[10.02] The J-band camera system for the Hobby-Eberly telescope

J.J. Beatty, J.C. Charlton, C.W. Churchill, L.W. Ramsey (Penn State)

The J-band camera system, or JCAM, is an simple extension to the current HET commissioning spectrograph to allow moderate resolving power (7,000 < R < 13,000) spectroscopy in the near-infrared. The JCAM system will replace the current echelle grating, cross disperser, camera, and detector in the Upgraded Fiber Optic Echelle (UFOE) currently at the HET site. The camera has a five element all-refracting design. The detector system is a 1024x1024 Hawaii array housed in an IR Labs dewar and provides full coverage from 0.98 - 1.34 microns in a single exposure. The detector electronics utilizes a VME-based PC driving custom control and signal processing electronics.

At the resolution of JCAM only ~10% of the spectrum is contaminated by night sky lines. It will be possible to obtain S/N ~30 per resolution element in one hour on a J=18 object.
