Warning

You must be monitoring the relative humidity for dmtweeter and dmncpc any time their power is on.

  1. Use the pwrGUI to power up the MagAO-X components

    • Verify that humidity for both rhtweeter and rhncpc are below 15%.

    • On the user tab power everything on.

      • camvisx and stageff can be left off if not needed

      • If you are using GMT HCAT, all devices on pduhcat can be powered on (you won’t see this at LCO)

    • If you plan to use either camflowfs or camllowfs, check their power in the ninja tab. If they are not powered up:

      • begin with both cameras powered off

      • on exao3/ICC: xctrl shutdown camflowfs camllowfs

      • power on one or both cameras

      • as a non-xsup user, on exao3/ICC, run sudo /opt/pvcam/drivers/in-kernel/pcie/hotplug_pcie.sh, verify the number of “active cameras” it reports

      • on exao3/ICC: xctrl startup camflowfs camllowfs

  2. Once power up is complete, switch to lab mode by running the xlabmode script as xsup on aoc:

    # Run on AOC:
[xsup@exao1 ~]$ xlabmode

    This will move stagepickoff to the lab position and ensure the ADCs and K-mirror are in the correct position.

  3. Set the flat on the dmwoofer, dmtweeter, and dmncpc.

  4. Now on the Alignment GUI:

    • set the pyramid modulator under “Modulaion”

    • set TTM Pupil

    • set TTM Peri

  5. Optional, but recommended Set the toggles on sysMonRTC.set_latency.toggle and sysMonICC.set_latency.toggle to “On” using cursesINDI.

  6. At this point you should see a PSF image on camtip, probably with a fair amount of aberration.

Aberrated camtip PSF

An AO system would clean that right up.

  • If you do not see anything, use the system block diagram to troubleshoot. The most likely causes are that you forgot to power something on (the source?) or that stagepickoff is in the wrong position. Another possibility is that flipwfsf is in, but fwtelsim is in VisOpen which blocks IR light.

  1. Setup camwfs using the camwfsCtrl GUI:

    • set the FPS to the desired loop speed (for the default calibration, 2000 Hz)

    • toggle synchro to “on”

    • close the shutter

    • take a dark

    • open the shutter

  2. On the Alignment GUI, under “Modulation”:

  • input the Frequency [Hz] (for the default calibration, that is 2000 Hz) and hit enter

  • input the Radius [l/D] (for default, 3 lambda/D) and hit enter

  • Note that your newly entered values won’t appear until modulation begins.

  • click Modulate

  • the status text should change to CONFIGURING. Wait for it to say MODULATING.

  • confirm that the PSF on camtip has become a donut

  1. The cameras with temperature control will start cooling themselves down immediately on software startup, and should be cold by now. Check on them.

  2. Optional, but recommended Set the toggles on sysMonRTC.set_latency.toggle and sysMonICC.set_latency.toggle to “On”.

  3. Setup CACAO for closing the high-order loop as in CACAO Setup

  4. Now align the system as in alignment
