Chile Trip Planning

Chile Trip Planning

Planning for the next trip to Chile (tentatively scheduled for January 2023)

Things to do:

  • install anemometer power supply, if not done already
  • install remotely controlled power strip
  • install new fiber-slit coupling system for OSELOTs
    • two options: glue the current fiber mount to slit, or use Sasha's new system

Things to acquire/bring:

  • remotely controlled power strips (PDUs)
  • backup 5 mm slit for OSELOTs
  • Sasha's new OSELOTS fiber coupling system
  • new lithium battery

Sept 11 2022 planning for Nov 2022: 

A. revision of image quality instrumentation

B. revive top end tension meter- requires taking oscilloscope with Fourier analysis. 

Both of these should require only power, no exiting cables. 

  1. move differential temperature sensors onto telescope trusses
    1. extra cable, soldering iron, hand tools, heat shrink, power strip and extension cord
    2. find source of short and eliminate it
  2. perhaps mount anemometer on fork mount? 
  3. install new anemometer power supply, probably redo connections to lab jack if it's moved
  4. check (and possibly redo) OSELOTS alignment

Pre-requisites: 1) Ship box of stuff to Pachon, 2) verify data paths back to Boston

Ship ahead of time:
