How to Perform ARGOS AO Loop In Night Time

This HowTo describs what to do to set up the ARGOS system for night time observation. The procedure should start with hand over to warm up the lasers. It is recommendet but not absolutely necessary to start all software from scratch. That's included in this description.

Prerequisits

• Cleanup of day time work, like swing arm of CalUnitSystem is parked.
• System was properly shutdown before.
• Minimum the class 1 for lasers is required.

Note

• Currently (2018/02), ARGOS must be authorized to establish AOS connections, if not Power_up sequence ends with error (see troubleshooting).
  • Authorization must be performed at zenith. The dichroic moves in. This is done best at zenith!
  • Authorization must be completed. The GUIs show the authorization but the command is not completed!! Check TCS logs for completion.!!

Procedure (must be performed at handover to get laser stableized)

1. (Re-)start the software to be clean. (see: StartTheEasyWay).
2. Open the "Device GUI" (Applications->ARGOS Common)
3. Open the "Arbitrator GUI" (Applications->ARGOS ?X->arbitrator)
4. Open the "Status GUI" (Applications->ARGOS ?X->argos all status GUI)
5. Power up the system by pressing the "Power_up" button in the "Arbitrator GUI". This will take some time (SX about 10min, DX about 15 min)[
6. [In parallel to 5] Open AdSec GUIs (TODO: Adsec how to: HowToStartAdsec)
7. [In parallel to 5] Open FLAO GUIs and start up FLAO (see: HowToStartPyramidWfs)
8. [In parallel to 5] Open "CCD viewer" GUI (Applications->ARGOS ?X->CCD viewer)
9. [In parallel to 5] Open "AO sensing viewer" GUI (Application->ARGOS?X->argos ao sensing viewer)
10. Setup the system by pressing the "Setup" button. Motors and devices will be initialized. This will take about 3min.
11. Start up the system by pressing the "Start up" button. Now the lasers are lasing in the box.

To do the next steps of testing following requirements must be fulfilled.

• Fiber switch must be for AROGS (this is now done with authorizing as bentGregorienArgos)
• AdSec must be set.
• Telescope on zenith
• ARGOS must be authorized

Normally the previous two requirements are fulfilled after the telescope is prepared for observation by the telescope operator after hand over.

1. Press "Prepare" button to test the fast link FLAO to ARGOS connection and if a preset goes through - tests that FLAO is setup properly.
2. Press "Startup" button to get back into standby mode. If not the dust shutters stay open.

Further steps after telescope is open:

After the telescope is opened up you have to get ready for observation:

• Press "Prepare" button.
• Wait for the first preset from LUCI.

Troubleshoot

When	Where	What	Why	Solution
With POWERING_UP	SX	back to UNKNOWN	blue patrol camera does not connect when cold	press again power_up
With POWERING_UP	DX	time out exception	CCD is taking to long to cool down	press OK, and in case it goes back to UNKNOWN press again POWER_UP
With POWERING_UP	ANY	time out exception	various reasons	press OK, press again POWER_UP
With POWERING_UP	ANY	ERROR 'None Type' object has no attributes 'event Power up'	AArb is not connected with AOS	enable AArb in AOS GUI
