Polarimetric Instrumentation at the DAO

D. Monin

Observations of stellar magnetic fields have been carried out with the Dominion Astrophysical Observatory's (DAO) 1.8-m Plaskett Telescope for more than 10 years using the in-house built spectropolarimeter, dimaPol. This instrument was inspired by John Landstreet's Balmer line polarimeter. I'll briefly describe the instrument and how it has generated interest in polarimetric instrumentation development at HAA. As a result HAA is now involved in an effort to refurbish the Gemini Facility Polarization Modulator (GPOL). I'll provide an outline of this project as well.
