What deflection do we want? For Auxtel the FOV is about 6 arcmin. From center to side it's 2000*0.1 arcsec = 200 arcsec = 3.33 arcmin. So a deflection of 2 arcmin seems decent. If we're 4m away from primary, spot is displaced by only 2mm. 
Problem with this config is beams are not very separated, spatially. We need a precision periscope on some to get more displacement. 




Meghan Notes

Note: start a parts list document!!

Mac mini control system

  • newport - start reading control manual for 2 degrees of freedom setup
  • system will now have beam splitters
    • do beamsplitter mapping
    • look at alternatives and categorize
  • clear a workspace
  • come up with plan and deadlines and weekly goals


SEMESTER PLAN:

  • end of Jan - conceptual design review complete
    • Tasks for Meghan
      • make a 4-5 slide slide deck where I make pictures describing the system (include part numbers, make list)
      • software architecture plan for controlling the mounts (can do during the lead time for hardware)
        • read control manual for whatever mount setup we order
        • If the adjustable hardware impeding timeline we abandon
      • Place beamsplitter order and put below deadlines on calendar

Conceptual Design Review

Meghan will create a detailed presentation (4-5 slides) describing the system we are to build and its purpose, and be as detailed as possible (including part numbers).

Meghan will then present this slide deck to Prof. Stubbs and Elana - we will find a time hopefully before Friday Feb 2.

Software/Hardware Preliminary Decisions

Meghan and Prof. Stubbs will decide on:

  • optical mounts for the beamsplitter cubes
  • type of computer hardware to control the optical mounts
  • begin a bill of materials

Above hardware should then be ordered (asap). 

Friday, Jan 26
Steerable Collimated Beam

Have a single, steerable collimated beam working. This will involve:

  • mount the beamsplitter on its adjustable mount and standardize this mounting system
  • mounting the light source and a single beamsplitter on the rail, and align them so that light goes through the beamsplitter (will be off-axis)
  • beam will be correct size (2") and collimated
  • there will be working software that is able to control where the beam is pointing
  • we can turn the beam on and off with software

Scale to Six Steerable Beams

Add the other beamsplitters so that the system is scaled to its full size.

  • mount other beamsplitters on rail in correct order and align so that all beams are of roughly equal intensity
  • do steering tests on all beams to make sure all parts are working properly

Local Telescope Test

Set up the system for the telescope we have here to test the differential monitoring. 

  • will need the beams to be relatively close together

preferably before 

Friday, April 26 

but there is some wiggle room


Initial steps:

  • read control manual for whichever steerable mounts we order
  • read some of the papers from the slack
  • make wiki organization clearer - separate page for meeting notes
