Lesedi HRS Project Wiki

  • This wiki is for construction of a high-resolution spectrograph on the 1-m Lesedi telescope in Sutherland. We anticipate future wikis for the user manual and for technical support.
  • The SAAO and Christian Schwab (Macquarie Univ. and AAO) are collaborating on the project.
  • The instrument is based on a design that Christian modified from NEID, an innovative HRS for use on the 3.5-m WIYN (https://neid.psu.edu/). We are hoping to reach a few m/sec accuracies for radial velocity measurements on Lesedi.

Documentation

  • Add notes from Christian's emails here
  • Detector notes and discussions
  • Rough purchasing list from Chris' visit 03/2018. He can likely supply the prism, collimator, and fiber injection:
   $35k  bench optics
   $55k Echelle grating
   $3k fiber injection optics
   $30k collimator/ADC.refocus mechanism
