HIPPI-2 Comes Together

HIPPI-2 (in its entirety) in the Hilo Lab in June.

Jeremy Bailey, PI of the small, high-precision polarimeter HIPPI-2, paid a visit to Hilo in June in order to set up the instrument. The visit went well, the mechanisms all checked out, and test data was obtained. Measurements of a test light source revealed that the efficiency of the polarization modulation looks good. HIPPI-2 is likely the smallest instrument ever mounted on Gemini; its scale is seen in this photograph. We’ll need a *large* amount of counterweighting when it’s on the telescope for commissioning in July!
