Hectochelle: a multi-object echelle spectrograph for the converted MMT

PI: Andrew Szentgyorgyi

The Hectochelle adds a high dispersion capability to Hectospec's moderate dispersion with a second, very large bench-mounted spectrograph using an echelle grating. Hectochelle uses 240 of Hectospec's 300 fibers and Hectospec's robotic positioner and attains R~32,000 (sigma~4 km s-1) over single, filter-selected orders.
