Previous: What Are The Advantages And Disadvantages of Multi-Slits?
Multi-slits can be use in one of two configurations on the RC Spectrograph at the 4-meter telescope. Both cover a full five arcminute field. The multi-slit replaces the normal decker in the spectrograph. The configurations are:
- Normal Configuration: The RC spectrograph using the normal off-axis collimator, 8x10-inch reflectance gratings, the UV Fast Camera and the T2KB CCD in a universal dewar. Resolution: 1.5-15 Angstroms.
- Cryogenic Camera Configuration: The CryoCam attaches to the RC Spectrograph using a lens collimator, grisms
and a dedicated Ford-Loral 800x1200 CCD in the camera. Resolution: 8-30 Angstroms.
